Batteries Inc. (batteriesinc.net) sells batteries in wholesale, bulk, and custom-pack formats, so the main things to check before ordering are the brand line, the exact voltage/capacity/terminal spec, the pack quantity, and the current sale price versus the original price shown on each product page. It is a reasonable starting point if you already know the battery type you need and want to compare per-box pricing across Duracell, Energizer, Power-Sonic, and similar brands. It is less useful if you need help sizing a battery for a specific device, since the site presents products rather than selection guidance.

Brand lines and what they signal

The catalog mixes consumer and industrial/professional lines, and the line name matters more than the brand name alone.

Practical implication: Procell and Energizer Industrial boxes are sold as bulk replacement stock, usually 12 per box, and are priced per box. Power-Sonic items are single rechargeable batteries priced per unit, not per case.

Specs you must match before ordering

For the Power-Sonic SLA range, three fields decide whether the battery physically fits and works:

• Voltage and capacity — all listed units are 12V, but capacity ranges from 12 AH to 100 AH. Capacity is not interchangeable; a 12 AH unit will not substitute for a 100 AH unit in a backup application.
• Terminal type — the site distinguishes U terminals, NB (nut and bolt), and F2. These are not compatible with each other without adapters or different cabling.
• Physical size — larger AH ratings generally mean larger, heavier cases, so confirm the compartment dimensions before buying.

Examples from the catalog to make the distinction concrete:

• PS121000 — 12V, 100.0 AH, U terminals
• PS12550 — 12V, 55 AH, U terminals
• PS12350 — 12V, 35 AH, NB terminals
• PS12280 — 12V, 28.0 AH, NB terminals
• PS12260NB — 12V, 26 AH, nut and bolt terminals
• PS12180 — 12V, 18 AH, F2 or NB terminals
• PS12120F2 — 12V, 12 AH, F2 terminals

Note that PS12180 is listed with a terminal choice, while most others are fixed to one terminal type. If your application needs a specific terminal, that flexibility is worth checking per product rather than assuming.

Pack quantity and how it affects unit price

Most non-SLA products are sold by the box, and the box count is part of the product name:

• Duracell Procell Intense CR123 — 12 per box
• Duracell Procell PCCR2 — 12 per box
• Duracell PC1604 Procell 9V — 12 per box
• Energizer Industrial EN22 9V — box of 12
• Duracell PC2400 Procell AAA — box of 24

To compare value, divide the current price by the number of cells. For example, the Procell Intense CR123 box at $27.60 works out to $2.30 per cell, while the PC2400 AAA box at $15.00 for 24 cells is $0.625 per cell. Comparing headline box prices across different pack sizes will mislead you.

The site does not state quantity-break tiers beyond the box, so if you need multiple boxes, the per-box price shown is the figure to work from unless a bulk discount is displayed at checkout.

Price and promotion signals

Every product in the evidence shows a struck-through original price and a lower current price, which indicates an active sale rather than a permanent list price. Examples:

Two cautions:

1. Sale prices change. Confirm the current price on the product page at the time you order rather than relying on a cached figure.
2. The site advertises "Free Shipping," but the evidence does not state a minimum order value or which destinations qualify. Treat free shipping as a claim to verify at checkout, not a guaranteed term.

Custom battery packs

The site positions itself as a source for custom battery packs in addition to stock items. The only assembled pack visible in the evidence is the DL-40 Door Lock Battery Pack, 6V alkaline, built with Duracell AA Coppertop cells. That example shows the pattern: a standard cell assembled into a finished pack for a specific device. If you need a custom configuration, expect to specify voltage, cell type, capacity, terminal/connector, and physical dimensions, since those are the fields the stock listings are organized around.

A quick pre-order checklist

1. Identify the exact model or spec you are replacing — voltage, capacity (AH for SLA), and terminal type.
2. Match the brand line to the job: Procell/Energizer Industrial for bulk disposable replacement, Power-Sonic for rechargeable 12V.
3. Check the pack count and calculate per-unit price before comparing products.
4. Confirm the current sale price and whether free shipping applies to your order at checkout.
5. For SLA, verify physical dimensions and terminal type against the old battery, not just the AH rating.

If you are replacing a battery you already have, the fastest route is to read the model number off the old unit and search for that exact string — the catalog uses full model numbers such as PS12550 and PC1604, so a precise match avoids terminal and capacity mismatches.

Choose by what your device needs, not by brand or price alone. At Batteries Inc, the three main chemistries map to three different jobs: alkaline for everyday disposable power (AAA, 9V), lithium for small high-drain or long-shelf-life devices (CR123, PCCR2), and sealed lead acid (SLA) for rechargeable 12V systems where capacity in amp-hours (AH) and terminal type matter most. If your device is rechargeable and runs on 12V, you want SLA. If it takes a standard disposable cell, alkaline or lithium is the decision.

Start With Three Questions

Before picking a product, answer these in order:

1. Does the device recharge? If yes, and it uses a 12V block, you need sealed lead acid. If it takes disposable cells, go to question 2.
2. What size and voltage does the battery compartment require? AAA, 9V, CR123, and 12V SLA are not interchangeable.
3. Does the device have a high continuous drain or sit unused for long periods? That pushes you toward lithium over alkaline.

Alkaline: Everyday Disposable Power

Alkaline is the default for low-to-moderate drain devices that take standard cells — remotes, clocks, smoke detectors, toys, and many 9V applications.

At Batteries Inc, alkaline options include:

Choose alkaline when: the device takes standard disposable cells, drain is light to moderate, and you want the lowest cost per cell. Avoid it when: the device runs hot, drains fast, or sits for years between uses — alkaline cells can leak over long storage.

Lithium: Small Cells for High Drain or Long Storage

Lithium cells appear at Batteries Inc mainly in the CR123 and PCCR2 formats. These are 3V cells used in security cameras, flashlights, medical devices, and other compact equipment that either draws heavily or needs reliable power after long shelf life.

Choose lithium when: the device specifies CR123 or a similar lithium cell, or when you need stable performance in cold conditions or after long storage. Don't substitute an alkaline cell for a lithium one unless the device explicitly allows it — voltage and discharge behavior differ.

Sealed Lead Acid: Rechargeable 12V by Capacity

SLA batteries are the rechargeable option, and at Batteries Inc they're listed as 12V Powersonic units differentiated mainly by amp-hour (AH) capacity and terminal type. Capacity tells you how long the battery can run a given load; terminal type tells you whether it physically connects to your equipment.

Choose SLA when: your device is a 12V rechargeable system — UPS units, mobility equipment, alarm panels, backup power, or similar. Match two things exactly: the AH rating your device expects (higher AH generally means longer runtime, but confirm the compartment fits the physical size) and the terminal type (F2, NB, or U terminals are not interchangeable without adapters).

Matching Chemistry to Device: A Quick Decision Table

Common Mistakes to Avoid

• Buying SLA by voltage alone. All the Powersonic units above are 12V — the real differences are AH capacity and terminal type. A 12 AH and a 100 AH battery are not substitutes even though both say 12V.
• Assuming higher AH always fits. Larger capacity usually means a physically larger battery. Check your compartment dimensions before ordering.
• Mixing terminal types. F2, NB, and U terminals connect differently. If your device uses nut-and-bolt terminals, an F2 battery won't seat without modification.
• Using alkaline where lithium is specified. Some devices require lithium's voltage or discharge curve and won't work correctly on alkaline.

What to Check Before You Add to Cart

1. Confirm the chemistry your device requires (disposable alkaline, lithium, or rechargeable SLA).
2. For SLA, confirm both the AH rating and the terminal type.
3. For pack purchases, note the quantity per box — Batteries Inc lists many items as boxes of 12 or 24.
4. Check the listed price at checkout, since many items show sale pricing that differs from the original price.

Custom battery packs at Batteries Inc are battery assemblies built to match a specific device's requirements — cell type, voltage, capacity, terminal style, and physical shape — rather than a standard off-the-shelf cell. You'd look for one when a device needs a battery that doesn't exist as a standard size, when you need a specific voltage/connector combination, or when you're replacing a pack that was designed for one product. Batteries Inc sells these alongside standard branded batteries (Duracell, Energizer, Power-Sonic, Omni-Cel, Rayovac) and wholesale/bulk options, so the custom pack is one part of a broader catalog rather than a separate service.

What "custom" actually means here

A custom battery pack is defined by the device it powers, not by the brand of the cells inside. The variables that get specified are:

• Cell type and chemistry — e.g., alkaline AA cells, lithium cells, or sealed lead acid (SLA) blocks
• Voltage — determined by how many cells are wired in series
• Capacity — determined by cell size and how many are wired in parallel
• Terminals and connectors — the physical interface to the device (U terminals, nut-and-bolt, F2, wire leads, etc.)
• Physical form — the pack's dimensions and mounting shape, so it fits the compartment

A useful example from the site's own catalog: the DL-40 Door Lock Battery Pack, 6V Alkaline, described as "Assembled w/ Duracell AA Coppertop." That's a custom pack in the plainest sense — four AA alkaline cells assembled into a 6V pack shaped and terminated for a specific door lock, using a named brand of cell inside. It isn't a standard battery you'd buy loose; it exists because that lock needs 6V in a particular form factor.

What they're used for

Custom packs show up wherever a device's power requirement doesn't line up with a standard cell:

• Access control and door locks — the DL-40 example above; locks often need a specific voltage and a pack that fits inside the lock body or a small compartment
• Security and alarm systems — panels and sensors that need a defined voltage and a connector that plugs into a board
• Backup and standby power — SLA packs used in UPS-style or emergency lighting roles, where a specific amp-hour rating and terminal type matter
• Industrial and OEM equipment — devices built around a pack spec rather than a consumer battery size
• Replacement packs for discontinued devices — when the original pack is no longer sold, a custom assembly restores the device

The common thread: the device dictates the spec, and the pack is built to that spec.

Custom packs vs. standard batteries

The practical difference is that a standard battery is interchangeable across many devices, while a custom pack is usually tied to one.

What to confirm before buying

Because a custom pack is device-specific, the compatibility check happens before purchase, not after. Confirm:

1. Voltage — match the device's requirement exactly; a 6V lock needs a 6V pack, not a 9V one.
2. Capacity (Ah/mAh) — for SLA packs especially, the amp-hour rating determines runtime. The site lists SLA options across a wide range, from 12V 12AH up to 12V 100AH, so the rating is a real selection variable, not a formality.
3. Terminal type — U terminals, nut-and-bolt (NB), F2, or wire leads. A pack with the right voltage but the wrong terminal won't connect. The catalog distinguishes these explicitly (e.g., "PS121000, U Terminals" vs. "PS12350, NB Sealed Lead Acid").
4. Physical dimensions — measure the compartment; a pack that fits electrically but not physically is unusable.
5. Chemistry — alkaline, lithium, and sealed lead acid behave differently in temperature range, rechargeability, and disposal. SLA packs are rechargeable; the alkaline DL-40 pack is not.

If you're replacing an existing pack, the old pack's label usually carries voltage, capacity, and sometimes a part number — that's the fastest route to a match.

Where custom packs sit in the wider catalog

Batteries Inc positions itself as a source for wholesale, bulk, and custom battery packs, with free shipping noted on the site. The catalog mixes:

• Branded standard cells in bulk boxes — e.g., Duracell Procell Intense CR123 (12 per box), Duracell Procell PCCR2 lithium (12 per box), 9V Duracell PC1604 Procell (12 per box), Energizer Industrial EN22 9V (box of 12), AAA Duracell PC2400 Procell (box of 24)
• Sealed lead acid packs in a range of capacities and terminal types — Power-Sonic PS121000 (12V 100AH, U terminals), PS12550 (12V 55AH, U terminals), PS12350 (12V 35AH, NB), PS12280 (12V 28AH, NB), PS12260NB (12V 26AH, NB), PS12180 (12V 18AH, F2 or NB), PS12120F2 (12V 12AH, F2)
• Assembled custom packs — like the DL-40 door lock pack

Prices shown on the site are sale prices with original prices struck through (for example, the DL-40 lists at $7.95 reduced to $4.85; the PS121000 at $328.90 reduced to $262.90). Treat listed prices as current-at-listing, not permanent.

The short version

A custom battery pack is a battery built to a device's spec — voltage, capacity, terminal, and shape — instead of a standard cell size. At Batteries Inc they're sold alongside bulk branded batteries and SLA packs, and the clearest example in the catalog is the 6V DL-40 door lock pack assembled from Duracell AA cells. Buy one when your device needs a voltage/terminal/form combination that no standard battery provides, and confirm voltage, capacity, terminal type, and physical dimensions against the device before ordering.

Batteries Inc (batteriesinc.net) is an online battery retailer that sells name-brand consumer batteries in wholesale and bulk quantities, plus custom-assembled battery packs. It is aimed at buyers who need more than a single retail pack — businesses, repair shops, facilities, and anyone sourcing batteries by the box or case. If you only need one or two batteries, the site still works, but its structure and pricing are built around multi-unit and bulk orders.

What the site is positioned as

The site describes itself as "your primary source for batteries: wholesale, bulk, and custom battery packs." That framing tells you the intended audience: buyers who purchase in volume or need a pack built to a specific voltage and configuration, rather than walk-in retail customers.

Free shipping is promoted on the site, which matters most for bulk orders where shipping weight would otherwise add up.

What it sells

Branded consumer batteries

The catalog carries well-known brands including Duracell, Energizer, Power-Sonic, Omni-Cel, and Rayovac. Common formats include:

• Alkaline: 9V, AAA, and AA cells sold by the box (for example, 12-packs and 24-packs)
• Lithium: CR123 and PCCR2 3-volt cells sold 12 per box
• Sealed lead acid (SLA), rechargeable: 12V batteries in a range of capacities

Sealed lead acid batteries

The SLA lineup is where the bulk and industrial focus shows most clearly. Listed capacities include 12V at 100 AH, 55 AH, 35 AH, 28 AH, 26 AH, 18 AH, and 12 AH, with terminal types such as U terminals, NB (nut and bolt), and F2. These are the batteries used in UPS units, alarm systems, mobility equipment, and similar applications.

Custom battery packs

Beyond individual cells, the site sells assembled packs — for example, a 6V alkaline door lock battery pack built with Duracell AA Coppertop cells. This is the "custom battery packs" part of the positioning: if a device needs a specific voltage or form factor that isn't a standard retail item, a pack can be assembled to match.

How pricing works

The site runs frequent sale pricing, with original and current prices shown side by side. A few examples from the catalog:

Prices change, so treat these as examples of the discount pattern rather than fixed figures. Checkout is handled through the site's own checkout page.

Who it fits

• Good fit: buyers ordering by the box or case, anyone replacing SLA batteries in equipment, and anyone who needs a non-standard pack assembled from name-brand cells.
• Less of a fit: someone who wants a single AA or 9V battery at retail convenience-store pricing, or who needs same-day local pickup.

What to check before ordering

1. Match the exact model number, not just the voltage. SLA batteries with the same voltage differ in capacity (AH) and terminal type (U, NB, F2), and the wrong terminal won't fit your equipment.
2. Confirm quantity per unit. Many listings are priced per box of 12 or 24, so the unit price is per cell while the line price is per box.
3. Verify the pack specification if ordering a custom assembly — voltage, cell type, and connector need to match the device.
4. Watch sale pricing, since discounts on this site are substantial and change over time.

Batteries Inc runs a standard online store: you browse products, add items to a cart, and check out through a single checkout page at batteriesinc.net/checkout/. The site advertises Free Shipping, and product listings show both an original price and a discounted "current price," so the price you pay is the one shown at checkout. Before ordering, confirm the exact model number, quantity, and terminal type (for example, U terminals vs. NB terminals on the Power-Sonic sealed lead acid batteries), because those details determine whether the battery physically fits your application.

The ordering flow

1. Find the product. Listings are organized by brand and type — Duracell and Energizer alkalines, Power-Sonic sealed lead acid (SLA) batteries, and assembled packs like the DL-40 Door Lock Battery Pack.
2. Check the specs on the listing. For SLA batteries, the title carries the critical information: voltage, amp-hour capacity, and terminal style. Examples from the catalog:
   • 12 Volt 100.0 AH Powersonic PS121000, U Terminals
   • 12 Volt 35 AH Powersonic PS12350, NB Sealed Lead Acid
   • 12 Volt 12 AH Powersonic PS12120F2 Terminals
3. Add to cart. Each listing has an "Add to cart" action.
4. Check out. The cart leads to the checkout page at batteriesinc.net/checkout/, where the order total is finalized.

What the pricing looks like

Listings display a struck-through original price alongside a current sale price. A few examples from the site:

Because these are sale prices, treat the figure shown at checkout as the one that applies to your order. The site does not publish a separate price list outside the product pages.

Shipping

The site states Free Shipping as a headline benefit. The available page content does not spell out the conditions — whether free shipping applies to every order, only to orders above a threshold, or only within certain regions. If shipping cost matters to your decision, confirm it at checkout before completing the order rather than assuming it applies to your cart.

Before you click "Add to cart"

• Match the terminal type. U terminals, NB (nut and bolt), and F2 terminals are not interchangeable in most equipment. The terminal code is in the product title for a reason.
• Match capacity, not just voltage. A 12V 12 AH and a 12V 100 AH battery are both "12 volt" but serve very different runtimes and physical footprints.
• Confirm chemistry. Alkaline (Duracell Procell, Energizer Industrial) is for disposable use; sealed lead acid (Power-Sonic) is rechargeable. Choosing the wrong chemistry means the battery won't work in a charger or device designed for the other type.
• Check pack quantity. Many listings are sold by the box — 12 per box for the CR123 and 9V items, 24 per box for the AAA Duracell PC2400 — so the unit price is per battery, not per box.

Common snags

• Sale prices change. The gap between original and current price varies widely across listings (some are roughly 30% off, others closer to 50%), which suggests promotions rotate. If you're comparing against another supplier, compare against the current price, not the original.
• Assembled packs vs. loose cells. Items like the DL-40 Door Lock Battery Pack are pre-assembled with specific cells (Duracell AA Coppertop in that case). If you need a specific cell inside the pack, check the description rather than assuming.
• No published shipping terms. Since the site only advertises "Free Shipping" without stated conditions, the checkout page is the authoritative source for your actual total.
