When a camera dies mid-shoot or a flashlight gives up on a night walk, the culprit is almost always a tired cell. Lithium 123-style batteries run the gear you rely on most: film cameras, motion sensors, tactical lights, and smart-home devices. Picking the right one means fewer surprises, longer runtimes, and a drawer full of spares that actually work when you reach for them. The lineup below covers photo cells, 9V packs, and bulk CR123A stock for households running lots of small electronics. Each pick earns its spot for a specific reason, so match the cell to the job and skip the guessing.

A Deeper Look At The Lineup
A single Energizer 123 lithium cell is the lowest-commitment way to test whether your device actually needs a swap or just a clean contact. Sold as a one-pack, it suits a quick replacement in a film camera or a flashlight that suddenly stops firing. The 3V chemistry holds steady across temperature swings, which matters if you keep gear in a garage or car through the seasons.
For a first-timer trying lithium cells for the first time, the single-pack is a sensible test drive. Owners running lots of gear will burn through it fast and want a multi-pack instead.
The Case For It
- Low-risk way to confirm your device actually accepts lithium 123 chemistry.
- Wide operating range helps in unheated spaces like sheds and vehicles.
- Long shelf life means the spare stays usable through months of drawer time.
- 3V output matches the spec most photo and flashlight devices demand.
Things To Consider
- A one-pack offers no backup for households running multiple devices.
- Per-cell cost runs higher than the multi-pack Energizer picks further down this list.
Best Suited To
First-time shoppers testing whether their camera or flashlight responds to a fresh lithium cell.
Look Elsewhere When
Anyone stocking a drawer for a full household of devices will find the Energizer 123 2-Pack a more practical fit.
The CR2330 coin format is the kind of cell you forget about until your car key fob stops responding or a kitchen scale goes dark. Loopacell ships a 15-pack of fresh 3V coin batteries designed to replace DL2330, BR2330, ECR2330, and other equivalents. You get enough spares to cover watches, small remotes, and a few CMOS memory-backup slots in older computers.
For anyone tired of hunting through hardware store bins for a single odd-size cell, this pack clears the shelf for years. Compared with the bulk rapthor CR123A further down, this is a different form factor entirely, built for low-drain coin slots rather than high-drain flashlights.
Good Reasons To Consider
- 15-count pack covers several devices without repeat orders.
- Direct cross-reference for DL2330, BR2330, and ECR2330 equivalents.
- Coin format fits watches, key fobs, calculators, and CMOS backup slots.
Worth Noting
- Coin cells are small and easy to lose during a swap, so a tray helps.
- Not a substitute for the cylindrical CR123A cells used in flashlights and cameras.
Key Specs
Who Will Love This
Watch collectors, car owners with older key fobs, and PC builders needing CMOS backup cells will find the format and count well matched.
Not Your Match When
Anyone running tactical flashlights or film cameras should reach for the Energizer 2CR5 or SureFire CR123A picks instead.
When a household runs a security camera, a smart sensor, and a couple of flashlights all keyed to CR123A cells, bulk buying stops being optional. The rapthor 40-pack delivers 1650mAh rated cells (mAh, or milliamp-hours, is the standard measure of how much energy a cell can deliver over time) with built-in PTC protection (a small internal fuse that limits current and heat if a cell short-circuits), aimed at high-drain gear that chews through batteries quickly.
You also get low self-discharge chemistry, which the maker rates for up to ten years of storage life on the shelf. Compare that to the Loopacell coin pick above, which targets tiny slots rather than high-output devices, and the difference in role is obvious.
A Few Highlights
- 40-cell count suits homes with several CR123A-powered devices running at once.
- 1650mAh rating supports extended runtime in motion sensors and flashlights.
- Built-in PTC layer helps guard against overcurrent and overheating events.
- Long shelf life keeps unused cells viable through years in a drawer.
Trade Offs
- Bulk format demands real storage space and a labeled bin to stay organized.
- Single-use chemistry means spent cells head to recycling rather than a charger.
The Right Fit
Households running multiple high-drain CR123A devices, or anyone who wants a long-term stash without reordering often.
Reach For A Different Pick When
Owners of a single flashlight who only need a spare or two will find the SureFire CR123A 12-Pack less wasteful.
The Energizer 123 2-Pack is the mainstream default for most households. It powers digital cameras, flashlights, and a range of smart-home devices with stable 3V output. The pack size keeps spares on hand without committing to bulk storage.
Compared with the single-cell pick at the top of this list, the 2-pack trims the per-cell cost while still fitting a small drawer. Versus the 40-cell rapthor bulk option above, the trade-off is straightforward: this one favors households running two or three devices over stockpilers.
Noteworthy Benefits
- Wide device compatibility across cameras, flashlights, and sensors.
- Two-cell format suits homes that cycle through one device at a time.
- Trusted brand backing for shoppers who want a familiar label.
Small Caveats
- Pack count drops fast in homes running several CR123A gadgets.
- Per-cell cost beats the single-pack but still trails the 40-count bulk buy.
Perfect Match For
Camera owners and casual flashlight users who want a reliable brand-name replacement without buying in bulk.
A Better Fit Elsewhere
Anyone running multiple security sensors should consider the rapthor 40-pack for fewer reorders.
Streamlight makes flashlights built around CR123A cells, so the brand’s own 85175 replacement pack sits naturally in the same drawer. The cells are non-rechargeable lithium with a 1400mAh nominal capacity, designed to deliver consistent output across film and digital camera use as well as Streamlight’s tactical line.
For shoppers loyal to Streamlight gear, the fit is obvious: same maker, same chemistry, no guessing. If your flashlight is from another brand, the Energizer 123 2-Pack or SureFire 12-Pack covers the same chemistry with more flexible sourcing.
Well-Handled Touches
- Native fit for Streamlight flashlights removes compatibility guesswork.
- Stable output suits both digital camera and high-output light use.
- Two-cell pack keeps a working spare on hand during long trips.
Points To Note
- Brand-matched value assumes Streamlight ownership first.
- Lower capacity rating than some bulk aftermarket cells on longer missions.

Swap It Out When
Households running several brands of flashlight will find the Energizer EL123BP-4 4-Pack more flexible.
The 9V form factor shows up in smoke alarms, carbon monoxide detectors, and a few pro audio devices. Energizer’s Ultimate Lithium 9V aims at exactly those roles, with a wide operating range that handles attic heat and unheated basement cold without losing output. The lightweight cell also reduces strain on wall-mounted detectors over years of service.
Unlike the CR123A cells above, this one fills a different niche entirely: low-drain safety devices that sit idle for months. You may find the per-cell cost higher than alkaline, but the trade is years of standby without the slow self-discharge that drags alkalics down.
A Favorable Mix
- Wide temperature tolerance suits smoke alarms in attics or unheated spaces.
- Lightweight 9V reduces strain on wall-mounted detectors over time.
- Multi-year storage life fits safety devices that rarely get touched.
Honest Caveats
- Per-cell cost runs higher than alkaline 9V alternatives for the same slot.
- Not a fit for any device expecting a CR123A or AA cell format.
Made For
Homeowners with smoke and CO detectors who want a long-interval replacement schedule.
Where Another Pick Suits Better
Anyone powering cameras or flashlights should stay with the CR123A-focused picks in this lineup.
The 2CR5 is a specialty 6V cell that powers a handful of older film and digital cameras. Energizer ships a single-pack replacement rated at 1500mAh, sized to fit camera battery compartments that won’t accept the cylindrical CR123A cells elsewhere on this list. The compact form factor (roughly 45 x 34 x 17mm) is the only practical option for those camera bodies.
Vintage camera shooters keep one or two on hand because the format is rare and a dead 2CR5 ends a shoot fast. Anyone shooting modern gear should stay with the CR123A picks above.
Where It Excels
- Direct fit for cameras that require the 2CR5 form factor.
- 1500mAh rating supports extended shooting sessions on a single cell.
- Single-pack format suits owners who only need occasional replacements.
A Few Limitations
- Niche format limits usefulness outside specific camera bodies.
- Higher per-cell cost than common CR123A picks for the same spend.
Quick Facts
Whose Shelf It Belongs On
Vintage film camera owners and shooters with select digital bodies that require the 2CR5 form factor.
Skip It When
Modern camera and flashlight owners should reach for the Energizer 123 or SureFire CR123A picks.
The Energizer EL123APB-2 leans into its photo-cell heritage, with the maker pointing toward film cameras, high-end flashlights, and certain medical devices. The 3V lithium chemistry delivers consistent output across temperature shifts, and the 2-pack format strikes a middle ground between single-cell trials and full bulk buys.
For someone who shoots film occasionally and keeps a tactical flashlight by the door, this pack covers both habits. Compared with the Streamlight 85175 above, this option isn’t tied to one flashlight brand, so it travels between devices more easily.
The Value In It
- Cross-device compatibility between cameras, flashlights, and select medical tools.
- Stable output across seasonal temperature changes.
- Two-cell pack balances spare coverage without bulk storage.
Points To Keep In Mind
- Pack count runs thin for households with several CR123A gadgets running at once.
- Some aftermarket cells advertise higher mAh ratings at similar pack sizes.
Right Fit For
Photo enthusiasts and flashlight owners who want a flexible, brand-name 3V lithium cell that moves between devices.
Consider Something Else When
Anyone needing more than a handful of replacements should consider the rapthor 40-pack.
SureFire built its reputation on high-output flashlights, and the SF123A cells are tuned for that exact demand. The 12-pack suits users who cycle through cells during long shifts, training sessions, or extended outdoor trips. A wide temperature tolerance means the cells keep working on cold trailheads and hot summer jobsites alike.
For tactical flashlight fans, the brand match is the headline: same maker, same engineering target, predictable runtime. For mixed households, the Energizer 123 2-Pack above offers more flexibility across non-tactical devices.
What Works In Its Favor
- Optimized for high-drain tactical flashlight use.
- Wide temperature tolerance handles outdoor conditions across seasons.
- Long shelf life keeps spare cells viable through storage gaps.
Where It May Fall Short
- Non-returnable listing limits options if cells arrive with unexpected issues.
- Premium positioning costs more per cell than mainstream 2-pack options.

Another Choice May Suit
General households running cameras and small electronics will find the Energizer 123 2-Pack more practical.
The Energizer EL123BP-4 lands at the sweet spot for households juggling a few CR123A devices at once. Four cells keep cameras, door sensors, and a flashlight covered without jumping straight to bulk. The lithium chemistry holds voltage through long standby periods, so a spare in the junk drawer stays ready.
For mixed households, this 4-pack sits between the 2-pack above and the 40-cell bulk buy further up the list. It also doubles as a backup reserve for anyone who normally relies on the single-cell pick at number one.
Benefits That Matter
- Four-cell count covers several devices at once without bulk storage.
- Lithium chemistry maintains output through long standby stretches.
- Familiar brand cuts the learning curve for first-time lithium buyers.
Practical Considerations
- Pack count still trails the rapthor 40-pack for high-volume households.
- Cells are single-use, so spent batteries head to recycling, not a charger.
Perfect Match For
Multi-device households that want a flexible count and a trusted label without buying in bulk.
Wrong Turns To Avoid
Anyone running several security cameras or tactical lights should consider the rapthor 40-pack for fewer reorders.
Matching The Right Cell To Your Gear
Chemistry and form factor come first. Lithium 123, CR123A, and 2CR5 cells share a lithium base but differ in voltage and physical size. Matching the exact spec on the original battery matters, since a 6V 2CR5 will not substitute for a 3V CR123A in a flashlight. Coin formats like the CR2330 fill their own niche in watches and key fobs.
Capacity ratings tell you how long a cell will last under load. A 1650mAh CR123A generally outlasts a 1400mAh unit in high-drain lights, though actual runtime depends on the device. For low-drain safety devices, capacity matters less than shelf life and temperature tolerance.
Pack count drives how often you reorder. A 2-pack fits casual camera use, while a 12-pack or 40-pack makes sense for households running several devices or professionals who burn through cells. Buying slightly more than you need today often beats scrambling for a single replacement mid-task.
Storage conditions affect shelf life more than most shoppers realize. Cells stored in a hot garage or damp basement lose capacity faster than spares kept in a climate-controlled drawer. Lithium cells handle temperature swings better than alkaline, but a cool, dry spot still extends their usable life.
Key Considerations Across These Picks
Mistakes Worth Dodging
Mixing chemistries in the same device is a common slip. A lithium 123 cell and a rechargeable RCR123A look identical but deliver different voltages, and swapping them can damage sensitive gear. Stick with the chemistry the device maker specifies, and treat any “compatible” label as a prompt to verify before installing.
Buying the cheapest bulk pack without checking the mAh rating is another trap. Two 40-packs at similar pack sizes can deliver noticeably different runtimes if the capacity ratings diverge. Capacity, not just count, is what determines how long your devices actually run.
When Paying More Pays Off
Premium picks like the SureFire 12-Pack and the Energizer Ultimate Lithium 9V cost more per cell, but the trade shows up in longevity and consistency. For high-drain tactical lights, the extra runtime per cell means fewer swaps in the field. For safety devices, the longer shelf life reduces how often you climb a ladder to replace batteries. The honest read is that premium cells pay off when downtime or reliability matters more than upfront cost.
Frequently Asked Questions
How long does a 213 lithium battery last in storage?
Most lithium 123 cells are rated for around ten years of shelf life when stored in a cool, dry spot. Heat and humidity shorten that window, so a climate-controlled drawer beats a garage shelf.
Can I use rechargeable batteries in devices designed for 213 lithium cells?
Only if the device specifically lists support for RCR123A or equivalent rechargeable chemistries. The voltages differ, and using the wrong type can damage both the cell and the device.
Are all 213 lithium batteries the same size?
No. The 123, CR123A, 2CR5, and coin formats all share a lithium base but differ in dimensions and voltage. Always check the original cell label before ordering a replacement.
What is the difference between CR123A and 123 lithium batteries?
In practice, the terms refer to the same 3V lithium chemistry and form factor. Manufacturers use both labels interchangeably, so either should fit a device listing either spec.
Why do lithium batteries cost more than alkaline?
Lithium cells hold voltage longer, weigh less, and perform across wider temperature ranges than alkalines. The higher upfront cost reflects the more demanding chemistry and longer service life.
The Takeaway
The right 213 lithium battery comes down to matching format, capacity, and pack size to how many devices you actually run. A single Energizer 123 cell suits a quick test, while a 4-pack covers mixed households. Bulk formats make sense for high-drain setups, and specialty picks like the 2CR5 or 9V fill roles the cylindrical CR123A cells cannot. Match the cell to the device, keep spares in a cool drawer, and the next dead battery becomes a minor swap rather than a ruined afternoon.
