More Details On Our Top Picks
The six-pack DL123AB has anchored Duracell’s photo lineup for years, and it earns its reputation through dependable output rather than flashy packaging. Photographers shooting in cold weather benefit from its wide operating range, where alkaline cells tend to fade well before the shoot ends. Energy density is a real point of pride here, delivering roughly four times the runtime of an alkaline counterpart under similar draw.
This format stays relevant for anyone running older film cameras, laser sights, or medical devices still designed around the original 123 cell layout. Compared with the two-count CR123A we’ll cover next, this six-pack rewards households that rotate through cells across multiple gadgets.
Where It Excels
- Six-cell format keeps spares on hand for multi-device households
- Wide operating temperature range suits outdoor photography in cold conditions
- High energy density means fewer swaps during long shooting sessions
- Long-established DL123AB spec, broadly compatible with legacy equipment
Worth Noting
- Branded as a “photo” cell, so packaging reads camera-specific even when used elsewhere
- No stated multi-decade shelf claim on the retail label
Key Specs
Made For
Photographers and households running several legacy 123-format gadgets who want a known-good spare set.
Consider Something Else When
You mainly run Ring or Nest cameras and want a published 10-year storage guarantee; the Duracell CR123A two-count carries that claim directly on the packaging.
This two-count is the most security-focused option on the list, and its packaging spells that out plainly. You get a published 10-year storage guarantee, which matters when you’re tucking spare cells into a kitchen drawer for the next time a window sensor chirps at 2 a.m. High-drain devices like Ring, Nest, and Arlo cameras draw down alkalines fast, but lithium chemistry here holds its voltage curve under continuous load.
Where the six-pack above leans toward photography, this one leans toward home automation and tactical flashlights. Two cells match the typical device requirement, so there’s little wasted inventory once you crack the package.
Practical Advantages
- Ten-year storage guarantee printed on the package
- Designed around high-drain cameras and tactical lights
- Works across Ring, Nest Cam, and Arlo ecosystems
- Two-cell pack matches the most common device requirement
Trade Offs
- Smaller pack means more frequent repurchase for households running many devices
- Premium per-cell pricing versus bulk Hillflower options
Right Fit For
Smart-home households with a few security cameras or alarm sensors who value a published shelf-life claim.
Look Elsewhere When
You stock emergency kits in bulk; the POWEROWL 12-count delivers four times the cells for similar total spend.
The DL123ABU sits between the photo-focused six-pack and the security-focused two-count, leaning on Duralock Power Preserve technology to keep cells viable in storage. That detail matters when the cells live in a drawer for two years between uses, because nothing’s worse than swapping in a “fresh” battery only to find it reads half-dead.
Its wide operating temperature range covers both unheated garages and outdoor security cameras exposed to summer sun. Compared with the higher-volume POWEROWL pack we’ll cover next, this is the smaller, brand-name option for shoppers who’d rather buy four cells across two purchases than twelve from an unfamiliar label.
Points In Its Favor
- Duralock Power Preserve chemistry targets long shelf storage
- Tolerates wide temperature swings from cold garages to outdoor mounts
- Common pick for home security camera systems and digital cameras
- Compact two-pack avoids clutter in drawer storage
Things To Consider
- Per-cell pricing climbs compared with bulk packs
- Ten-year shelf claim is not explicitly printed on this SKU’s retail packaging
Best Suited To
Shoppers who want a familiar brand in small quantities for occasional-use devices.
Skip It When
You need dozens of cells for an alarm install job; the Hillflower 100-count is built for exactly that workload.
POWEROWL positions this 12-pack as a high-capacity answer for households that cycle through cells faster than the small packs can keep up. Each unit is date-coded individually, so you know exactly when the line was packaged rather than guessing based on a printed date. That matters for outage planning: you want hurricane-season spares that haven’t already spent two years aging in a warehouse.
Where the Duracell packs above serve two- and six-cell needs, this is the entry-level bulk tier. For shoppers running several cameras, a tactical flashlight collection, and motion sensors, twelve cells stretch across all of them with spares left over.
Positive Takeaways
- Twelve cells cover multi-device households in a single purchase
- Individually date-coded packaging aids rotation planning
- Built-in multiple protections per cell for safer discharging
- Ten-year storage guarantee listed in product documentation
Points To Note
- Less familiar brand compared with Duracell’s household recognition
- Cells ship as a pack-of-two configuration, so packaging isn’t a single sealed brick
Whose Shelf It Belongs On
Smart-home power users and small-business owners running eight or more CR123A devices who rotate spares regularly.
Reach For A Different Pick When
You only need two or three cells for a single camera; the Duracell two-count is more cost-appropriate at that scale.
Hillflower’s 10-pack sits at the bridge between brand-name two-packs and contractor-grade bulk. The compatibility list reads like a CR123A compatibility chart: 123A, DL123A, PL123A, and CR17345 cross-references all spelled out, which is useful when the device manual mentions a part number you’ve never seen before. For shopkeepers stocking a parts bin or homeowners tackling a single alarm panel, ten cells is a manageable inventory.
Compared with the larger Hillflower SKUs that follow, this one is the right size for trying the brand without committing to a hundred-cell brick. You get a sense of cell consistency without over-investing.
Benefits That Matter
- Explicit cross-reference for 123A, DL123A, PL123A, CR17345 part numbers
- Mid-volume pack avoids overcommitment for first-time buyers
- Useful for alarm panels, sensors, and PC peripherals
- Lower per-cell cost than name-brand equivalents
Small Caveats
- Less brand-name recognition than Duracell or mainstream competitors
- Storage guarantee details vary by batch and aren’t always printed on packaging
Perfect Match For
DIYers and homeowners replacing cells across an alarm panel or a cluster of remote sensors.
Swap It Out When
You’re a contractor who installs these weekly; the Hillflower 100-count keeps the per-cell cost meaningfully lower.
This is the SKU where Hillflower stops competing for household drawers and starts competing for installation jobs. A hundred-pack is the kind of stock a security-system installer pulls from a work van, and the part-number cross-reference list (123A, DL123A, PL123A, CR17345) covers the cell spec nearly every alarm panel calls for.
Buying a hundred cells up front demands realistic usage planning. For most homeowners, this is overkill. For anyone running an alarm company, property-management office, or short-term rental operation, the per-cell math beats anything else on this list by a meaningful margin.
Strong Points
- Lowest per-cell cost on the entire shortlist
- Designed around installer and contractor usage volumes
- Broad part-number compatibility for mixed device fleets
Points To Keep In Mind
- Hundred cells exceed typical household rotation windows
- Requires organized storage so older cells get used before newer ones
Built With In Mind
Contractors, property managers, and small alarm-installation outfits burning through dozens of cells monthly.
Not Your Match When
You just need to replace two cells in a smoke detector; the Duracell two-count covers that for far less.
The “long duration” wording on this SKU flags a chemistry variant aimed at devices that draw small but constant current for years. Think of smoke detectors mounted on vaulted ceilings, attic-mounted motion sensors, or backup sensors in second properties. Every climb up a ladder to swap a cell is friction, so a longer-lasting cell pays off in fewer service trips.
Compared with the standard 100-pack above, the trade-off is usually a small per-cell premium in exchange for that extended runtime profile. For anyone stocking cells for hard-to-reach devices, the premium is genuinely worth it.
Noteworthy Benefits
- Long-duration chemistry targets low-draw but constant-load devices
- Reduces ladder trips for ceiling-mounted detectors
- Same broad part-number compatibility as standard Hillflower cells
Potential Drawbacks
- Higher per-cell cost than the standard 100-pack
- Overkill for devices you actively cycle through weekly
Who Should Grab It
Property managers and homeowners with detectors mounted in awkward or high places who want fewer service visits.
A Better Fit Elsewhere
You mostly power tactical flashlights you use every weekend; the POWEROWL 12-pack is the better match for actively cycled gear.
Twenty cells of long-duration chemistry hits a sweet spot that the larger packs miss. It’s enough to outfit a small office or a multi-story home without forcing a hundred-cell commitment, and the long-duration formulation suits the typical CR123A use case (low-draw detectors and remotes) better than a standard cell would.
For shoppers who looked at the standard 100-pack and felt it was too much inventory, this 20-count delivers the same chemistry advantage at a more digestible volume. The honest read is that mid-size households rarely need more than this.
The Good Stuff
- Long-duration chemistry in a manageable mid-volume pack
- Suits small offices and multi-room homes
- Covers roughly a decade of detector replacements for most households
A Few Limitations
- Per-cell premium over the standard 100-pack
- Less widely distributed than mainstream brand-name equivalents
Who Will Love This
Homeowners and small-office managers who want long-duration cells in a pack that won’t gather dust for ten years.
Where Another Pick Suits Better
You only have one smoke detector to power; the Duracell two-count keeps the cost-per-swap much lower.
Five cells is the smallest sensible multipack on this list, and it serves shoppers who just want a few spares without committing to inventory. Long-duration chemistry in such a small pack is unusual; most starter multipacks ship standard cells. That alone makes this SKU worth a look for anyone with a single hard-to-reach detector they don’t want to service again soon.
Compared with the brand-name two-packs earlier, the trade-off is brand familiarity versus cell count. For a brand-new CR123A shopper, five cells leave room for mistakes and an extra spare without a large spend.
Real Benefits
- Smallest viable multipack for first-time CR123A shoppers
- Long-duration chemistry in a starter-friendly count
- Useful as a “just-in-case” drawer stash
Honest Caveats
- Per-cell cost is the highest on the entire list
- Not enough cells for a multi-device household
Perfect Match For
First-time CR123A shoppers who just want enough spares to cover a single detector for years.
Consider Something Else When
You run several cameras and sensors; the POWEROWL 12-pack gives you room to grow at a similar per-cell price.
What Matters Most Before Choosing a 123a Battery
Match the Chemistry to the Device
CR123A cells run on lithium chemistry, which delivers a stable 3V output across most of the discharge cycle. That stability matters in cameras and alarm sensors, where voltage sag triggers low-battery warnings well before the cell is truly dead. Alkaline replacements simply don’t hold their voltage under the same continuous draw, which is why lithium has become the standard for any device that watches your home unattended.
Count Cells Before You Buy
The format naming can mislead shoppers, since CR123A, 123A, DL123A, PL123A, and CR17345 all reference the same physical cell with subtle manufacturer differences. Cross-reference your device manual’s part number against the product listing before committing to a hundred-pack; nothing’s worse than a bulk order that doesn’t fit the gear you actually own.
Buy for Storage Life, Not Just Capacity
Lithium cells self-discharge slowly, which is why premium SKUs advertise 10-year storage guarantees. A cell you buy today might live in a drawer until the next power outage or hurricane season, so shelf-life claims deserve as much weight as runtime claims. Look for individually date-coded packaging if you plan to stockpile.
Think About Device Access
Smoke detectors on vaulted ceilings and attic-mounted sensors create real service friction. Long-duration cells cost more per unit but save ladder trips, so the upgrade often pays for itself through reduced maintenance time. For gear you cycle through weekly, standard chemistry keeps the cost-per-use honest.
Common Shopping Slip Ups and What the Higher Tier Buys
Common Shopping Slip Ups
Buying alkalines instead of lithium is the most frequent misstep in this category, since some retailers still shelve AA-shaped cells near the CR123A section. Confusing the two formats ruins the cell and sometimes the device. Stocking cells without checking the part number on the device label is a close second; CR123A cross-references like DL123A and PL123A exist, but only because each manufacturer used its own label originally. Buying in quantities that exceed realistic rotation windows can leave you with cells aging past their useful life in a drawer.
What the Higher Tier Buys
Premium CR123A cells cost more because they hold tighter voltage tolerances, ship with longer storage guarantees, and use chemistries optimized for specific drain profiles. Long-duration variants stretch runtime in low-draw devices that would otherwise need annual swaps. Brand-name cells from Duracell typically include better-documented storage claims and tighter quality control, which is worth the premium for security-critical gear but less critical for occasional-use remotes.
Frequently Asked Questions
How long does a CR123A battery typically last in a security camera?
Most lithium CR123A cells power a typical home security camera for three to six months, depending on motion-activity volume and temperature conditions. Cold-weather mounting locations tend to shorten that window noticeably.
Are CR123A and 123A batteries the same thing?
Yes, CR123A and 123A refer to the same 3V lithium cell format, just with different manufacturer labeling conventions. Cross-reference part numbers like DL123A and PL123A against your device manual before ordering in bulk.
Can I substitute CR123A with rechargeable RCR123A cells?
RCR123A rechargeable cells share the same physical dimensions but typically deliver a slightly lower nominal voltage, around 3.7V, which can cause issues in devices calibrated for 3V primaries. Confirm your device manual supports rechargeable chemistry before substituting.
Is it worth buying CR123A batteries in bulk?
Bulk packs make sense for installers, property managers, and households running six or more CR123A devices. For households with only one or two devices, smaller packs avoid the risk of cells aging out before you use them.
How should I store spare CR123A batteries?
Keep spares in their original sealed packaging, in a cool, dry location away from direct sunlight. Avoid storing loose cells in a metal drawer where they can contact other batteries and discharge.
The Takeaway
The right CR123A battery depends on how many devices you run, how often you swap cells, and whether brand familiarity matters more than per-cell cost. Brand-name two-packs suit small security setups, mid-volume long-duration packs cover most homes, and contractor-grade bulk packs reward high-volume users. Pick the size that matches your rotation window, and you’ll spend less time on ladders and more time with working gear.
