These CR123A lithium batteries stand out as a low-cost way to stock up on a size used in smart locks, smoke detectors, older flashlights, security cameras, flashes, and wireless doorbells. The coupon brought the six pack to under five dollars with tax for some orders, which is far below local retail pricing. The brand is also recognized in Asia. The main caution is that rechargeable substitutes are not always a direct replacement, since 3.7 volt 16340 cells can cause problems in some devices, especially pairs.

  • Homeowners with smart locks that burn through CR123A cells, because these batteries are used in August/Yale locks and rechargeable versions can drain quickly.

  • People replacing batteries in older flashlights, because some models use CR123A cells in pairs or with a spacer and the size still fits those devices.

  • Households stocking smoke detectors or wireless security gear, because this size is used in smoke detectors, security cameras, wireless doorbells, and monitors.

  • People expecting rechargeable 16340 cells to replace these everywhere, because 3.7-volt rechargeables can cause problems in devices designed for 3.0-volt CR123A batteries.

  • Shoppers who need a battery that is definitely ready to use, because one received pack was reported as dead.

  • Buyers counting on Subscribe & Save savings, because the discount did not apply and the total stayed near the listed price with tax.

Nice find, thanks OP! Couldn't get S&S to stack but coupon code worked great. I use these for an August/Yale smart lock. Sadly rechargeable versions seems to drain wicked fast.

The CR123a is the size. I have a couple older flashlights that use these in pairs or a single 18650 (supposedly - though may need a spacer). I haven't seen them used as much as they used to be - at least in flashlights. Other use cases probably still use them.

They finally came out with rechargables in this size, I switched to them and never looked back. Before that I used a ton of them for my electronic locks. This is a decent price but rechargables are the way to go in the long run.

Security cameras, flashes, wireless doorbells of certain brands, wireless monitors, kids electronics, and a myriad of other random wireless electronics that should use rechargeable batteries but don't because they are too cheap to install a 50 cent charging port and charging circuit in their device.

Really good deal! Timing is everything. I ordered a different brand for $12+ and they arrived yesterday. I used them so can't return. Bought these anyway. My smart lock drains these quickly. ThanksOP.

16340s are NOT a total solution. They'll work for most but not all applications.

16340s (Li-Ion rechargeables in identical size) are 3.7 volts, whereas these are 3.0 volts. Most devices have no problem with this, but some have a big problem, especially when it's two of them - 7.4 volts vs. 6.0 volts.

Just ordered them, less than $5 with coupon and tax. Hi Watt is a recognized brand in Asia. I remember Hi Watt alkalines coming with toys when I was a kid (1980s).
