Duracell 21/23 12V Alkaline Battery, 4 Count Pack, 21/23 12 Volt Alkaline Battery, Long-Lasting for Key Fobs, Car Alarms, GPS Trackers, and More

Though these initially got lost by the shipper, I did eventually get them. The price is fantastic - especially when you consider that Batteries Plus and other local shops wanted $6 per battery.

Used in garage door opener remote. Works great.

We have several remote-control units which require this type of battery. One had a dead battery, so I replaced it with one of these -- which solved the immediate problem. Of course theres no way to tell, after only a few days, how long they will last, so the specific ratings suggested are meaningless.

Good price

Used it for my garage door opener remote.

Easy to order when not available locally. Other order options were more expensive for two than the price of these 4. Amazon came through again.

Didn’t want to mess looking locally for this size battery. Duracell’s turned up on Amazon with next day delivery at a fair price. So buy now was an easy decision.

Exact replacement for two ceiling fan remotes that had been giving me trouble. Replaced battery in each and they work like new. Get a pack for your application. They work.

These batteries were ordered for my ceiling fan’s remote control. They arrived quickly and we’re perfect

Batteries were only good for less than four years, most are 10 years.
