New 20 Pk A23 23A 21/23 MN21 12v Batteries

This product (batteries) are awesome, long lasting, great price and quick delivery, I will continue buying them.

I purchased these batteries for some of my fish bite alarms and so far they are working great and are lasting a long time.

Have to replace these in alarm sensors at least every 6 months, usually sooner. That's true even if the sensors are never or hardly ever tripped. At least they are not expensive.

batteries are junk. do not buy them. they came in with the charge depleted. i ordered the 10 pack and 9 out of the 10 batteries had no charge and the one that had decent charge lasted about15 seconds. I don't recommend. dont waste your money

Great price for 20 I even ordered a second batch because I had never heard of this battery before before until I bought several products from a shady vendor , Which used this battery

This product is a great deal. 20 batteries in all. Unfortunately, the first packaged I open and the very first battery I put in th remote did not work. The second one did so I won’t take the effort to return the product because possibly one battery did not work.

Arrived ptomptly and a great value for all those fan remotes.

I bought some of these 6 months ago for my alarm system. I keep a record of installation dates for timely replacement purposes. Those I installed have not lasted as long as brands I have used previously. I will not purchase these again.
