Energizer Zero Mercury Alkaline Batteries A23 2 ea

These are for my doorbell bellpush. The last one lasted a year (and yes; we do have visitors!) so these two will last me a while. I've never been disappointed with Energizer batteries and these didn't break the bank.

Fantastic!!!I could not believe they packed a whole 12, Yes 12!!! volts into such a small item and not only that there were TWO of them!!!Despite the lack of clear instructions I was able to install this product which I purchased as a direct replacement for the previous one and I must say I was absolutely gobsmacked at the performance increase on the previous one, I pressed the doorbell and my world was instantly transformed into an audio extravaganza not only did my doorbell go "ding" but it added a "dong" which in my humble opinion is a full 100% improvement on the simple "ding". I have tested this product extensively since I eagerly received it in all of its blister packed majesty and I can state without fear of contradiction that not once in all of this time have I had a single missed "dong", every single instance has been met with a resounding "ding dong". to say that this product is a life changer is an understatement. would gladly have paid ten times the asking price for such amazing service.

Purchased for doorbell and they work well. I thought price was good and they came very quickly.

Great batteries

Battery works well

Battery pack was delivered quickly and the product is working fine. I only needed one, but bought a pack of two so I had a spare for replacement.However, I couldn't see a use by date on the packet - and only found one by peeling back a label somebody had slyly applied on the back,which revealed October 2025. That's only a little over a year, and the dead battery I replaced lasted more than five years...go figure. This must be old stock.

Quick delivery and exactly what was required.

If you need A23 batteries then these are worth consideration. Last well.
