1.0 out of 5 stars Out of date
By Marcus P on 28 August 2021
I bought these to replace the battery in my car key fob since I started getting a key not detected message. Unfortunately, they are out of date. They have an expiry date of December 2020 and I am writing this review at the end of August 2021. I didn't discover this until after I had opened the packet and installed the battery. I still get the key not detected message in my car so I have no idea if I have a sensor problem or a battery problem. I will now have buy more batteries (in date) to find out.

If you do decide to buy these batteries, before you open the pack check out the expiry date on the back.

1.0 out of 5 stars 50% less power more like...
By Paradoxically on 21 August 2019
This is the 2nd order of these batteries (abouttthree months apart). I use them in my Polar H10 chest trap for phys. Polar quote something like 400 hours plus so I should have cottoned on with the first order when my Garmin began telling me battery level was low after ten days (that'll be 15 hours then). I've since bought Amazon's top selling battery tester which shows all 8 BRAND NEW cells from my 2nd order to be either flat or as close to flat to not matter.

Sooo. We either have a) snidey batteries, b) counterfeit batteries, or c) batteries that have been kept in conditions specifically designed to run the power down. Seriously, if you order these then spend a couple of quid on the tester (it does aa, aaa etc). You'll be doing yourself a favour and helping other customers out by highlighting naff batteries like these...
