Energizer Watch Battery Tester

Long lasting battery like the energizer battery.

Great battery tester, Love it.

I like this tester...

I have worked on portable instruments for over 27 years and this is the best battery tester I have found.

I like energizer bateries because they last. I have tried other brands and its not the same.

Have tried other brands, just seems to be that Energizer's last longer, than other brands.

This is my second battery tester and it is indispensable. I have a ton of battery operated devices and I have been able to see which batteries work best...

Love this tester!

I recently purchased the Energizer LR44 Alkaline Button Cell Battery for a digital thermometer and a few other small devices, and I’m thoroughly impressed. These batteries have exceeded my expectations in terms of longevity—they’ve powered my devices for much longer than expected, especially compared to other brands. The power delivery is stable and reliable, ensuring consistent performance without any unexpected power drops. Additionally, the LR44 size fits a wide range of devices, making it a versatile option. I’m very satisfied with this purchase and will continue to use Energizer for my battery needs!

Couple of weeks ago I purchased a Youngnuo N1410 LED light and used energizer lithium batteries that didn't last for about a day so I purchased a Watson NP 970 High capacity Lithium ion battery, the problem was there was no charger included, I had to do a search and found this little baby and it fit right in with my battery, BUT a word of caution you can not leave the battery on this charger for no more than two hours for the charger will heat up quickly, over all this was a good purchase.
