A upkeep battery, the Panasonic Alkaline Power AAA series is designed for depression- to mid-drain uses, such as clocks and remote controls.

Relatively cheap to purchase, the problem with these batteries is that you tin get higher capacity versions for less, making these an option merely if you can’t find adept alternatives.


  • Middling capacity
  • Comparatively limited shelf life

It’s common to run across alkali metal batteries with a 10-year shelf life, but the Panasonic Alkali metal Ability AAA are rated for seven years only. That may non sound like much of a difference, simply if you buy in majority and batteries accept already been sat around for a while you lot may end upwards with some that you don’t get the most out of.

Panasonic doesn’t quote any capacity figures for these batteries, proverb simply that they’re designed for low- to mid-bleed uses only. To meet how well they did, I put them through my standard tests using an Ansmann Energy XC 3000.

First, I used the tester to measure the average starting voltage, which should ideally be 1.5V or higher; yet, the gear up of Panasonic Alkaline Power AAA batteries that I bought from Amazon measured simply ane.41V. Voltage drops rapidly in apply but, even and then, the starting voltage was a little off the platonic.

Next, my loftier drain examination runs at 600mAh (+/- 20%), standing until the voltage hits 0.94V. Initially, the Panasonic Alkaline Power AAA batteries returned a capacity of 260mAh, which is the least of all the AAA batteries that I’ve tested; they’re a long manner behind the Amazon Nuts Alkaline AAA.

I then requite batteries a couple of hours to absurd downwardly, re-running the test to measure whatever residual charge. With this second test, I managed to get some other 82mAh out of the batteries, giving me a full capacity of 341mAh. Over again, that’s the lowest overall capacity that I measured.

If you lot just need a ready of inexpensive batteries for low-drain utilise, then these volition practice the chore.

If you lot look around, you tin can get cheaper batteries with college capacities, suitable for a wider range of jobs.

Final Thoughts

Although relatively cheap, the Panasonic Alkaline Ability AAA fall behind the competition in my tests, and fall behind in terms of shelf life. Given that the Amazon Basics Alkali metal AAA batteries can be bought cheaper in bulk and did ameliorate in my tests, there’south piddling reason to buy these ones.
