The 1.5V AA Panasonic Evolta Alkaline batteries are supposedly the best primary batteries of the Alkaline type that Panasonic has. Panasonic claims that these Evolta series offer exceptional performance in low, mid and high drain products, but we need to check and confirm for ourselves before agreeing to that claim. We have already tested Panasonic Pro Power Alkaline batteries and they were performing among the top ones, so we are starting with high expectation from the Evolta as well, but let us see what capacity they can actually deliver. The batteries we tested here were with an expiration date of 02-2019.

We have started the test of the 1.5V AA Panasonic Evolta Alkaline batteries as we normally do with a low constant current discharge rate of 0.1A and the result we got was 2342 mAh as capacity. With this result the Evolta goes somewhere in the middle of our Top 10 Alkaline batteries for low load applications and rates, but is still less than the Panasonic Pro Power. Increasing the constant current load to 0.2A and the performance of the Evolta goes below the top 10, the same goes for the higher load of 0.5A and only at the 1.0A test it barely manages to get into the bottom of the Top 10. So the conclusion is that although the Evolta is performing quite well at low loads, but it does not handle as well with higher constant current loads as our tests are showing. There are simply better alternatives to the Panasonic Evolta Alkaline batteries.

The performance of the 1.5V AA Panasonic Evolta Alkaline batteries in our tests:

– 2342 mAh at 0.1A load
– 1641 mAh at 0.2A load
– 850 mAh at 0.5A load
– 478 mAh at 1.0A load

– 2.946 Wh at 0.1A load
– 2.010 Wh at 0.2A load
– 1.011 Wh at 0.5A load
– 0.549 Wh at 1.0A load
