1.5V AA Kodak Max Alkaline Battery Tests

5, Dec 2013

1-5v-aa-kodak-max-alkaline-battery

The 1.5V AA Kodak Max Alkaline batteries are the standard Alkaline batteries from Kodak that we tested here. We were actually quite interested to see how these batteries will perform considering the fact that Kodak is a well know name in the photography world. The batteries we tested were with an expiration date of 07-2017 and we could not find any official information about their shelf life, but it is most likely 5 years.

We have started the test of the 1.5V AA Kodak Max Alkaline batteries as we normally do with a low constant current discharge rate of 0.1A and the result we got was 2084 mAh as capacity – decent performance at low loads, but nothing spectacular here. Increasing the constant current load to 0.2A the batteries still do quite good at 1529 mAh, however going with higher loads of 0.5A the useable capacity we got was not that good. And at the 1.0A test we managed to get only about 45 mAh before reaching the cut-off voltage, clearly showing that these Kodak batteries were not designed to handle well higher loads, though they perform at about average level with low loads.

The performance of the 1.5V AA Kodak Max Alkaline batteries in our tests:

– 2084 mAh at 0.1A load
– 1529 mAh at 0.2A load
– 481 mAh at 0.5A load
– 45 mAh at 1.0A load

– 2.512 Wh at 0.1A load
– 1.780 Wh at 0.2A load
– 0.535 Wh at 0.5A load
– 0.048 Wh at 1.0A load

1.5V AA Panasonic Evolta Alkaline Battery Tests

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

1.5V AA Verbatim Premium Alkaline Battery Tests

The 1.5V AA Verbatim Premium Alkaline batteries are the only standard AA size Alkaline batteries offered by Verbatim, even though they are labeled as Premium there is no regular version available. The expiration date on the batteries we’ve tested was 06-2017 and even though we could not find a shelf live cited, we can safely assume something like 5 years for these batteries.


1-5v-aa-verbatim-premium-alkaline-battery-capacity

We have started the test of the 1.5V AA Verbatim Premium Alkaline batteries as we normally do with a low constant current discharge rate of 0.1A and the result we got was 2166 mAh as capacity – a good result for low load applications, though far from the best ones we’ve seen from AA size. Increasing the load ot 0.2A we still get a decent performance, but going higher than that at 0.5A and 1.0A we can see that these batteries are not performing that well, meaning they are not the wisest choice for high load applications.

The performance of the 1.5V AA Verbatim Premium Alkaline batteries in our tests:

– 2166 mAh at 0.1A load
– 1527 mAh at 0.2A load
– 613 mAh at 0.5A load
– 306 mAh at 1.0A load

– 2.626 Wh at 0.1A load
– 1.797 Wh at 0.2A load
– 0.674 Wh at 0.5A load
– 0.329 Wh at 1.0A load
