1-5v-aa-agfaphoto-alkaline-power-battery

The 1.5V AA AgfaPhoto Alkaline Power batteries are from a German brand associated with Photography, though the batteries produced under that brand are a licensed product, nevertheless we are interested to see how well they will perform in our tests. According to AgfaPhoto their Alkaline batteries are supposed to offer long-lasting dependable power to thirsty everyday devices such as toys, torches, electronic games and more. The batteries we got for testing here were with an expiration date of 01-2016, so they are probably not so fresh with a possible shelf life of about 4-5 years as couldn’t find exact data about this.

Time for the tests to start for the 1.5V AA AgfaPhoto Alkaline Power batteries beginning with a low constant current discharge rate of 0.1A and the result we got was 2441 mAh as capacity is actually quite impressive considering that the batteries have probably been produced close to two years ago or possibly more even close to three years ago. This result is better than that of a more recently produced Duracell Copper Top battery and places the AgfaPhoto in about the middle of out Top 10 AA Alkaline batteries for load load applications. Thought the capacity we are getting from the batteries with increased loads is not that serious, probably due to the fact that they were not so freshly produced. Anyway, we are seeing really promising results here from the AgfaPhoto batteries and we are going to look for a newer production to repeat the test and see if we are going to get better results, but even with these batteries we still get quite good results in terms of usable capacity both for lower and higher load applications.

The performance of the 1.5V AA AgfaPhoto Alkaline Power batteries in our tests:

– 2441 mAh at 0.1A load
– 1753 mAh at 0.2A load
– 1024 mAh at 0.5A load
– 419 mAh at 1.0A load

– 2.995 Wh at 0.1A load
– 2.079 Wh at 0.2A load
– 1.166 Wh at 0.5A load
– 0.459 Wh at 1.0A load

1-5v-aa-philips-powerlife-alkaline-battery

The 1.5V AA Philips PowerLife Alkaline batteries are the first batteries from the company that we are testing, so we were quite interested to get a look at how they perform compared to others as Philips is a well known name in the consumer market. The batteries were with an expiration date of 04-2016 and the manufacturer’s quoted shelf life for these batteries is 5 years, meaning that they were produced in 2011, so the capacity we get could be slightly lower than that of fresher batteries that were produced at a later date.

We have started the test of the 1.5V AA Philips PowerLife Alkaline batteries as we normally do with a low constant current discharge rate of 0.1A and the result we got was 1986 mAh as capacity. Good level of performance that continues at 0.2A load, but the available capacity under higher loads as 0.5A and 1.0A is not that good, though these batteries still manage to perform decently. Apparently these Philips Alkaline batteries are intended mostly for applications not requiring too much power, and though they manage to provide some capacity in applications requiring more power, this is definitely not their strength.

The performance of the 1.5V AA Philips PowerLife Alkaline batteries in our tests:

– 1986 mAh at 0.1A load
– 1622 mAh at 0.2A load
– 563 mAh at 0.5A load
– 236 mAh at 1.0A load

– 2.425 Wh at 0.1A load
– 1.884 Wh at 0.2A load
– 0.650 Wh at 0.5A load
– 0.257 Wh at 1.0A load

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.


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

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
