The 1.5V AA Toshiba E-Power batteries are Carbon-Zinc primary batteries and are the third model in Toshiba’s line of such batteries. According to the manufacturer these batteries are supposed to provide 25% improved performance vs Heavy Duty line and while we still haven’t tested the standard 1.5V AA Toshiba Heavy Duty batteries, we have tested the Super Heavy Duty model, so we could compare these to the E-Power series of Carbon-Zinc products. Just a reminder, the Zinc batteries do offer shorter shelf life and lower capacity and are not suitable for high load applications as compared to the Alkaline primary batteries. The Toshiba E-Power batteries we tested here were with an expiration date 05-2015.

Time for the tests to start for the 1.5V AA Toshiba E-Power batteries beginning with a low constant current discharge rate of 0.1A and the result we got was 731 mAh as capacity. This is a decent result for a Carbon-Zinc batteries, but compared to the Toshiba Super Heavy Duty batteries the E-Power does provide less useable capacity. Increasing the load to 0.2A and the E-Power still does pretty good, though at 0.5A the performance is not that good already and 1.0A proves to be too much. As expected these batteries do perform well, but are nothing special even for Zinc batteries. They are suitable for low load applications, but not for high load ones where you should definitely consider either good Alkaline batteries or even NiMH batteries.

The performance of the 1.5V AA Toshiba E-Power batteries in our tests:

– 731 mAh at 0.1A load
– 516 mAh at 0.2A load
– 199 mAh at 0.5A load
– 36 mAh at 1.0A load

– 0.874 Wh at 0.1A load
– 0.589 Wh at 0.2A load
– 0.207 Wh at 0.5A load
– 0.036 Wh at 1.0A load

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.


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

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
