1-5v-aaa-xcell-alkaline-battery

The 1.5V AAA Xcell Alkaline batteries are nothing special at first look and are not a popular or well known brand, so we took them for a spin to see how good they will perform in our tests, The particular batteries we are testing here were all marked with an expiration of 2017, no particular month mentioned so we can assume they have a shelf life of 4 years.


1-5v-aaa-xcell-alkaline-battery-capacity

Starting our test of the 1.5V AAA Xcell Alkaline batteries as usual with a low constant current discharge rate of 0.1A we have managed to get 893 mAh as capacity – a decent achievement, though a bit far from the highest result we’ve seen. Increasing the load to 0.2A, 0.3A and even at 0.5A the useable capacity we’ve got was still very decent. The interesting thing here is that the difference between the shown useable capacity at the higher test loads was with smaller gaps, indicating that these batteries are designed to handle well higher current loads. The Xcell Alkaline batteries seem to perform well, but are nothing special in terms of performance…

The performance of the 1.5V AAA Xcell Alkaline batteries in our tests:

– 893 mAh at 0.1A load
– 532 mAh at 0.2A load
– 400 mAh at 0.3A load
– 314 mAh at 0.5A load

– 1.072 Wh at 0.1A load
– 0.600 Wh at 0.2A load
– 0.450 Wh at 0.3A load
– 0.351 Wh at 0.5A load

1-5v-aaa-maxell-super-alkaline-battery

The 1.5V AAA Maxell Super Alkaline batteries are supposedly better than standard Alkaline batteries that Maxell makes and are intended for high-drain devices according to the company. The batteries we’ve had for testing were with an expiration date of 01-2017 meaning that the shelf life is at least 4 years, though we are not exactly sure when these batteries were produced so it might also be 5 years. Anyway, let us see how good these 1.5V AAA size Alkaline batteries from Maxell perform in terms of useable capacity in our tests…


1-5v-aaa-maxell-super-alkaline-battery-capacity

Starting our test of the 1.5V AAA Maxell Super Alkaline batteries as usual with a low constant current discharge rate of 0.1A we have managed to get 948 mAh as capacity and that is actually a very good result. Increasing the load to 0.2A and 0.3A the Maxell batteries do manage well, and even at 0.5A the useable capacity was still quite decent. In overall these Alkaline batteries seem to be doing quite well, but do not provide as much capacity as an Alkaline Duracell battery of the same type for example does (we use Duracell as a reference), so there is more to be desired.

The performance of the 1.5V AAA Maxell Super Alkaline batteries in our tests:

– 948 mAh at 0.1A load
– 572 mAh at 0.2A load
– 474 mAh at 0.3A load
– 253 mAh at 0.5A load

– 1.135 Wh at 0.1A load
– 0.675 Wh at 0.2A load
– 0.552 Wh at 0.3A load
– 0.282 Wh at 0.5A load

1-5v-aaa-varta-superlife-carbon-zinc-battery

The 1.5V AAA Varta Superlife batteries are of the Carbon Zinc type even though that fact is not marked anywhere on them. The batteries we have for testing here were with an expiration date of 03-2016, so they are supposedly offering a shelf life of 3 years as with most other Carbon Zinc batteries of this size. So what about their capacity, well as is the case with Carbon Zinc batteries you should not expect much, but let us see what capacity these batteries will show in our tests.


1-5v-aaa-varta-superlife-carbon-zinc-battery-capacity

We have started the test of the 1.5V AAA Varta Superlife Carbon Zinc batteries as usual with a low constant current discharge rate of 0.1A and the result we got was 372 mAh as capacity. Increasing the load to 0.2A and 0.3A the Varta batteries still did pretty good and even at 0.5A the useable capacity was still quite decent. In overall the 1.5V AAA Varta Superlife batteries seem to be one of the best performing among all AAA size Carbon Zinc models we’ve tested so far. Note that if you opt out to use carbon Zinc batteries you should have in mind that they are offering less capacity than Alkaline and are not a good choice for applications where higher current is required.

The performance of the 1.5V AAA Varta Superlife Carbon Zinc batteries in our tests:

– 372 mAh at 0.1A load
– 240 mAh at 0.2A load
– 192 mAh at 0.3A load
– 113 mAh at 0.5A load

– 0.441 Wh at 0.1A load
– 0.272 Wh at 0.2A load
– 0.211 Wh at 0.3A load
– 0.110 Wh at 0.5A load
