1-5v-aa-maxell-alkaline-battery

The 1.5V AA Maxell Alkaline batteries are the mid-range Alkaline batteries from Maxell, they also have a Super Alkaline series that is supposed to offer a bit more capacity than this standard Alkaline models and we’ll test them s well to confirm. The 1.5V AA Maxell Alkaline batteries we got for testing here are with an expiration date of 01-2018, so they are offering quite a long shelf life, but let us see what they will offer in terms of capacity and how good they will perform compared to other Alkaline batteries we’ve tested so far…


1-5v-aa-maxell-alkaline-battery-capacity

Beginning our test of the 1.5V AA Maxell Alkaline batteries with a constant current discharge rate of 0.1A we’ve managed to get 2237 mAh capacity and that is a very good result though not the highest we’ve got from Alkaline batteries we’ve tested already. Increasing the constant current load further and these Alkaline batteries from Maxell still manage to perform quite well, so we can say that they are providing above the average capacity and this only rises our expectation from Maxell’s Super Alkaline batteries that are supposed to offer even better results.

The performance of the 1.5V AA Maxell Alkaline Batteries in our tests:

– 2237 mAh at 0.1A load
– 1807 mAh at 0.2A load
– 1010 mAh at 0.5A load
– 483 mAh at 1.0A load

– 2.775 Wh at 0.1A load
– 2.166 Wh at 0.2A load
– 1.164 Wh at 0.5A load
– 0.538 Wh at 1.0A load

1-5v-aa-panasonic-pro-power-alkaline-battery

The 1.5V AA Panasonic Pro Power Alkaline batteries are from the mid to high-range of primary batteries from Panasonic situated at one level below the top Evolta range of Alkaline batteries. Panasonic claims that it has improved capacity of the new Pro Power batteries so that they can offer up to 80% extra performance compared to their last years Alkaline range of batteries (the maximum difference measured between Panasonic Pro Power production 2012 and Panasonic Standard Power production 2011 by Panasonic). The 1.5V AA Panasonic Pro Power Alkaline batteries we got for testing are with an expiration date of 02-2020, so quite a long shelf life for these batteries. Panasonic says that these are ideal for high and medium drain appliances, so let us see how they perform in our tests.

Starting our tests of the 1.5V AA Panasonic Pro Power Alkaline batteries as usual with a constant current discharge rate of 0.1A we’ve managed to get 2517 mAh capacity and that is actually a very good result fr an Alkaline battery, though not the highest we’ve got so far (we should also check the Panasonic Evolta batteries). Increasing the constant current discharge rate to 0.2A and the batteries still manage to handle very well, and even going further we are still getting very good performance. So the 1.5V AA Panasonic Pro Power Alkaline batteries are probably among the top Alkaline batteries you can currently get, and they are certainly giving better results than the standard Duracell Copper Top batteries.

The performance of the 1.5V AA Panasonic Pro Power Alkaline Batteries in our tests:

– 2517 mAh at 0.1A load
– 1859 mAh at 0.2A load
– 1178 mAh at 0.5A load
– 572 mAh at 1.0A load

– 3.159 Wh at 0.1A load
– 2.298 Wh at 0.2A load
– 1.378 Wh at 0.5A load
– 0.636 Wh at 1.0A load

1-5v-aa-toshiba-super-heavy-duty-carbon-zinc-battery

The 1.5V AA Toshiba Super Heavy Duty batteries are of the Carbon Zinc type, however this is not mentioned anywhere on the battery itself and this along with the fact that the batteries are labeled as Super Heavy Duty gives out the fact that they are indeed Carbon Zinc. This simply means that the 1.5V AA Toshiba Super Heavy Duty batteries that we test here with an expiration date of 04-2016 are not going to provide as much capacity as an Alkaline battery. We are not very happy when we find a Carbon Zinc battery that is not clearly labeled as such as that may be misleading the buyer, especially if not careful enough. As a general rule of thumb Alkaline batteries should have Alkaline written on them as opposed to Carbon Zinc batteries do not have that clearly stated.

Anyway, lets us see what we can expect in terms of performance from these Carbon Zinc batteries from Toshiba. Starting our tests of the 1.5V AA Toshiba Super Heavy Duty batteries with a constant current discharge rate of 0.1A we’ve managed to get 874 mAh capacity and that is actually not bad for a Carbon Zinc battery. Doubling the constant current discharge rate to 0.2A and the batteries still manage to handle pretty well, however by further increasing the load to the 1.5V AA Toshiba Super Heavy Duty Carbon Zinc batteries they are starting to offer significantly less capacity. This is to be expected as Carbon Zinc batteries are intended for use in cases where low power is required.

The performance of the 1.5V AA Toshiba Super Heavy Duty Batteries in our tests:

– 874 mAh at 0.1A load
– 661 mAh at 0.2A load
– 298 mAh at 0.5A load
– 45 mAh at 1.0A load

– 1.065 Wh at 0.1A load
– 0.773 Wh at 0.2A load
– 0.317 Wh at 0.5A load
– 0.046 Wh at 1.0A load
