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

The 1.5V AA Varta High Energy Alkaline batteries are a slightly improved version of the Varta Simply Alkaline batteries and according the the manufacturer these should be able to provide 23% more power than the normal Varta Alkaline batteries. The batteries we have tested here have an expiration date of 06-2016, so they should be with a 5 year shelf life as they appear to have been produced in 07-2011. Varta does not provide detailed specifications about these batteries, but the company recommend their use for power-hungry devices, e.g. computer devices, audio equipments, toys etc. So lets us see how good these batteries perform in our tests.

Starting the tests of the 1.5V AA Varta High Energy Alkaline batteries with a constant current discharge rate of 0.1A we were very pleasantly surprised by the result we got – 2700 mAh capacity or with other words one of the best performing 1.5V AA-size Alkaline batteries we’ve tested so far with low current constant load. Moving to higher constant current loads these Varta batteries still perform great outperforming for example the standard Duracell Copper Top batteries by a bit and these are not the “toughest” Alkaline batteries from Varta. Compared to the Duracell Procell batteries however the 1.5V AA Varta High Energy Alkaline batteries only manage to provide slightly more capacity at 0.1A constant current load, but at higher loads the Procell performs better. Anyway, we are seeing a really great performance from these Varta batteries.

The performance of the 1.5V AA Varta High Energy Alkaline Batteries in our tests:

– 2700 mAh at 0.1A load
– 1941 mAh at 0.2A load
– 1216 mAh at 0.5A load
– 537 mAh at 1.0A load

– 3.332 Wh at 0.1A load
– 2.327 Wh at 0.2A load
– 1.371 Wh at 0.5A load
– 0.589 Wh at 1.0A load

9v-gp-ultra-alkaline-battery

The 9V GP Ultra Alkaline batteries we test here are rated with up to 5 years shelf life and are marked for use up to 01-2018. The GP Batteries website does not have detailed specifications about these batteries, so we have to check them out by testing the actual capacity we can get out of these.


9v-gp-ultra-alkaline-battery-capacity

To test the capacity that 9V alkaline batteries can provide we are using a constant current discharge test with 0.05A load (50 miliampers) due to the fact that the total capacity of these batteries is not that high and they are not intended for use in situations where high current loads can be expected. The 9V GP Ultra Alkaline battery we have tested here managed to provide 319 mAh capacity before hitting the 6.6V cutoff voltage and that is a bit less than what we have expected from that 9V alkaline battery.

The performance of the 9V GP Ultra Alkaline Batteries in our tests:

– 319 mAh at 0.05A load

– 2.373 Wh at 0.05A load
