The 1.5V AA Toshiba Alkaline batteries are a standard Alkaline batteries with no fancy naming to tell you they are something special or different than normal primary batteries for single use. In fact these are the Standard Alkaline batteries from Toshiba, though they also have a lower-end Blue Line Alkaline batteries and higher-end named Alpha Power. The shelf life of the 1.5V AA Toshiba Standard Alkaline batteries is supposed to be 7 years and the expiration date of the ones we used for the tests here is 06-2019. According to Toshiba these batteries are ideal for portable radios, handheld computers, pagers, pocket electronic games etc. Surprising we even found something like a specs sheet for these batteries on Toshiba’s website, though it did not mention anything about expected capacity, you can find the link below.

We have started the test of the 1.5V AA Toshiba Alkaline batteries with a constant current discharge rate of 0.1A here we’ve managed to get 2467 mAh and that is nothing short of great performance at this level of constant current load. Furthermore going at 0.2A the batteries also performed superb, though at even higher constant current load levels their performance is a bit lower than the best performing models we’ve tested so far. So it seems that these Toshiba Standard Alkaline batteries are great for use in devices with lower power requirements, where they can provide the best performance they can. At lower constant current load these batteries were able to outperform the standard Duracell Copper Top Alkaline batteries, though at higher loads the Duracell performs slightly better.

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

– 2467 mAh at 0.1A load
– 1903 mAh at 0.2A load
– 1025 mAh at 0.5A load
– 324 mAh at 1.0A load

– 3.067 Wh at 0.1A load
– 2.286 Wh at 0.2A load
– 1.189 Wh at 0.5A load
– 0.352 Wh at 1.0A load

1.5V AA Toshiba Super Heavy Duty Carbon Zinc Battery Tests

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
