Tests and reviews of different batteries to help you find the Right One…
The 1.5V AAA Toshiba Super Heavy Duty batteries despite their good sounding names are essentially Carbon Zinc batteries, though that is not marked anywhere on the batteries themselves and these are commonly found in supermarkets for example. The batteries we got for testing were with an expiration date of 04-2016, so they are supposedly offering a shelf life of 3 years, but what about their capacity. As is the case with Carbon Zinc batteries you should not expect very high capacity, but let us see what these Toshiba Super Heavy Duty batteries can offer in terms of capacity in our tests.
We have started the test of the 1.5V AAA Toshiba Super Heavy Duty Carbon Zinc batteries as we normally do with a low constant current discharge rate of 0.1A and the result we got was 320 mAh as capacity, not that much as we expected from a Carbon Zinc battery. By further increasing the constant current load to the higher values we test with and the batteries started providing even less useable capacity, something that is to be expected, but while Carbon Zinc batteres do provide less capacity than their Alkaline counterparts they are also not a good choice for applications requiting more power. Nevertheless we got a decent result for a Carbon Zinc batteries from the 1.5V AAA Toshiba Super Heavy Duty Carbon Zinc batteries.
The performance of the 1.5V AAA Toshiba Super Heavy Duty Carbon Zinc Batteries in our tests:
– 320 mAh at 0.1A load
– 195 mAh at 0.2A load
– 138 mAh at 0.3A load
– 58 mAh at 0.5A load
– 0.379 Wh at 0.1A load
– 0.219 Wh at 0.2A load
– 0.147 Wh at 0.3A load
– 0.060 Wh at 0.5A load
