The 1.5V AAA Sony New Ultra batteries are of the Carbon Zinc type even though that is not marked on the batteries themselves. The batteries we got for testing here were with an expiration date of 11-2015, so they are supposedly offering a shelf life of 3 years. And what about their capacity you’d probably ask, well as is the case with Carbon Zinc batteries you should not expect much, but let us see what capacity these Sony New Ultra batteries will show in our tests.

We have started the test of the 1.5V AAA Sony New Ultra Carbon Zinc batteries as usual with a low constant current discharge rate of 0.1A and the result we got was 341 mAh as capacity which is a value expected from a decent Carbon Zinc battery. Increasing the load to 0.2A and 0.3A the Sony batteries still did pretty good and at 0.5A the useable capacity was let us say not that good. 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 Sony New Ultra Carbon Zinc batteries in our tests:

– 341 mAh at 0.1A load
– 212 mAh at 0.2A load
– 155 mAh at 0.3A load
– 83 mAh at 0.5A load

– 0.402 Wh at 0.1A load
– 0.239 Wh at 0.2A load
– 0.168 Wh at 0.3A load
– 0.084 Wh at 0.5A load

Thank you for sharing with us the capacity of this battery. I’ve tested one and the capacity was around 350mAh @ 100mA which is the same you’ve got. 🙂
