1.5V AAA Sony Stamina Plus Alkaline Battery Tests

The 1.5V AAA Sony Stamina Plus Alkaline batteries are supposedly better than the standard Sony Alkaline batteries and not as good as the Stamina Platinum series, so they should be mid-range Alkaline batteries. The expiration date on the batteries we have used for testing was 08-2018, meaning they should be offering 5 years shelf life which is not a bad thing to have if you plan to use them in low drain applications. It is more important however to see what capacity they will be able to provide in our test to see if they are a good choice or you might be able to get better Alkaline batteries then them at a better price for example.

Starting our test of the 1.5V AAA Sony Stamina Plus Alkaline batteries as usual with a low constant current discharge rate of 0.1A we have managed to get just 772 mAh as capacity , a result that we consider a bit disappointing, especially considering this is not the “lowest-end” Alkaline batteries from Sony. Testing with higher loads the batteries do manage to perform quite well compared to others we’ve tested, bt again not that good capacity as we’ve expected to see from Sony.

The performance of the 1.5V AAA Sony Stamina Plus Alkaline batteries in our tests:

– 772 mAh at 0.1A load
– 529 mAh at 0.2A load
– 365 mAh at 0.3A load
– 251 mAh at 0.5A load

– 0.957 Wh at 0.1A load
– 0.640 Wh at 0.2A load
– 0.441 Wh at 0.3A load
– 0.292 Wh at 0.5A load

1.5V AAA Sony New Ultra Carbon Zinc Battery Tests

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
