Picked up a pack of fresh 1.5V AAA Sony Alkaline Blue (AM4L-B4D) batteries to test and see how well will they perform. The batteries are produced in 01-2019 and Sony claims that these are longer lasting batteries that can keep power for up to 8 years (expiration date 01-2027) if properly stored at ambient temperature between 18 and 22 degrees Celsius. Of course most people do not care much for their batteries and will probably not try to extend their live, especially for cheaper alkaline batteries like these, so hardly they will be kept under optimal conditions. With alkaline batteries you usually pick a pack and put them right to some use in a device, so just make sure you get a freshly produced cells.
The 1.5V AAA Sony Alkaline Blue batteries do manage to show good results in our tests with capacity above average (closer to the top performers in the AAA alkaline category) and better than what we have got a couple of years ago from Sony Stamina Plus AAA batteries. We are getting high usable capacities for 0.1A, 0.2A and 0.3A constant current loads and going for the higher 0.5A discharge test we see a more significant drop in the usable capacity. The longer 8 year shelf life of the batteries is also a plus, compared to the regular 5 years that most alkaline batteries normally get.
The performance of the 1.5V AAA Sony Alkaline Blue batteries in our tests:
– 910 mAh at 0.1A load
– 784 mAh at 0.2A load
– 609 mAh at 0.3A load
– 324 mAh at 0.5A load
– 1.101 Wh at 0.1A load
– 0.926 Wh at 0.2A load
– 0.692 Wh at 0.3A load
– 0.362 Wh at 0.5A load
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
