1.5V AAA Sony Stamina Plus Alkaline Battery Tests
16, Sep 2013
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 Xcell Alkaline Battery Tests
14, Sep 2013
The 1.5V AAA Xcell Alkaline batteries are nothing special at first look and are not a popular or well known brand, so we took them for a spin to see how good they will perform in our tests, The particular batteries we are testing here were all marked with an expiration of 2017, no particular month mentioned so we can assume they have a shelf life of 4 years.
Starting our test of the 1.5V AAA Xcell Alkaline batteries as usual with a low constant current discharge rate of 0.1A we have managed to get 893 mAh as capacity – a decent achievement, though a bit far from the highest result we’ve seen. Increasing the load to 0.2A, 0.3A and even at 0.5A the useable capacity we’ve got was still very decent. The interesting thing here is that the difference between the shown useable capacity at the higher test loads was with smaller gaps, indicating that these batteries are designed to handle well higher current loads. The Xcell Alkaline batteries seem to perform well, but are nothing special in terms of performance…
The performance of the 1.5V AAA Xcell Alkaline batteries in our tests:
– 893 mAh at 0.1A load
– 532 mAh at 0.2A load
– 400 mAh at 0.3A load
– 314 mAh at 0.5A load
– 1.072 Wh at 0.1A load
– 0.600 Wh at 0.2A load
– 0.450 Wh at 0.3A load
– 0.351 Wh at 0.5A load
1.5V AAA Maxell Super Alkaline Battery Tests
12, Sep 2013
The 1.5V AAA Maxell Super Alkaline batteries are supposedly better than standard Alkaline batteries that Maxell makes and are intended for high-drain devices according to the company. The batteries we’ve had for testing were with an expiration date of 01-2017 meaning that the shelf life is at least 4 years, though we are not exactly sure when these batteries were produced so it might also be 5 years. Anyway, let us see how good these 1.5V AAA size Alkaline batteries from Maxell perform in terms of useable capacity in our tests…
Starting our test of the 1.5V AAA Maxell Super Alkaline batteries as usual with a low constant current discharge rate of 0.1A we have managed to get 948 mAh as capacity and that is actually a very good result. Increasing the load to 0.2A and 0.3A the Maxell batteries do manage well, and even at 0.5A the useable capacity was still quite decent. In overall these Alkaline batteries seem to be doing quite well, but do not provide as much capacity as an Alkaline Duracell battery of the same type for example does (we use Duracell as a reference), so there is more to be desired.
The performance of the 1.5V AAA Maxell Super Alkaline batteries in our tests:
– 948 mAh at 0.1A load
– 572 mAh at 0.2A load
– 474 mAh at 0.3A load
– 253 mAh at 0.5A load
– 1.135 Wh at 0.1A load
– 0.675 Wh at 0.2A load
– 0.552 Wh at 0.3A load
– 0.282 Wh at 0.5A load
