1.5V AAA Sony Alkaline Blue Battery Tests

13, Mar 2019

We have 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 AA IKEA Alkalisk Alkaline Battery Tests

11, Mar 2019

Time for another tests of 1.5V IKEA Alkalisk alkaline batteries, this time a pack of AA sized batteries with a fresh production date that we especially check when picking up the 10-battery pack from the store (after getting AAA IKEA alkaline batteries with old production date recently). The production date of these affordably priced batteries from IKEA is 07-12-2018 and the expiration date is 2023, so a 5 year warranty and pretty fresh batch of batteries at a good price in 10-pack box, but let us see what we can expect from them in terms of usable capacity in our tests…


The 1.5V AA IKEA Alkalisk Alkaline batteries are performing quite well in our tests all the way up to the 0.5A constant current load, after which the usable capacity shows a larger drop. The capacity levels are above average for these IEKA batteries, but are far from the top performers in our tests. Still the 1.5V AA IKEA Alkalisk alkaline batteries do manage to provide a very good price/performance ratio for everyday use without having some more specific requirements.

The performance of the 1.5V AA IKEA Alkalisk Alkaline batteries in our tests:

– 2127 mAh at 0.1A load
– 1845 mAh at 0.2A load
– 974 mAh at 0.5A load
– 310 mAh at 1.0A load

– 2.618 Wh at 0.1A load
– 2.230 Wh at 0.2A load
– 1.108 Wh at 0.5A load
– 0.344 Wh at 1.0A load

1.5V AAA IKEA Alkalisk Alkaline Battery Tests

10, Mar 2019

We have picked up a pack of 1.5V AAA alkaline batteries from an IKEA store to give a quick test of these very affordably priced pack of 10 AAA batteries. Normally we end up with pretty fresh stock of batteries when we buy from an IKEA store, especially when we are talking about single-use alkaline batteries, so we do not pay that much attention to the production date. Of course when doing a test of alkaline batteries production and expiration dates are important, so we were kind of surprised to see that the pack we got was with a 08-07-2016 production date and with 5 years warranty up until 2021. This of course would mean a slightly reduced performance of these batteries in our capacity test and it also leads us to another important tip – always check the production and expiration dates when you purchase alkaline batteries and go for fresher ones if possible!


The 1.5V AAA IKEA Alkalisk Alkaline batteries, even though a bit older as production dates still manage to deliver a pretty good performance in our tests, although they are nowhere near the top performers. At 812 mAh usable capacity with 0.1A constant current load the result is above average and that is good for an affordably priced pack of alkaline batteries, especially ones that are at the half of their product life even when not used. With increased discharge loads however the results re not that good, at 0.2A with 577 mAh still quite Ok, but at 0.3A and 0.5A he usable capacity we get is a bit on the lower side.

The performance of the 1.5V AAA IKEA Alkalisk Alkaline batteries in our tests:

– 812 mAh at 0.1A load
– 577 mAh at 0.2A load
– 378 mAh at 0.3A load
– 162 mAh at 0.5A load

– 0.964 Wh at 0.1A load
– 0.650 Wh at 0.2A load
– 0.418 Wh at 0.3A load
– 0.174 Wh at 0.5A load
