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

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

Since we’ve just tested the Panasonic Eneloop Pro AAA NiMH batteries and there are some claims that the IKEA LADDA AAA NiMH batteries that we have also tested recently are the same as the Eneloop (both are low self discharge and made in Japan with similar capacity) we could not pass the chance to compare them. IKEA’s LADDA brand is available at significantly lower prices compared to the top of the line Eneloop Pro batteries and even though IKEA does not make any bold claims about their batteries like Panasonic, the LADDA batteries could easily end up as a great and more affordable alternative…

Looking at the test results with discharge of both battery types with the same settings under different constant current loads we can see very similar performance and results, though there are some slight differences we can conclude that it is very highly likely that they are being made in the same place. The IKEA LADDA batteries managed to give us a bit higher capacity at lower discharge rates (0.1A and 0.2A), but fell behind a bit at higher loads (0.5A and 1.0A). Looking at the discharge curves we see a very similar pattern for both the Eneloop Pro and the IKEA LADDA batteries and that along with the results makes us think that they are essentially the same thing, but produced for different companies and sold under different brands. Of course there could be more variance in the LADDA batteries if they are allowed a wider tolerance in production for example as they are rated at 900 mAh and since IKEA sells a lot without much of marketing going for a specific products like their batteries it could apparently manage a better price for what seems to be the same thing.
