The 9V Alkalisk alkaline battery is a fresh from the IKEA store standard alkaline battery produced in mid-November 2018 with expiry date in 5 years up to the end of 2023, so we expect to see good results from this battery. With alkaline batteries the closer to their production date they are the better capacity you can get out of them and with IKEA batteries selling out fast you can expect to get fresh ones with your visit to the store. You should still of course check the production and expiry date printed on the packaging and on the battery itself just to be sure though.

Our tests of 9V alkaline batteries are at a constant current discharge rate of 0.05A (50 milliamps) and we have managed to get surprisingly good result with 492 mAh for the 9V IKEA Alkalisk Alkaline Battery. This is the best result so far for 9V alkaline batteries we have tested so far in terms of usable capacity at our specific test conditions, so good job to IKEA with this one.

The performance of the 9V IKEA Alkalisk Alkaline batteries in our tests:

– 492 mAh at 0.05A load
