A great move for the environment! I’m using rechargeable batteries in everything I can now. Although one or two devices (like my weather station) report the batteries are flat, they work fine. The issue is rechargeables are generally 1.2V fully charged and keep that voltage before dropping off when empty, whilst disposables start at 1.5V fully charged and slowly drop voltage during their use.
See Ikea is saying goodbye to non-rechargeable batteries
The company will remove all non-rechargeable alkaline batteries from its global home furnishings by October 2021.
