When we buy (rechargeable) batteries, it's mostly with the intention to use them as long as possible. Battery care en battery storage is therefore essential to extend the lifetime of the batteries. But where do you need to store your (rechargeable) batteries when you're not using them?
When storing your batteries, keep in mind the temperature can't be extreme. The recommendation says batteries need to be stored around 15°C. Keep your batteries away from the sun and choose any cool and dry room for the storage. A battery loses charge capacity when temperatures are extreme. Keep in mind that batteries self-discharge when they're in storage. But eneloop rechargeable batteries keep 70% of their capacity even after 10 years of storage.
