For disposable 6V batteries, proper storage primarily involves keeping them in their original packaging until ready for use, as this protects them from moisture and short circuits. Store them in a cool, dry environment, as high temperatures can accelerate their self-discharge rate and reduce their shelf life. Never store batteries loose in a drawer or pocket where they can come into contact with metal objects, which can cause a short circuit, leading to heat generation and potential leakage or fire hazards. If a disposable battery shows any signs of leakage or corrosion, it should be handled with care and disposed of properly according to local regulations to avoid damage to the device or personal injury.
