All batteries need to be stored upright and in cool and dry conditions to maximise self life. They have a limited shelf life and when stored self-discharge and lose their power to perform. On average, a fully-charged battery takes about 13 weeks to self - discharge to less than its optimum operating level. The rate of self - discharge depends on: Type of battery (calcium and AGM have lower self discharge than conventional batteries) Temperature conditions (batteries discharge quicker in higher temperatures). Charge loss becomes more evident when temperatures increase.. At 20C – 30C maintenance free batteries lose their charge more slowly than low maintenance batteries. Excessive humidity will also accelerate charge loss. Whilst in storage batteries that have not been recharged and go flat, may become permanently damaged. It is recommended to recharge every 4 -8 weeks, depending on storage conditions, will restore batteries to "as new" condition.
