Energy storage batteries, particularly lithium-ion types, should not be left idle for extended periods without maintenance.They can lose about 0.5% to 3% of their charge monthly while idle1.It is recommended to check the battery every three months to ensure it does not drop below 20% charge, and recharge it to 40% to 60% if necessary2.For optimal shelf life, store lithium-ion batteries at a charge level between 40% and 60%3.Regular checks and maintaining the appropriate charge level can help prolong the battery's lifespan while idle.
