Why You Should Not Charge Your Lithium-Ion Battery Before Storing It

Today, battery technology uses lithium-ion as standard, and these cells experience negligible levels of self-discharge. To protect cells from over-discharge a lithium-ion battery is usually built with separate integrated fuses that can automatically switch a highly discharged battery to a rest state so they don't need to be fully charged before storage. In fact, lithium-ion battery life is extended if it goes into storage partly charged – that said, it's worth remembering that cells are negatively impacted in the event of storage with a very low level of charge or if the battery is fully charged. We recommend that you store a lithium-ion battery with two lit LEDs, indicating a charge of 40-60%, to minimise ageing and self-discharge.
