Battery Maintance: Batteries should be discharged before each charging. And it’s best to make the battery fully charged without interrupting If you store a battery when it's fully discharged, it could fall into a deep discharge state, which renders it incapable of holding any charge NiCd, NiMh and Lithium ion batteries will self-discharge during storage; We recommend using the battery at least once every two to three weeks
