    what’s the best way to keep this battery charged or uncharged?
    Asked by: david
    The Celestron PowerTank Lithium should be kept at around 40-50% State of Charge to be ready for immediate use – this is approximately 3.8 Volts per cell – while tests have suggested that if this battery type is kept fully charged the recoverable capacity is reduced over time. The voltage of each cell should not fall below 2 volts as at this point the anode starts dissolving causing copper shunts to form which will cause an irreversible loss of capacity. Similarly lithium based batteries can be damaged by over charging which causes the cathode to decompose.
