Maintenance instruction for EX-battery SR 501 EX
(Art. No. R06-2002)
For the longest battery lifetime SR 501 EX should have regular charging and discharging
cycles. Best results are achieved with full discharge directly followed with a full charge.
Charge the battery in accordance with paragraph 2, below.
When the battery is not used for a long time, the following should be considered:
The battery contains a protection circuit that consume power from the battery.
This allows the battery to be deeply discharged if stored for a long time, which can cause
damage to cells.
Prolonged maintenance charge is also not recommended as this can also be harmful to the
cells. Instead, we recommend a scheduled charge under paragraph 3.
