Note:
Damage caused by the battery being left uncharged for a long period is irreversible and is
not covered by the limited warranty. Once the damage has occurred, the battery cannot
be recharged (the battery must not be disassembled by unqualified personnel, as this
could lead to electric shocks, short circuits or even major safety incidents).
