Charge the Battery
The standard WSM6 is fitted with Nickel Metal Hydride rechargeable battery. The Type 7972-000-
04 Charger will charge the batteries in approximately 4 hours.
The WSM6 includes special circuitry to monitor the battery pack during charging. This safety
feature makes sure the battery cannot be over-charged in normal use.
The WSM6 should always be switched off when not in use to minimise entering into a deep
discharge state. In this state it is possible for some cells to drop to near zero voltage or even
reverse the voltage of their terminals.
There are four states of charge for the battery, each requiring different charging methods.
For a battery that is partially discharged proceed with the charging instructions in this section. For
any other charge condition of the battery refer to
Section 6.3 - WSM6 Battery Charging
.
To charge the battery:
