Battery Charging - AVO MEGGER BM25 Guide De L'utilisateur

General
It is advisable to fully charge the battery before the instrument is
put into service for the first time. Charging is carried out by
external a.c. mains supply, or by 12 V d.c. supply. A 12 V
charging lead fitted with an automotive cigar lighter plug is
available for charging the battery from a vehicle.Testing is
inhibited during charging.
Mains supply re-charging
Mains input recharging requires a voltage within the range 95 -
265 V a.c., 50 - 60 Hz. Disconnect the test leads and
connect the mains supply to the IEC 320 connector in the
charging recess. Confirm that the red indicator lamp is
illuminated. Charging is automatic as soon as the mains supply
is connected. To fully recharge the battery takes about 16 hours.
Eight hours charging (from a fully discharged state) will achieve
at least 90% of full charge. Turn the instrument on and check the
battery capacity indicator to show the state of charge.
12 V d.c. supply re-charging
This method of re-charging should only be carried out if a mains
supply is unavailable as it is slower and less efficient. If using a
vehicle as the charging source, the engine should be running.
Observing correct polarities shown, connect the 12 V
socket to the external 12 V d.c. supply and switch on.
Caution: Applying more than 15 V to this socket will overcharge
the battery.

Battery Charging Notes
1) Do not leave battery in a totally discharged state. Frequent
2) Battery charging should be carried out in a dry environment
3) When charging the battery indoors, the area should be well
4) The battery should only be charged at temperatures in the
5) It is beneficial to continue charging and no harm will occur
6) If the instrument is idle for long periods, recharge the battery
