See section 9.9.3, LEMO CONNECTOR, for details of connecting and
removing the LEMO plug.
HUNTER operation is possible during use of the charger but the
current drain will counteract the charging current and
consequently prolong the time to fully charge the batteries.
Removal of the cells under this condition is forbidden.
As with all electrical apparatus the charger should be dis-
connected from the mains when not in use. Only 240 vAC (220 to
250v) mains, 50 or 60 Hz is suitable for standard units.
Chargers for alternative mains supplies, e.g. 110v, are
available,
Exhausted batteries will typically be fully charged in 12 hours,
overnight charging is a popular practice.
NICAD REPLACEMENT
It must not be forgotten that rechargable batteries do not have
an unlimited life and will ultimately need replacing as do car
batteries.
If the batteries become exhausted after little use
then the set may need replacing. Their life expectancy can be
several years but this is reduced by repeated or prolonged total
discharge and by excessively high temperatures.
NOTE: Several discharge/charge cycles are required before NiCad
cells reach their peak capacity. This type of battery will also
self discharge, especially at elevated temperatures, which can
result in a fully charged set of batteries becoming flat in a
few weeks. An occasional charging session, say, every fortnight
is recommended if HUNTER is being stored.
HAINS OPERATION
For critical or remote operations, permanent charging may be
called for. This is acceptable provided ventilation around the
charger and HUNTER is good, but ageing of the cells may be
accelerated, Annual replacement would be a prudent action in
this instance.
