Charging Battery Packs; Warning - MSA Omega Five Unit Supply Mode D'emploi

Charging Battery Packs

Nickel-cadmium battery packs can be recharged while either connected
to their instruments or separately. If the battery pack is connected to its
instrument, the instrument must be turned OFF to allow the pack to
charge properly.
Only Omega-compatible battery packs can be recharged using the
Omega Five Unit Charger.
Connect the charger OUTPUT plug to the battery pack CHARGER jack.
Most battery packs will completely recharge within 16 hours. The pack
may be disconnected after that time. No damage will result to the
battery if it remains connected to the proper battery charger.
RISK OF EXPLOSION OR FIRE: Operate only in a non-haz-
ardous location known to be free of combustible gases and
vapors.
Nickel-cadmium batteries exhibit, to varying degrees, a behavior known
as "memory." When they are used repeatedly in a shallow-discharge
application, they gradually appear to lose capacity and do not perform
well in full-discharge use.
For example, if an instrument having an initial eight-hour battery
capacity is repeatedly used for one hour at a time and recharged after
each use, the battery may not operate for the expected eight hours
when eight hours of operation is demanded. Batteries used in MSA
battery packs are designed to minimize this "memory" effect. However,
it may not be completely eliminated. The "memory" effect is a temporary
condition that is remedied by discharging the battery pack until the
instrument battery alarm flag or LO BATT is activated. Then, recharge
the pack following the procedures outlined in the instruction manual.
