STORAGE
Pagbelts can be stored indefinitely in any state of charge (even totally dis-
charged) without significant loss of cell life. Maintenance charging is not
required. Store in a cool, dry place. Ideally the temperature should be from -
20°C to +30°C. High storage temperatures (above +45°C) will reduce the
battery’s life because of unwanted chemical reactions. Excessively low
storage temperatures (below -30°C) are also to be avoided since the
electrolyte may freeze result-ing in permanent cell damage.
After prolonged storage do not fast-charge the battery immediately. The cells
should first be reformed and balanced by giving the battery a slow (C/10)
charge for 24 hours. When the battery is subsequently put into service, 2 or 3
cycles of charge and discharge may be needed to return the battery fully to its
rated capacity.
The battery belt should be in a fully charged state before use. Even after one
week in storage the battery should be given a top up charge before use.
At room temperature (20°C) Nickel-Cadmium batteries lose 1% of their charge
per day. The top-up charge needed is one hour at C/10 for each week of
storage.
2.2
Charge the battery belt only from constant current chargers - see Section 3,
Instructions For Use. Constant voltage chargers must not be used.
2.3
For maximum output, use within the temperature range 0°C to +40°C.
Never operate outside of the temperature range -20°C to +45°C.
