Maintaining battery life and
performance
With proper care and maintenance you will maintain
the performance and life of the battery. It is
recommended that you:
Q
Use only Tait chargers.
Q
Avoid exposing batteries to high temperatures
(above 122°F (50°C)) or extremely cold
temperatures for long periods of time (-4°F
(-20°C) for NiMH, and -22°F (-30°C) for NiCd).
Q
Charge batteries at room temperature (between
50°F (10°C) and 77°F (25°C)).
Q
Allow your nickel-based battery to fully discharge
every so often—NiCd batteries once a month and
NiMH batteries once every 3 months. To do this,
leave your radio switched on and ignore the
‘battery low’ warnings. When the radio switches
off, the battery is fully discharged.
Q
Store batteries properly when not in use. See
“Storing batteries” on page 57.
