Charging the battery before
first use
Before using your battery for the first time, you must
charge it for 14 hours (subsequent charges should be
complete in two hours or less). This first charge is
important because it prepares (‘primes’) the battery for
use. The battery may take two or three shifts (charge/
discharge cycles) to reach maximum capacity.
Note: Before charging begins, the battery temperature
must be close to the room temperature in which the
battery is to be charged. Charging is best performed at
temperatures between 50 °F (10 °C) and 77 °F (25 °C)
and will start only when the temperature of the battery
is between 41°F (5°C) and 95°F (35°C).
1 Ensure that the charger is connected to the correct
Tait power adaptor (desktop charger) or powered on
(multi-charger).
2 Put the battery in the charger.
Note: For optimal charging
results, the radio should be
turned off while in the charger.
The red ‘Charging’ LED glows to
indicate that the battery is being charged.
Note: If the amber ‘Fault’ LED lights up, refer to
“General care” on page 97 .)
3 Leave the battery in the charger for 14 hours . When
the green ‘Ready’ LED on the charger glows, the
battery is ready for use.
You can safely leave the battery in the charger when
charging is complete—the charger will not overcharge
the battery.

caring for batteries” on page 77 .
