6 Battery Charging Guide
English
■
Before you begin to charge your battery, make
sure that the battery temperature is close to the
room temperature in which the battery is to be
charged.
■
If possible, charge the battery in temperatures
between 50 °F and 77 °F (between 10 °C and 25 °C).
This temperature range is the optimal charging range.
Charging only starts when the battery is between the following
temperature ranges:
■
Li-ion battery: 32 °F to 104 °F (0 °C to 40 °C)
■
NiMH battery: 32 °F to 113 °F (0 °C to 45 °C)
Although charging of NiMH batteries will only start if the battery
temperature is below 113 °F (45 °C), charging will
continue up to
131 °F (55 °C).
Temperature indications
When the battery temperature is outside the normal charging range,
the orange LED on the charger is lit. Charging will start or resume
once the temperature is within normal limits, and no action is
required by you.
Leaving the battery on charge
You can leave a battery/radio in the charger once charging is
complete. Leaving a battery in the charger will not overcharge or
damage it.
You can remove a battery/radio from the charger at any time
without harming the battery, the radio, or the charger. When you
return the battery/radio to the charger, charging is automatically
resumed.
Vehicle charger only
It is safe to switch off the ignition while there is still a battery in the
charger. But if the vehicle will not be used again for some time, check
whether charging will continue while the ignition is off, and consider
what effect this might have on the vehicle battery.
To check, place the battery in the charger and switch off the vehicle
ignition:
77 °F
25 °C
50 °F
10 °C
