Charging temperatures
Notice Do not expose a battery to very high or very low
temperatures for extended periods of time. Doing so will
shorten the usable life (‘service life’) of the battery.
To achieve the best results when charging your battery:
■
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
32 °F to 104 °F (0 °C to 40 °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. However, if the vehicle will not be
used again for some time, check whether charging will
