the battery is fully charged you will see the
temperature rise and
the charger will switch-off when the rise equals
5<198>Celsius.
One CHARGE is enough. It is possible to raise
the battery temperature
by charging three or four times in succession,
which raises temperature
by 5 degrees each time. This does not put any
extra charge in the
battery or achieve anything useful.
To terminate INFO mode, press ESCape.
Automatic Battery Charging
When S4 is turned on, it charges the battery if the
"FUEL GAUGE" shows
less than 75% full. The charger will replenish the
battery in less
than an hour. There is a temperature sensor in
contact with the battery.
When it sees a 5<198>C rise, the charge current
turns off. Charging
is thus perfectly safe and S4 may be used normally
whilst being charged.
The internal circuitry prevents the batteries
overcharging. While
capacity remains they are capable of absorbing
high currents, but
when fully charged the current is not stored - it is
dissipated
as heat. S4 monitors battery temperature, looking
for a 5<198>C rise
at which point the high current is turned off. S4
remains on when
charging - but will turn itself off automatically
when the job is
