Starting characteristics
The battery is designed for high load (brief high
current). The battery´s ability to supply power is
reduced when very cold. The capacity is specified
for 25°C (77°F) and it falls by about 0.8% per °C
(2°F). The capacity does not disappear altogether
when cold. The battery regains full power when it
becomes warm again.
Battery charging
Use a voltage regulated battery charger (constant
voltage). A switched two-stage charger with constant
voltage is recommended. A two-stage charger
automatically reduces the charging voltage (14.4 V)
to trickle charging (13.3 V) when the battery is fully
charged.
Battery storage and trickle charging
Never leave a machine with a discharged battery. A
discharged battery freezes at a temperature of about
-7°C (19F). A fully charged battery will freeze at
-67°C (-89F). A battery that is not being used must
be fully charged before being put aside.
Trickle charging is not normally required during a
period of 6 to 8 months. If a battery has not been in
use for a long period, it must be fully charged before
being used. Trickle charging is recommended a
couple of times during the season (especially in
winter).
Desktop charger
WARNING Explosion
If the battery is charged in a damp room at a high
temperature, it might explode.
►
Use charger only in a dry room within the
temperature range -25-70°C (-13-158°F).
♦
The desktop charger works within a voltage range
of100-240 V.
♦
The desktop charger comes with an adapter that
works in most sockets.
A steady yellow light indicates that the charger is
ready for charging. Place the battery in the charger.
The charger verifies the battery, which takes 10
seconds. If battery is accepted the charge starts. Full
charge time is 2.5 hours at a normal temperature.
The battery will not be damaged if it is left in the
charger when fully charged.
When the battery is removed from the charger, wait
until the LED indicator turns yellow before inserting
a new battery for charging.
