MAINTENANCE – SERVICE POINTS
When removing the battery, always dis-connect the
negative cable first. When fitting the battery,
always connect the positive cable first.
Dispose of the old battery in the approved
environmentally suitable manner – batteries contain
toxic lead.
Do not use a quick-charger when charging the battery.
This may shorten the life of the battery.
When welding on the machine, the positive and
negative terminals of the battery must be disconnected.
Never connect the welder ground to the diesel engine.
Disconnect the cable from the receiver before any
welding on the machine.

Technical data
Model Battery Capacity Max. current HxLxW Weight
LH800 HV44-12 44 Ah/20 hours 660 A (5 sec) 175x197x165 mm 15 kg (33 Ibs)

/3 x 7¾ x 6½ in)
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.
Charging
The battery is normaly charged by the engine generator. If for some reason the battery is
completely discharged, it must be recharged using a battery charger. You can discharge the
battery by not turning back the ignition key after the engine starts, or by starting and stopping the
engine so often that the battery does not have time to recharge normaly.
Cyclical charging of LH batteries using battery charger:
Battery Charging current Charging voltage
HV28-12W max. 8.4 A 14.4–14.7 V
HV44-12 max. 13 A 14.4–14.7 V
NOTE
Use a voltage-regulated battery charger (constant voltage). A switched two-stage charger that has
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 becomes fully charged.
Suitable battery chargers for 230 Volt:
Optima Model RTC 12/7-S-230
LADAC Model LADAC 512
Tudor Model 61715 Tudor
Storage/Trickle charging
A discharged battery will freeze at a temperature of about -7°C (19°F). A fully charged battery will
freeze at -67°C (-88°F). A battery that is not being used should be fully charged before being put
aside. Trickle charging is not normallly required during a period of 6 to 8 months. If a battery has not
been in use for a long period, we recommend fully charging it before use. Trickle charging is
recommended a couple of times during the season (especially in winter).
