Charging ‘Wolflite’ Handlamp H-251 Mk2
The battery is charged within the lamp body. The H-251 Mk2 Handlamp switch must be in the ‘OFF’ position
when on charge. Indicators show the state of charge of the battery. Red only indicates the Lamp has not made
correct contact, the Lamp must be pushed firmly until latched in position.
Lamp Chargers for H-251 Mk2
Two types of Lamp Chargers are available – HIGH VOLTAGE and LOW VOLTAGE, to suit fixed or mobile
applications. The chargers are ‘CE’ marked as compliant with Low Voltage and EMC Directives.
Wolflite Charger C-251HV is for mains AC input voltages of 200-240 volts at 50-60 Hz (Off-shore
platform voltages of 254 volts at 60 Hz), user switchable to 100-120 volts at 50-60 Hz. Failure to
select the correct voltage may cause damage. Charger achieves 90% recharge in 6/7 hours. Only
fit manufacturer’s specified fuse. Chargers are fitted with Approved plugs, refer to sales literature
for details.
Wolflite Charger C-251LV is suitable for use from DC supplies of 12 to 32 volts. A full recharge
from a 12 volt supply takes 20/24 hours, but from a 24 volt supply 10/12 hours. The two-core flex
is red, positive and black, negative.
Both chargers are fully automatic, stepping to a safe trickle charge level after the main charge is completed.
Standby continuous long-term charging
On continuous charge a ‘detailed’ inspection of the handlamp should be carried out every 12 months,
in accordance with IEC 60079-17. Particular attention should be given to evidence of terminal corrosion
and resultant acid droplets that might begin to occur after 3-5 years on standby charge. If such evidence
occurs, the battery should be replaced in accordance with these instructions.
A regime of charger switching may extend battery life to up to 10 years, the cycle suggested is: 2 weeks
ON, 2-3 months OFF, etc. Self discharge over the 2-3 months ‘OFF’ period will not be significant.
NOTE: A fully discharged battery must be charged immediately to avoid damage.
The charger contacts are of low voltage output and short circuit protected.
Charger operating ambient: +10°C to +25°C.
