The Battery
A Lead Acid cell system is used in all ‘Wolflite’ Safety Handlamps. A minimum of four hours continuous output is provided for an average of 500
recharging cycles. A common battery pack is used for the H-251 Mk1 and H-251 Mk2. The H-251E battery pack has an encapsulated control and
current limiting circuit, and has been tested for EMC compliance and CE marked accordingly. For optimum performance and safety please observe
the following:
• Charge before first use. Note: Dangerous Goods Regulations
•Avoid deep discharge. Hazardous Materials Regulations
•Recharge immediately when flat. Restricted Articles Regulations
•Recharge every six months when stored.
The US Dept. of Transport, IATA, and CAA declare these batteries are “not regulated”.
Warning: Do not short-circuit or incinerate Do not cut, crush or puncture
Do not recharge other than from Wolf Chargers Dispose of only via licensed disposal agency
Charging ‘Wolflite’ H-251 Mk1 Battery
To remove the battery for charging remove the lens ring (see “To Open the Lamp’’). The battery removal tab is visible and can be used to aid
extraction. WHILE THE BATTERY IS ON CHARGE THE LENS RING MUST BE REPLACED TO PREVENT DUST ENTERING THE LAMP
ENCLOSURE. If available, a spare charged battery can be fitted.
The Battery is charged in a fully automatic charging unit. Indicators show when a battery has been fully charged. AFTER USE, RE-CHARGE AS
SOON AS POSSIBLE.
Charger Unit C-251 for H-251 Mk1
This ‘Wolflite’ Battery Charger is ‘CE’ marked as compliant with Low Voltage and EMC Directives. Before connecting to the mains ensure the
correct voltage is selected and the battery is in the charger, the indicators will show the state of battery charge and charger mode. 90% capacity is
achieved in 4/5 hours. The charger indicators will suffer from electro-magnetic interference when sited less than five metres from sources emitting at
the following frequencies: 103-115MHz, 117-119MHz, 126-136MHz.
Charging ‘Wolflite’ Handlamps H-251 Mk2 and H-251E
The battery is charged within the lamp body. The H-251 Mk2 Handlamp switch must be in the ‘OFF’ position when on charge. The H-251E can
be switched ‘ON’ when charging, the lamp is then set for stand-by power failure mode and will automatically illuminate should power to the charger
be cut. 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 and H-251E
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.
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.
WARNING: THE WOLFLITE CHARGERS ARE DESIGNED FOR CHARGING WOLFLITE HANDLAMPS ONLY – NO OTHER BATTERIES OR
BATTERY OPERATED DEVICES ARE TO BE USED
