CARE AND MAINTENANCE
With only minimal maintenance, the Husky 2/10/55 Battery Charger will deliver years of dependable service.
Follow these simple steps to maintain the charger in optimum condition:
• After each use, clean the battery charger clamps - be sure to remove any battery fluid that will cause corrosion
of the copper clamps.
• Clean the outside case of the charger with a soft cloth and, if necessary, mild soap solution.
• Keep the charger cords loosely coiled during storage to prevent damage to the cords. Do not use the charger if
cords or clamps have been damaged in any way - call Husky Technical Support Department toll-free at
(866) 584-5504 for details on replacing cords and clamps.
TROUBLESHOOTING
Very Cold Battery
If the battery to be charged is extremely cold (in temperatures less than freezing - 0º C/32º F) it cannot accept a
high rate of charge, so the initial charge rate will be slow. The rate of charge will increase as the battery warms.
WARNING: DO NOT attempt to charge a frozen battery.
Sulfated Battery
When batteries are left in a discharged state for a long period of time, they become "sulfated". Sulfated batteries
cannot accept a high rate of charge since the internal plates are coated with lead sulphate. To see if a battery in this
condition can be "saved", take it to a service station or battery distributor for professional evaluation and/or service
.
Short-circuited Battery
• If the battery being charged has been short-circuited, the ammeter will show that the battery has zero charge
level, and that the charger is operating at peak amperage. If, after 5 minutes charging time, the ammeter
reading has not decreased, unplug the charger and discontinue the charging process.
• Using a voltmeter, determine the voltage of the battery and if it is under 12 volts, the battery is probably beyond
repair or recharging, and will need to be replaced.
• If the voltage is over 12 volts, reconnect the charger and resume the charging process for another 15-20
minutes. If, after that time, the ammeter still has not moved towards a lower reading, repeat the voltmeter test.
If the reading is still over 12 volts, there is a problem with the battery that requires professional service or
replacement.
NO AMMETER READING
• Make sure that the charger is plugged into a "live" 110/120 volt AC outlet.
• Unplug charger and check battery connections - ensure that there is a good connection with the battery terminal
and/or vehicle chassis.
• Check to be sure that the battery is not sulfated.
• Check that the correct charge rate has been selected for the battery being charged.
•
Ensure that enough charging time has been allowed for - check table in Appendix for approximate charging times.
• See Pre-charge Battery Activation
AMMETER DISPLAYS A READING, BUT BATTERY IS NOT ACCEPTING CHARGE
• First, make sure that battery is capable of being charged - ensure that it is not sulfated or damaged.
• Refer to Charging Time Table in Appendix to ensure that enough time is being allowed to charge the battery.
