Battery Charging Instruction Sheet
This instruction sheet contains important safety and operating instructions for model HPX-10 battery charger.
Before using the battery charger, please read all instructions and cautionary information on the battery charger
and the product using the battery.
• Do not expose the charger to rain or moisture
• Do not remove the cover
• Disconnect charger from AC power before maintenance or cleaning
• Charge only sealed or valve regulated, lead-acid, non-automotive, maintenance free
rechargeable batteries
• Enclosure may be hot during charging - Do Not Touch
• Where hydrogen gas may be present, disconnect unit from AC power before connecting or
disconnecting output connectors
Introduction
The HPX-10 is a two stage, constant voltage battery charger with current limiting, current fold back, and
automatic temperature compensation of the output voltage. It is protected against shorting and reversing the
output terminals on a battery. There is one indicator light. It lights green to indicate when power is applied, there
is a battery attached, or that the charger is in float mode. It lights yellow when the unit is charging a battery. A red
light indicates a fault condition (short/reversed output connector).
This unit is designed to automatically switch into a single stage, float charge mode when the battery is charged. A
single stage, parallel charger version is available for maintaining full charge on a battery when used with a
permanent or intermittent parallel load. This unit is not designed to be used as a standalone power supply.
Operation
This section contains instructions for operating the battery charger.
1. Connect the power cord to a properly grounded outlet supplying the correct input voltage. The indicator
light should be green.
2. Plug the connector from the battery into the connector on the battery charger.
NOTE : Ensure that the “keys” on each connector line up.
The indicator light will be yellow until the battery is 95% charged. The light will then change to green, indicating
that the battery may be used again. For 100% charge, the battery should remain connected to the charger for an
additional three hours.
Charging tips
For safer and more efficient charging, batteries should be charged with higher voltages when cold and lower
voltages when warm. The HPX-10 incorporates automatic temperature compensation of the output voltage. For
this feature to work properly, the battery and the charger need to be stabilized at the same temperature.
