This battery charger is designed for
Use with Lead Acid or VRLA battery packs.
Batteries can be dangerous, do not place metallic
objects across the terminals of a battery or battery
pack. When handling batteries remove all loose
jewellery, watches and rings. Take care not to place
tools across the terminals. Only specified types of
batteries should be used with this unit as charging
others may cause damage and result in serious injury.
Before using this unit, ensure the following: -
Unit is physically checked, in event of any damage to
unit please return to supplier.
AC Voltage is correctly selected where appropriate.
Read and follow the “How To Use” guidelines in this
instruction document.
It is recommended that when using the SM82 battery
charger, the battery packs should be at ambient
temperature (20deg C) before starting charge.
Consult Table (A) to determine whether to use float
mode (with manual boost option) or Auto-3 Stage
mode.

Note: Auto-3 Stage Operation is controlled by output current of the charger, this
determines whether charger goes into an increased 'boost' voltage mode,
continous charging at this voltage causes gassing of batteries and shortens
both AH capacity and life, having a continous (standing load) above this level
whilst in the Auto-3 Stage Mode will cause the charger to be in a continous
'boost' mode.
