Battery selection and management
This section refers exclusively to rechargeable, lead-acid batteries, for example car, tractor, truck, marine or
specialist deep-cycle batteries.
The size of battery you select will depend on the model of energizer you have and the Selector switch
position you use most frequently. Refer to
Selector switch.
Battery selection
As a guide, the amp hour (Ah) rating of the 12 V lead-acid battery required for each model is shown below.
This table is based on a 21 day operating period between battery charging. Although operating time can
exceed 21 days, this is likely to reduce the life of the battery and necessitate frequent replacement of the
battery. For a description of how the energizer prolongs the battery life, see
For best system reliability and long term battery life, the preferred battery and charging regime is to use a
deep-cycle, lead-acid battery and to recharge it when it has discharged to about half-way. For more
information on testing battery charge level, see

Battery management
Warning!
Batteries contain harmful chemicals and when used incorrectly, may cause injury. Observe
the guidelines for battery care, maintenance and safety in this manual and in the documentation
supplied with your battery.
Battery preservation
In order to extend the operating period between battery charges, the energizer will begin to operate at a
slow speed and half output energy when the battery capacity drops below approximately 40%.
In order to prevent deep discharge and thus irreversible damage to the battery, the energizer will stop
producing output pulses when the battery capacity drops below approximately 20%.
