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 pulse speed switch position you use
most frequently. Refer to
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 cause battery damage and will necessitate frequent replacement of the battery. 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
