Battery test setting
When the energizer is connected to a battery and the pulse speed switch is set to 'Fast with Battery Test' ( ) the
Indicator lights show the charge level of the battery. The battery test is only relevant when a lead-acid battery is used.
Lights
Battery-only installation
Excellent battery charge level (90-100%):
• No action required.
Very good battery charge level (70-90%):
• No action required.
Average battery charge level (40-70%):
• Monitor battery charge level.
• Recharge the battery to avoid long-term damage to the battery.
Poor battery charge level (20-40%):
• Monitor battery charge level.
• Recharge the battery to avoid long-term damage to the battery.
Very poor battery charge level (0-20%):
• Recharge the battery immediately.
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
Operation on page 4 for an explanation of the function of the pulse speed 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 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
Battery test setting above.
