Battery Selection And Management - Tru-Test speedrite Delta 1B Instruction Manual

Battery Selection and Management

This section refers exclusively to re-chargeable, lead-acid batteries, for example car, tractor, truck, marine or specialist
deep-cycle batteries.
The battery you select will depend on whether your installation is a battery-only or a solar installation. For both types
of installation, the position of the energizer selector switches will determine the size of battery and solar panel
required. Refer to Operation on page 2 for an explanation of the function of the selector switches.
Battery selection for a battery-only installation
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 Medium charge level. For more information on testing battery charge level, see
Battery test setting on page 4.

Battery selection for a solar installation
The battery and solar panel must be selected carefully to suit the energizer's electrical current consumption. This will
depend on the position of the energizer selector switches, the energizer model being used and the amount of
sunshine at the location of the installation.
As a guide, the minimum amp hour (Ah) rating of the 12 V lead-acid battery required for each model is shown below.
This table is based on average usage over seven days with no sunlight. It takes into account the variety of solar panel
and regulator types that could be used in a solar installation. For more detailed information, refer to the "Speedrite
Solar Selection Guide".
