Battery selection and
management
This section refers exclusively to 12 V rechargeable batteries.
The batteries you select will depend on whether your
installation is a solar or a battery-only installation. For both
types of installation, the selector switch position you use most
frequently will be a factor. Refer to
explanation of the function of the selector switch.
Battery selection for a battery-only
installation
As a guide, the ampere hour (Ah) rating of the 12 V
rechargeable batteries required is shown below. This table is
based on a seven day operating period between battery
charging. Although operating time can exceed seven 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 12 V rechargeable battery and to recharge it when it is
half discharged.

WARNING!
12 V rechargeable batteries must be used.
Battery selection for a solar
installation
The battery and solar panels must be selected carefully to suit
the energizer's electrical current consumption. As well as the
position of the selector switch position, the battery and solar
panels you choose will depend on the amount of sunshine at
the location of the installation.
As a guide, the minimum amp hour (Ah) rating of the 12 V
rechargeable battery required is shown below. This table shows
the battery requirements for up to seven days of operation with
