Battery selection for a battery-only installation
As a guide, the amp hour (Ah) rating of the 12 V rechargeable batteries
required 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
12 V rechargeable battery and to recharge it when it is half discharged.
For more information on checking the battery voltage, see

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 little or 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 www.tru-test.com.

Battery management
Warning!
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 charging
Warning!
- Do not attempt to recharge a non-rechargeable battery.
- When recharging a battery, ensure that there is adequate
ventilation to allow gases to disperse.
Regular recharging of the battery is essential. Use a suitable safety
approved battery charger and refer to the battery manufacturer's
recommendations.
1 Attach the positive (+) battery charger lead to the positive
terminal of the battery, and the negative (–) battery charger lead
to the negative terminal on the battery.
2 Connect the battery charger's input power plug to a mains or line
socket and turn on the power supply.
Caution!
exceed the recommendations of the battery manufacturer on
recharging the battery from a mains-powered (line-powered) source.
Battery care and maintenance
House the battery in a suitably designed battery box, if the battery
•
is likely to be exposed to the weather.
When not in use, store the battery fully charged and recharge at
•
regular intervals (every 8 weeks).
Recharge a discharged battery as soon as possible. Batteries
•
should not be left discharged.
Inspect the battery regularly to ensure that the electrolyte level
•
does not fall below the surface of the battery plates.
Top up the battery using distilled water. Do not overfill. Refer to
•
the battery manufacturer's recommendations for more
information.
