3.3 BATTERY
A) Type / Selection
For optimum performance and safety it is essential that only a proprietary brand LEISURE battery is
used with a typical capacity of 75 to 120 Ah (Ampere / hours). A normal car battery is NOT suitable.
It is recommended that the leisure battery is always ‘in circuit’ when the system is in use.
The battery feed is fitted with an inline fuse between the battery and the electrical harness, and is
usually located immediately outside the battery compartment or within 500mm of the battery. The
maximum rating of this fuse is 20A.
B) Installation & Removal
Always disconnect the 240v mains supply and turn the PSU 2007 charger switch to the OFF (0)
position before removing or installing the battery.
When connecting the battery, ensure that the correct polarity is observed (black is negative [-] and red
is positive [+]) and that the terminals are securely fastened. Crocodile clips must not be used.
WARNING
Explosive gases may be present at the battery. Take care to prevent flames and sparks in the vicinity
of the battery and do not smoke.
C) Servicing
Under normal circumstances it should not be necessary to remove the battery other than for routine
inspection of the terminals and “topping up” of the battery fluid where applicable. Please see
instructions supplied with the battery.
Note: Do not over-discharge the battery. One of the most common causes of battery failure is when
the battery is discharged below the recommended level of approximately 10.5v. Discharging a battery
below this figure can cause permanent damage to one or more of the cells within the battery.
