3.3 Battery
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.
Installation & Removal
Always disconnect the 240v mains
supply and turn the PSU 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.
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.
Even when plugged into the mains
supply, should you choose to use all
12V lighting and services
simultaneously, there is the potential
on certain models, in certain
conditions, of consuming more 12V
energy than the on board charger can
replace.Whilst this is not a problem in
the short term, over a longer period
of time the leisure battery could
become discharged.
In normal operating conditions
however, the battery will be charged
either overnight (when all lights are
turned off), or when the vehicle is
being driven (via the alternator).
