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. Certain electrical appliances (eg L.C.D. television
monitors) are more susceptible to voltage variations than
others, and may not function correctly if the battery is low
or in poor condition.
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).
