8.1 Motorhome battery
Your motorhome has been fitted with a sealed,
Absorbed Glass Matt leisure battery which is
specially designed for installing on its side and
without ventilation. The battery should only
be positioned in the compartment under the
driver’s seat, and be properly secured before
travelling.
It is recommended that a good quality leisure
battery is always connected when the
motorhome electrical system is in use.
Leisure batteries are a deep cycling
rechargeable heavy duty 12v battery designed
to provide power for lights and other electrical
appliances. Replacement batteries should be a
proprietary brand leisure battery with a 85amp -
110 amp capacity.
WARNING: When renewing a leisure
battery care should be taken ensuring that
a fully sealed Absorbed Glass Matt battery,
which can be fitted on its side is used. IF
UNSURE SEEK ADVICE Other types of leisure
batteries contain a liquid and electrolyte
which will leak out if laid on its side. CONTACT
WITH THE LIQUID ACID CAN CAUSE SEVERE
INJURIES AND DAMAGE TO THE VEHICLE.
Note: Replacement batteries should be
checked dimensionally before purchasing,
to ensure fitment within the battery
compartment, as brands vary in size.
It should be remembered that batteries suitable
for the electrical demands of a motorhome
differ in design from those for use with a car,
and whilst the system may operate with a car
battery it is strongly recommended that only a
rechargeable leisure type battery, maintained in
good condition is used.
WARNING: When connecting the battery,
ensure that the correct polarity is observed
(black is negative and red/brown is positive)
and that the terminals are securely fastened.
Under normal circumstances it should not be
necessary to remove the battery other than for
routine inspection of terminals.
Your motorhome has been fitted with an in-line
40 amp fuse between the battery terminal
and the power supply unit. Do not use a higher
rated fuse as this may cause damage to your
motorhome.
WARNING: Switch off all appliances and
lamps before connecting or disconnecting
the battery. Open flames and smoking are
prohibited around the battery compartment.
To preserve the life of your leisure battery and
charger please observe the following:
1. Do not leave all 12v lights powered at the
same time as this will drain your leisure
battery more rapidly.
2. If all 12v lights must be powered together,
ensure the battery is ‘in-circuit’ and that the
battery charger is turned on.
3. For optimum performance use the
transformer/charger unit with a leisure
battery attached.
Please note the auxiliary battery or batteries
supplied with your motorhome may not be fully
charged and should be charged for a minimum
of 24 hours before use.
Battery performance may be affected by a
number of things such as ambient temperature,
age, state of charge etc.
WARNING: It is imperitive that the battery
is correctly secured as any movement could
cause wear to the casing and cause electrolyte
to leak.
WARNING: For your own safety do not
store anything other than the leisure battery in
the battery compartment under the
driver’s seat.
