8.17 Leisure Battery
A) Type / Selection
For optimum performance and safety, it is
essential that only a proprietary brand LEISURE
battery is used and it is suggested to select a
battery from the NCC Verified Battery Scheme
with a typical capacity of 75 to 120 Ah
(Ampere / hours). Depending on the
prospective use of the vehicle, the correct type
should be selected (A, B or C, according to the
NCC Verified Battery Scheme). A normal car
battery is NOT suitable. This battery should
always be connected when the system is in use.
The PSU is configured to work with standard
lead acid leisure batteries, and in most cases
is also compatible with the latest range of
Absorbed Glass Matt (AGM) batteries. The
system is also suitable for Lithium batteries with
built-in Battery Management Systems BMS.
Before fitting non-standard batteries, please
check that the charging profile described in 8.16
is suitable for the type of battery by referring
to the battery documentation or battery
manufacturer.
Some vehicle installations can cater for two
leisure batteries connected in parallel. In these
cases, it is recommended that two identical
batteries are used.
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 40A
per battery.
B) Installation & Removal
Always disconnect the 230V mains supply
and turn the PSU green charger switch to the
off position (button out) 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) Operation / 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 10V.
Discharging a battery below this figure can
cause permanent damage to one or more of
the cells within the battery.
To prevent over discharge, the power control
system incorporates a battery protect circuit
that warns the users and then disconnects the
batteries when they fall below set values.
If a warning is active a beep will be emitted by
the control panel. To cancel the warning, press
the Levels Button. These warnings will not be
repeated unless the power switch is turned off
and on again. This is to ensure the warning does
not become a nuisance.
