9. The battery terminals need to be checked regu-
larly for signs of corrosion. If any corrosion is found,
then clean the terminals completely and re
-
grease
the terminal using Vaseline petroleum jelly, never
use ordinary grease. Ensure that the terminal nut
and bolt, cable clip and exposed cable are com-
pletely covered with jelly.
10. Following all the points above should result in a
healthier battery, greater range for the vehicle user
and a longer life for your batteries.
11. When your batteries no longer hold a charge,
return them back to your Authorised Dealer, your
local authority recycling centre or Horizon Mobility.
Please always dispose of your batteries responsibly.
17.6. General charger information
The external charger has been designed to charge
two 12V GEL or AGM VRLA type batteries connected
in series (= 24 V).
17.7. Charger safety features
Your charger has features which prevent hazards or
accidents occurring as a result of connecting the
batteries the wrong way round, overheating caused
by fault conditions or attempting to charge wrong
voltage batteries.
The majority of charger sizes are electrically double
insulated and no earth connection is required. Some
larger sizes may be electrically earthed and this will
be clearly stated on the label.
The fused 3 pin UK mains input plug has the rating
of this fuse shown on the plug or charger label.
DANGER!
As with all mains powered electrical equipment, al-
ways replace blown fuses with the same type and
size of fuse as specified.
Fitting a different fuse can result in an increased fire
risk, damage to the charger or failure of the charger
to operate properly.

17.8. Procedure for connecting the charger
See Section 12, Quick Start Guide for instructions
For more information about the charger operation,
consult the instructions provided with the charger.
NOTE:
If the battery charger is not connected to the
scooter, it does not output any charge voltage.
The charger may be used with other brands of GEL
type VRLA batteries, subject to written confirmation
from the Horizon Mobility Limited.
DANGER !
An extension cord should not be used unless it is
absolutely necessary. Use of an improper extension
cable could result in a risk of fire and electric shock.
If any extension cable must be used, make sure the
pins on the plug of the extension cord are the same
number, size and shape as those of the plug on the
charger; and that the extension cable is properly
wired with an earth connection and in good physical
and electrical condition.
WARNING !
Always switch off at the mains power before you
disconnect the charger from the batteries.
The charger is designed for indoor use. Do not use
outdoors or expose to rain, snow, spray or any form
of moisture.
CAUTION !
When buying replacement batteries or a charger
always consult your Authorised Service Agent or
Horizon Mobility Limited.
Never leave the battery charger connected to the
batteries with the mains disconnected or switched
off. This could result in permanent damage to your
batteries caused by them being deep discharged
over a period of time.
To reduce the risk of damage to the electrical plug
and cable, always disconnect by pulling the plug
casing rather than the cable when disconnecting the
charger.

Note: Battery myths
Over the years, battery technology has improved
but, unfortunately, a lot of advice given on caring
for your batteries has not. The result is a number of
confusing and contradictory instructions on the best
way to care for your batteries.
Batteries are the power source for all mobility vehi-
cles available today. The design of the batteries
used in mobility vehicles is significantly different
from the batteries used to start a car for example.
Car batteries are designed to release a large amount
of power over a short period of time, whilst mobility
batteries (commonly called deep cycle batteries)
release their power evenly, over a long period of
time. Therefore, due to lower production volumes
and increased technology required, mobility batter-
ies are usually more expensive.
Never fit car or other none deep cycle type batteries
to a mobility vehicle. Fit only deep cycle, mainte-
nance free mobility batteries, these do not have a
wet acid base and a much safer from spillage.
