12.5 Maintenance free batteries
This type of battery uses a method of carrying the electrolyte
commonly referred to as ‘gel’, that is held within the battery
case. As the name implies, no maintenance is required other
than regular charging. You can safely transport this type of
battery without fear of acid spilling. Furthermore, they are
approved for transportation on aircraft, trains and ships.
12.6 Battery care
Below is set out a battery care plan for maintenance free
batteries. This has been agreed between Sunrise Medical and
the battery manufacturers, to enable you to get the best out of
your batteries. If a different care plan is followed, this may
result in lower than expected performance from your mobility
vehicle.
12.7 Maintenance free battery care plan
CAUTIONS!
1. Only use an approved Sunrise Medical charger compatible
with the vehicle to be charged.
2. Charge your batteries every night, regardless of the amount
of use your mobility device has had during the day.
3. Do not interrupt the charging cycle.
4.If your mobility device is not required for use, it should
remain connected to the charger until required. This will not
damage your batteries, as long as the mains socket/plug is left
switched on. Turning the mains socket/plug off, but leaving
the mains cable plugged in will eventually deplete your battery
charge.
5. If you leave your vehicle for an extended period (more than
15 days) charge the batteries fully and then disconnect the main
battery lead.
6. Failure to allow for recharge will damage the batteries and
can lead to shortened distances and premature failure.
7. Do not top up the charge of your batteries during the day.
Wait until the evening for a full overnight charge.
8. As a general rule, maintenance free batteries take longer to
fully charge than “wet” lead acid batteries.
9. The battery terminals need to be checked regularly for signs of
corrosion. If any corrosion is apparent, then clean the terminals
completely and re-grease the terminal using Vaseline petroleum
jelly, not ordinary grease. Ensure that the terminal nut and bolt,
cable clip and exposed cable are completely 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. Return the batteries back to Sunrise Medical or directly to
the battery manufacturer for recycling, when they no longer
hold charge.
12.8 General charger information
The external charger has been designed to charge two 12V Gel
type batteries connected in series (= 24 V).
12.9 Charger safety features
The chargers have features which prevent hazards or accidents
occurring as a result of connecting 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 3 pin UK mains input plug contains a replaceable fuse. The
rating of this fuse is shown on the charger label.
DANGER!
As with all mains powered electrical equipment, always replace
blown fuses with the same type and size of fuse as specified.
Fitting of different fuses can result in an increased fire risk,
damage to the charger or failure of the charger to operate
properly.
If your charger has been specified for use in Continental Europe
it will contain a European two pin plug which does not have a
fuse. In this case the fuse is located in the fascia panel of the
charger.
