Charging batteries

When should the batteries be charged?
How frequently you need to charge the batteries in your wheelchair depends on
a number of factors, including how you use your wheelchair, the temperature
and age of the batteries and how they are made. All batteries also gradually lose
capacity as they age.
The most important factor for the life of the batteries is how much power is taken
out of them before they are charged and how often they are charged/discharged.
To achieve the best life, the batteries should not be discharged completely.
Always charge the batteries immediately after they have been discharged.
If the battery voltage indicator shows that the batteries appear to be losing power
faster than normal, the batteries may be worn out and need to be replaced.
WARNING
Use only the charger supplied with your wheelchair or recommended by Permobil. Using other
chargers may damage the batteries, the wheelchair electronics or the charger itself. It may also
result in parts becoming overheated, which may entail a greater risk of fire.
Be careful when using metal objects when working with batteries. A short-circuit can easily cause
an explosion. Always use safety gloves and safety goggles.
You may only use a charger with a maximum charging current of 10 A (average)
(the effective value of the charging current must not exceed 12 A).
The batteries must be charged in a well-ventilated room, not in a wardrobe. The batteries must not
be charged in a bathroom or wetroom.
If you want to interrupt the charging process, the mains voltage should be switched off before the
charging contact is disconnected from the wheelchair's charging socket. This is to avoid sparking
and unnecessarily high wear on the charging contact.
The charger's charging cable must not be extended.
The charger may get hot and must not be covered. The charger must be placed so that it has free
space on all sides.
The charging contact must be replaced if it is damaged or gets hot during charging. Both the con-
tact on the charger's cable and the wheelchair's charging socket should be replaced if one part is
damaged or worn. The contacts must be replaced by qualified personnel.
