Looking after your Mobility Scooter Batteries
How you look after your batteries will affect both the distance you can travel and how long the batteries will last before they must be replaced.
- Fully recharge your batteries after every use of the vehicle.
- Charging batteries for an hour or so, now and then, will drastically reduce their lifespan.
- Do not disconnect the charger as soon as the full charge light illuminates. Leave the charger connected and switched on at the mains for at least a further two hours.
- Fully charged batteries can last for years but if you run them totally flat once and they might never regain full power.
- Batteries will go flat if simply left without charging.
- Batteries do not give full power or charge up well in very hot or cold weather.
- Batteries can only be properly tested on a workshop battery tester. Depending on the size and condition of the batteries this may take several hours.
- Only use the charge supplied with your vehicle. Chargers may look alike and have identical connector plugs but they can have vastly different power outputs, and this will affect the charging and may even damage the vehicle.
- If batteries are allowed to go totally flat, and then a charger is connected, the charger may indicate a full charge, usually a green light. This does not mean that the batteries are full, simply that the charger has done the best that it can. The vehicle may drive but only for a vastly reduced range.
- Continuing to charge flat batteries in an attempt to recover them can be dangerous.
- Never leave a charge connected to the batteries without the mains switched on.
- Never use a battery charger designed for car batteries on a mobility vehicle battery.
The range of mobility vehicles is calculated by the manufacturer using I.S.O Standard 7176, part 4: scooter energy consumption theoretical range. This is an indication of the theoretical maximum range of the vehicle. This can be reduced by any one or a combination of the following;
- User weight greater than 100 kgs
- Incorrect or insufficient charging
- Batteries whose age and condition are less than perfect
- Terrain that is hilly, sloping, muddy, gravel, sand, grass, snow or ice
- The vehicle climbs ramps regularly
- The temperature is very hot or cold
- Damage to one or more tyres
- Lack of servicing/lubrication
- Lots of start/stop driving
- Thick pile carpets
