7. Recharging Battery Pack
Battery packs and chargers are not included in the delivery and must be ordered separately. The vehicle is designed
for a battery pack with 6 cells (7.2V).
Please note:
Before a new rechargeable battery pack delivers its maximum power, several complete discharge and
charge cycles are necessary.
Always drive the rechargeable battery pack empty, since recharging a “half-full” rechargeable battery
pack can cause a so called memory effect. This means that the rechargeable battery pack loses its
capacity, it no longer releases all of its saved energy, drive time is decreased.
If you are using several rechargeable battery packs or rechargeable batteries, purchasing a high-quality
charger may be worthwhile. This normally offers a discharge function as well as a fast charge mode for
rechargeable batteries.
Proceed as follows:
• If the battery pack was taken directly from the vehicle and is still hot, wait until it has cooled down before you
recharge it.
• Connect the battery pack with the charger observing the correct polarity. Normally the special design of the two
plugs avoids the incorrect connection of the rechargeable battery.
Do not use any force when plugging it in.
For reasons of safety place the rechargeable battery pack on a non-flammable surface, eg a tiled floor.
Keep the rechargeable battery pack away from flammable objects. Do not charge the battery pack in
the vehicle.
Never recharge the rechargeable battery pack unattended.
The rechargeable battery pack gets warm during charging. This is normal.
• After charging, separate the battery pack from the charger.
• Before using the battery pack in the vehicle, wait until it has cooled down to room temperature.
