Important PointsThe electrolyte (diluted sulfuric acid) is very toxic. DO NOT allow acid to splash onto clothes, the skinor eyes to protect them from burning. Eye contact with acid may cause blindness. In case of contact

with the acid, use a large amount of clean water to ush and rinse the areas in which the acid cameinto contact. See a Physician immediately. If the electrolyte acid gets into clothes, it will permeate tothe skin. Remove tainted clothes immediately and then put them in water to rinse.

The batteries can withstand numerous cycles of charging and discharging as long as it is not left in adischarged condition for a long period of time.

If one of the batteries are overcharged, it can be detected by close inspection of the battery itself.If the battery is exposed to an extreme overcharged condition, it can break down and short circuitinternally. In this condition, the battery will produce zero voltage under all load and charge conditions.An overcharged battery can boil off the electrolyte solution. This problem can be due to excessivetime on a battery charger or a failed voltage regulator.

If the scooter is left to sit for a long time or is stored, the battery will slowly discharge. It isadvisable to recharge the battery before attempting to start the scooter after a period of storage.

When lling a new battery with acid, allow it to sit and breath for fteen minutes before installing itinto the scooter or charging it. It is advisable to charge a new battery after lling with acid eventhough it may appear to have sufcient charge.

When working on the scooters electrical system, make sure that the main switch is turned offand/or the battery is disconnected. Disconnecting and reconnecting of live circuits can cause highinstantaneous currents that can damage the battery and cause injury.

Any short-circuiting of the wiring can cause damage to the battery.
