11. Battery Removal.

Should a problem occur which would indicate a battery fault; each

battery should be tested to find the faulty cell. Industry standard

devices such as the Alpha Bat tester can be used to give a percentage

of the battery’s true capacity rating.

ALWAYS charge the scooter fully before undertaking any battery

tests.

DO NOT use devices that are designed for use with automotive type

batteries. These are not designed to test deep cycle batteries used

with scooters and can cause permanent damage to a battery.

A simple test to indicate a possibly failed battery is to run the scooter

under load and take a voltage reading of each battery with a

multimeter. To do this, remove the shroud covering the batteries and

connect the multimeter to one of the batteries. Re-fit the seat and

drive the scooter a small distance. The battery voltage should not fall

lower than about 11 volts. Repeat the test for each battery.

Overall system power can be

tested via the charge socket

with a multimeter. Switch the

scooter on and carefully place

the multimeter probes in the

corresponding sockets (1 & 2)

as shown in the image. A fully

charged scooter should give a

reading between 25 & 26

volts.

Ensure the multimeter is set

to measure voltage. DO NOT

short circuit poles 1 & 2.
