Battery Maintenance
•
The batteries for this vehicle have high current, high capacity, and a long
lifetime. To keep the vehicle in good performance, it is very important to
maintain it in the correct procedure.
•
The connectors on the batteries are the output connectors. Keep the area
clean and dry, with no foreign matter or dust on it. Proper care will ensure
batteries’ performance and longevity.
•
WARNING: Do not use tap water when filling cells. Use distilled water only!
•
Check the height of the electrolyte periodically. Check it once per week in
summer and once every two weeks the rest of the year. Standard height
level is 10-15mm (½“) higher than the battery plate. If is too low, please
add the recommended distilled water.
•
Keep the wiring well-connected. After using the vehicle initially for 2-3
days, the completed inspection for all connectors should be carried out.
Inspect the vehicle once a week following. Any loose or rusty connectors
should be fixed. Loose or rusty connectors can cause high temperature,
damage, or possible sparking.
•
NOTE: Don’t over-tighten terminals!
•
Charge the battery immediately after discharge, or it will affect the battery
life. Charge the batteries that are in long storage or non-fully charged sep-
arately.
•
Keep the filling-water container clean, so no impurities will be put into the
battery.
•
When the environment temperature is under -40° F, the density of the elec-
trolyte after charging is 1.28 - 1.29 g/cm3. If it is more than 1.30 g/cm3, the
battery can be damaged badly. Add water immediately to keep the elec-
