Husqvarna HUV4210-GXP - Manual (Page 39)

Batteries – Electric Vehicles
1. The batteries should be kept clean and free of corrosion. Wash tops and terminals of batteries with a solution
of baking soda and water (1 cup (237 mL) baking soda per gallon (3.8 L) of water). Rinse solution off of the
batteries. Do not allow this solution to enter the battery. Be sure terminals are tight. Let the terminals dry and
then coat with Battery Terminal Protector Spray (Husqvarna 603 00 00-03). See following NOTE.
NOTE: Dispose of waste water properly.
2. The electrolyte level in the batteries should be checked weekly (Figure 20). Add water only after charging unless
the electrolyte level is below the top of the plates. In this case, add just enough water to cover the plates, charge
and then check the level again. Never charge batteries if plates are exposed above electrolyte level. For best
battery life, add only distilled water. See following CAUTION and NOTE.
CAUTION
• Do not overfill the batteries.
NOTE: A battery watering gun or bottle is available at many auto parts dealers.
3. The hold-down straps should be tight enough so that the batteries do not move while the vehicle is in motion,
but not so tight as to crack or buckle the battery case. Tighten hold-down retaining nuts to 40 in-lb (4.5 N·m).
The terminal connections should be clean and tight, and any worn insulation or frayed wires should be replaced.
Tighten battery terminals to 110 in-lb (12.4 N·m). See following WARNING.
WARNING
• If battery wire terminals are damaged or corroded, replace or clean them as necessary. Failure to
do so may cause them to overheat during operation and could result in fire, property damage, or
personal injury.
4. After use, the batteries should be placed on charge. The batteries should never be left discharged any longer
than absolutely necessary (do not leave discharged overnight).
