6H-4 CHARGING SYSTEM
Care of battery
1) The battery is a very reliable component, but needs periodi-
cal attentions.
• Keep the battery carrier clean
• Prevent rust formation on the terminal posts
• Keep the electrolyte up to the upper level uniformly in all
cells.
When keeping battery on vehicle over a long period of time, follow
instructions given below.
• Weekly, start the engine and run it until it reaches normal
operating temperature with engine speed of 2000 to 3000
rpm.
Make sure all electric switches are off before storing the
vehicle.
• Recharge the battery twice a month to prevent it from dis-
charging excessively. This is especially important when
ambient temperature is low.
The battery discharges even when it is not used, while vehi-
cles are being stored. Battery electrolyte can freeze and bat-
tery case can crack at cold ambient condition if battery is not
properly charged.
2) Keep the battery cable connections clean.
The cable connections, particularly at the positive (+) termi-
nal post, tend to become corroded. The product of corrosion,
or rust, on the mating faces of conductors resists the flow of
current.
Clean the terminals and fittings periodically to ensure good
metal-to-metal contact, and grease the connections after
each cleaning to protect them against rusting.
3) Be always in the know as to the state of charge of the bat-
tery.
The simplest way to tell the state of charge is to carry out a
hydrometer test. The hydrometer is an instrument for mea-
suring the specific gravity (S.G.) of the battery electrolyte.
The S.G. of the electrolyte is indicative of the state of charge.
Refer to “Diagnosis” of “Battery” in this section.
WARNING:
• Never expose battery to open flame or electric spark
because of battery generate gas which is flammable
and explosive.
• Do not allow battery fluid to contact eyes, skin, fabrics,
or painted surfaces as fluid is a corrosive acid. Flush
any contacted area with water immediately and thor-
oughly.
• Batteries should always be kept out of reach of chil-
dren.
