STORAGE BATTERY
ENGINE OVERHAUL
4.
Check the polarity to be sure the battery is not reversed with respect to the generating system.
5.
Connect the grounded terminal of the battery last to avoid short circuits which will damage the
battery.
Servicing the Battery
A battery is a perishable item which requires periodic servicing. Only when the battery is properly cared for as
described below can long and trouble free service be expected.
1.
Check the level of the electrolyte regularly. Add water if necessary, but do not overfill. Overfilling
can cause poor performance or early failure.
2.
Keep the top of the battery clean. When necessary, wash with a baking soda solution and rinse
with fresh water. Do not allow the soda solution to enter the cells.
3.
Inspect the cables, clamps and hold down bracket regularly. Clean and reapply a coat of grease
when needed. Replace corroded or damaged parts.
4.
Use the standard battery test as the regular service test to check the condition of the battery.
5.
Check the electrical system if the battery becomes discharged repeatedly.
Many electrical troubles caused by battery failures can be prevented by systematic battery service. In general,
the care and maintenance recommendations for storage batteries are the same today as they have always
been.
Battery Safety Precautions
When batteries are being charged, an explosive gas mixture forms beneath the cover of each cell. Part of this
gas escapes through the holes in the vent plugs and may form an explosive atmosphere around the battery
itself if ventilation is poor.
WARNING
Explosive gas may remain in and around the battery for several hours after it has
been charged. Sparks or flames can ignite this gas causing an explosion which
could shatter the battery. Flying pieces of the battery structure and splash of
electrolyte can cause personal injury.
