2. Remove the battery from the vehicle.
3. Inspect battery carrier for damage caused by loss of acid from the battery. If
acid damage is present, it is necessary to clean area with a solution of clean
warm water and baking soda. Scrub area with a stiff bristle brush. Wipe clean
with a cloth moistened with ammonia or baking soda in water.
4. Clean the battery, especially the top with same solutions as described in step 3.
5. Inspect the battery case and cover for cracks. If cracks are present, battery must
be replaced.
6. Clean the battery post with a suitable battery post cleaning tool.
7. Clean the inside surfaces of the terminal clamps with a suitable battery
terminal cleaning tool. Replace damaged or frayed cables and broken terminal
clamps.
8. Install the battery in the vehicle.
9. Connect the positive and negative cables to the battery in the order of mention.
10. Tighten the clamp nut securely. BATTERY CHARGING Battery electrolyte temperature may temporarily be allowed to rise to 55°C (131°F).
Increase of electrolyte temperature above 55°C (131°F) is harmful to the battery,
causing deformation of battery cell, decrease in life of battery, etc.
case is cracked or leaking to protect hands from
the electrolyte. A suitable pair of rubber gloves
(not the household type) should be worn when
removing battery by hand.
WARNING:When batteries are being charged, an explosive gas
forms beneath the cover of each cell. Do not smoke
near batteries on charge or which have recently
been charged. Do not break live circuits at the
terminals of the batteries on charge. A spark will
occur where the live circuit is broken. Keep all open
flames away from the battery.
