MINERAL CONTENT
For the longest battery life, use distilled water in batteries. However, if tap water is going to be used, be sure the
mineral contents are below these levels:
VIBRATION DAMAGE
The battery hold-downs should always be tight enough to keep the battery from bouncing. Battery life may be
severely shortened if the battery hold-downs are too loose. Hold-downs should be tightened to 40 in.lb (4.5 N-m).
Excessive vibration causes the plates to shed prematurely and shortens the life of the battery. It may also cause acid
to leak out of the vent caps and corrosion to build up on surrounding metal parts. The acid which is lost reduces the
capacity of the battery and cannot be replaced. Battery hold-downs should NOT be so tight as to crack or buckle the
battery case. This may cause leaks which would dry up a cell or cause internal shorts. See Replacing Batteries,
Page 13-4.
