MAINTENANCE

Tennant 5300 (03–98)

Never add acid to the batteries, only distilled

water. Always keep the battery caps on, except

when adding water or taking hydrometer readings.

Measuring the specific gravity using a hydrometer

is a way to determine the charge level, and

condition of the batteries. If one or more of the

battery cells test lower than the other battery cells

(0.050 or more), the cell is damaged, shorted, or

is about to fail.

NOTE: Do not take readings immediately after

adding distilled water. If the water and acid are not

thoroughly mixed, the readings may not be

accurate. Check the hydrometer readings against

the following chart to determine the remaining

battery charge level:

SPECIFIC GRAVITY BATTERY

at 27_ C (80_ F) CHARGE

1.265 100% Charged

1.223 75% Charged

1.185 50% Charged

1.148 25% Charged

1.110 Discharged

NOTE: If the readings are taken when the battery

electrolyte is any temperature other than 27_ C

(80_ F), the reading must be temperature

corrected. Add or subtract to the specific gravity

reading 0.004, 4 points, for each 6_ C (10_ F)

above or below 27_C (80_ F).

CHARGING THE BATTERIES

1. Drive the machine to a flat, dry surface in a

well-ventilated area.

2. Turn the machine power off and set the

parking brake if your machine has this

option.

FOR SAFETY: Before leaving or servicing

machine, stop on level surface and turn off

machine.
