BATTERIES
FOR SAFETY: Before servicing machine, stop on
level surface, turn off machine and remove key.
The lifetime of the batteries depends on their proper
maintenance. To get the most life from the batteries;
Do not charge the batteries more than once a day
S
and only after running the machine for a minimum of
15 minutes.
Do not leave the batteries partially discharged for
S
long period of time.
Only charge the batteries in a well-ventilated area to
S
prevent gas build up. Charge batteries in areas with
ambient temperatures 80_F / 27_C or less.
Allow the charger to complete charging the batteries
S
before re-using the machine.
Maintain the proper electrolyte levels of flooded (wet)
S
batteries by checking levels weekly.
Your machine is equipped with either flooded (wet)
lead-acid or maintenance-free batteries supplied by
Tennant.
FOR SAFETY: When servicing machine, keep all
metal objects off batteries. Avoid contact with
battery acid.
MAINTENANCE-FREE BATTERIES
Maintenance-free (Sealed AGM) batteries do not
require watering. Cleaning and other routine
maintenance is still required.
FLOODED (WET) LEAD-ACID BATTERIES
The flooded (wet) lead-acid batteries require routine
watering as described below. Check the battery
electrolyte level weekly.
The electrolyte level should be slightly above the
battery plates as shown before charging (Figure 40).
Add distilled water if low. DO NOT OVERFILL. The
electrolyte will expand and may overflow when
charging. After charging, distilled water can be added
up to about 3 mm (0.12 in) below the sight tubes.

Before Charging
NOTE: Make sure the battery caps are in place while
charging. There may be a sulfur smell after charging
batteries. This is normal.
CHECKING CONNECTIONS / CLEANING
After every 200 hours of use, check for loose battery
connections and clean the surface of the batteries,
including terminals and cable clamps to prevent battery
corrosion. Use a scrub brush with a strong mixture of
baking soda and water (Figure 41). Do not remove
battery caps when cleaning batteries.
