TP-6195 1/04 15Section 3 Scheduled Maintenance
Refer to this section for general battery information and
maintenance. All generator set models use a negative
ground with a12-volt engine electrical system. Consult
the generator set nameplate for the engine electrical
system voltage. Consult the generator spec sheet for
battery capacity recommendations for replacement
purposes. Wiring diagrams provide battery connection
information. See Figure 3-7 for typical battery
connections.
Check the electrolyte level and specific gravity of
batteries with filler caps. Maintenance-free batteries do
not require electrolyte level checking or specific gravity
testing.
Clean the battery and cables and tighten battery
terminals using the service schedule recommendations.
Clean the battery by wiping it with a damp cloth. Clean
both battery terminals with baking soda. Keep the
electrical connections dry and tight.

3.8.1 Cleaning the Battery
To prevent dirt and grime buildup, occasionally wipe the
battery with a damp cloth.
To prevent corrosion, maintain tight, dry electrical
connections at the battery terminals. To remove
corrosion from battery terminals, disconnect the cables
from the battery and scrub the terminals with a wire
brush. Clean the battery and cables with a solution of
baking soda and water. Do not allow the cleaning
solution to enter the battery’s cells. After cleaning, flush
the battery and cables with clean water and wipe them
with a dry, lint-free cloth.
After reconnecting the battery cables, coat the battery
terminals with petroleum jelly, silicone grease, or other
nonconductive grease.
3.8.2 Checking Battery Electrolyte
Level
Check the battery electrolyte level before each startup.
Remove the filler caps and verify that the electrolyte
level reaches the bottoms of the filler holes; see
Figure 3-8. Refill as necessary with distilled water or
clean tap water. Do not add electrolyte. Install and
tighten filler caps. After adding water to the battery in
freezing temperatures, run the generator set
20--30 minutes to mix the added water and the battery
electrolyte. Mixing the water and the electrolyte
prevents the added water from freezing and damaging
the battery.
