Battery Service - Toro Reelmaster 6500-D Service Manual

Battery Service

The battery is the heart of the electrical system. With
regular and proper service, battery life can be extend.
Additionally, battery and electrical component failure
can be prevented.
When working with batteries, use extreme cau-
tion to avoid slashing or spilling electrolyte.
Electrolyte can destroy clothing and burn skin or
eyes. Always wear safety goggles and a face
shield when working with batteries.

Removal
IMPORTANT: Be careful not to damage terminal
posts or cable connectors when removing the bat-
tery cables.
1. Open engine hood. Loosen battery retainer securing
the battery to the frame.
2. Loosen nut on ground cable (-) post first and remove
cable from battery. This should prevent short circuiting
the battery, other components, or the operators hands.
3. Loosen nut on positive (+) cable post and remove
cable from battery.
4. Make sure battery vent caps are on tightly.
5. Remove battery from the battery compartment to a
service area to allow better access for service.

CAUTION
Inspection, Maintenance, and Testing
1. Perform following inspections and maintenance:
A. Check for cracks. Replace battery if cracked or
leaking.
B. Check battery terminal posts for corrosion. Use
wire brush to clean corrosion from posts.
IMPORTANT: Before cleaning the battery, tape or
block vent holes to the filler caps and make sure the
caps are on tightly.
C. Check for signs of wetness or leakage on the top
of the battery which might indicate a loose or missing
filler cap, overcharging, loose terminal post, or over-
filling. Also, check battery case for dirt and oil. Clean
the battery with a solution of baking soda and water,
then rinse it with clean water.
D. Check that the cover seal is not broken away. Re-
place the battery if the seal is broken or leaking.
E. Check the electrolyte level in each cell. If the level
is below the tops of the plates in any cell, fill all cells
with distilled water between the minimum and maxi-
mum fill lines. Charge at 15 to 25 amps for 15 min-
utes to allow sufficient mixing of the electrolyte.
2. Conduct a hydrometer test of the battery electrolyte.
IMPORTANT: Make sure the area around the cells is
clean before opening the battery caps.
A. Measure the specific gravity of each cell with a
hydrometer. Draw electrolyte in and out of the
hydrometer barrel prior to taking a reading to
warm-up the hydrometer. At the same time take the
temperature of the cell.
B. Temperature correct each cell reading. For each
10_F (5.5_C) above 80_F (26.7_C) add 0.004 to the
specific gravity reading. For each 10_F (5.5_C) be-
low 80_F (26.7_C) subtract 0.004 from the specific
gravity reading.
Example: Cell Temperature
Cell Gravity
100_F minus 80_F equals 20_F
(37.7_C minus 26.7_C equals 11.0_C)
20_F multiply by 0.004/10_F equals 0.008
