12.1 Battery Cleaning, continued
12.1.3 Heavy Corrosion Cleaning
If the routine cleaning of bolted connections has been neglected, heavy post
corrosion may occur. The performance of the battery under load could be adversely
affected and this condition could present a safety hazard.
To perform the heavy corrosion cleaning:
Unbolt and remove connectors.
Apply a solution of baking soda and water to the cell posts and connectors to
neutralize the corrosion (as shown in Section 12.1.2, Procedure 1). Do not allow
solution to enter cells.
Clean the contact surfaces by rubbing the surface of the post or terminal and
lead plated contact surfaces with a stiff-bristle nonmetallic brush or pad. Exercise
care so you do not remove the lead plating on the connectors, terminal plates or
lugs, exposing copper.
Recoat the contact surfaces with a thin application of the ARONIX grease,
applied with a small paintbrush. Remove any excess grease from the cover.
Reinstall and tighten connections to appropriate torque value. See Section 7.5.3.
12.1.4 Cleaning Flame Arrestors
When cells are overfi lled with electrolyte (above the high level line) or are excessively
overcharged, the diffuser material of the fl ame arrestor may become partially clogged
from electrolyte spray. Replace all fl ame arrestors having clogged pores or clean the
arrestors as follows:
Immerse the fl ame arrestor several times in a plastic bucket fi lled with distilled
water. After each immersion, eject the water by vigorous shaking or with an air
blast. Following the immersion of 15 fl ame arrestors, dump and refi ll the bucket
with clean distilled water.
Do not use any cleaning or neutralizing agents in the cleaning water, since any
dry residue may clog the pores of the diffuser materials.
12.1.5 Replacing or Isolating a Cell
To replace or isolate a cell for maintenance:
Unbolt and remove connectors.
Remove and replace cell or isolate the required cell.
Reinstall and torque connections according to Section 7.5.3.
