Things You'll Need:
- Safety glasses
- Rubber gloves
- Paper towels
- Slotted screwdriver (optional)
- Distilled water
-
Step 1
Place the safety glasses and rubber gloves on your body to protect yourself from any possibility of spillage from the acid water mixture. Remove all electrical power from the charging system to the battery. In most cases this is simply pulling the plug from the AC charger that feeds the battery.
-
Step 2
Clean the top of the battery with a paper towel. Discard the towel immediately as it might contain dried acid.
-
Step 3
Remove the caps of the battery. Various unsealed batteries may have different caps. Individual screw on caps will cover each separate battery cell, which will be six in total for one battery. Unscrew the separate screws caps and set to the side. Use the slotted screwdriver to pry off the caps if they are part of an assembly. Most typically these pry off caps will cover three cells. There will be two caps for one battery.
-
Step 4
Observe inside the openings of the battery. There will be a plastic ring that extends down inside each cell. Check the fluid level of each cell. The fluid height must be kept to just below the level of the interior ring.
-
Step 5
Add just enough distilled water to raise the fluid level to the height of the lower end of the interior plastic ring. Replace the caps on the battery. Thoroughly wipe the top of the battery dry with the paper towels. Reenergize the battery charging system.
