Overview

Tractor batteries are an open cell type. This type of battery allows you to add distilled water to each individual cell. In order to add water to the battery, you may have to remove the battery from the tractor to gain access. Once the individual cells are topped off with water, you can then connect the storage device to a regular battery charger. The overall charging time may exceed 12 hours.

Step 1

Wear safety glasses whenever servicing any type of battery. Small particles can become airborne during the service operation.

Step 2

Use either a 7/16-inch or half-inch end wrench to remove the negative (-) battery clamp from the battery terminal post, depending on your battery clamp. Turn the wrench in a counter-clockwise direction. Next, loosen and remove the positive (+) clamp from the battery.

Step 3

Remove the battery from the tractor. Place the battery on a firm surface in a well-ventilated area.

Step 4

Unscrew and remove the top battery caps from each individual cell. A 12-volt battery will have six caps, and 6-volt batteries will have three caps. Each cell contains a separate charging plate that can hold a charge of 2 volts. The plates are internally connected to give the final battery voltage.

Step 5

Add distilled water to each separate cell. The water level should be to the bottom plastic ring in each cell.

Step 6

Clean the terminal battery posts with the steel brush. The posts should have a shiny metallic color.

Step 7

Connect the battery charger to the battery in the following order. Attach the black clamp to the negative (-) terminal, then secure the red clamp from the battery charger to the positive (+) post on the battery.

Step 8

Observe the voltage selector switch on the face of the battery charger. Ensure the switch is in the correct voltage position. A 12-volt battery must be charged by 12 volts. A 6-volt battery must have the voltage switch set to the 6-volt charging state. Plug the charger into the wall outlet.

Step 9

Remove the battery from the charger once the meter on the face of the battery charger reaches "0 amperes." The battery is now fully charged. Place the battery back in the tractor in the reverse order of what was described in step 2.

Tips and Warnings

  • Charge batteries in a well-ventilated area. All batteries emit explosive gases when being charged.
