BATTERY

The STAMPEDE 900 has a sealed battery, which requires no maintenance except to keep it corrosion-free, and to test
for functionality.
The sealed battery is filled with electrolyte and sealed at the factory. Never pry the seal strip off, or add fluid to the bat-
tery.
Inspect the battery terminals at the intervals indicated in the SCHEDULED MAINTENANCE CHART on page 46.
Clean and tighten as needed.

Battery Cleaning

Use insulated wrenches to prevent direct contact of a wrench with the battery terminals.
Direct contact of a bare wrench with battery terminals can cause an explosion resulting
in severe injury or death
Always wear eye protection when charging the battery.
NOTICE: To decrease the risk of damage to electrical components surrounding the battery while cleaning, do
not use a pressure washer.
1.
Remove corrosion with a wire brush.
2.
Wash with a solution of:
• 1 tsp. (5 ml) baking soda
• 1 cup (236 ml) water
3.
Rinse with tap water and dry with shop towels.
4.
After the battery is clean and dry, coat with a commercially available battery terminal spray.

Battery Charging

Do not overcharge the battery. Overcharging the battery can cause overheating and pos-
sible explosion, resulting in severe injury or death.
NOTICE: Use a battery charger that is designed for charging sealed batteries.
Keep battery fully charged.
Heavy use of accessories can drain the battery and leave insufficient charge to start the vehicle.
The sealed battery is a 12 V starter battery that supplies power to the starter and accessories. A starter starts the
engine and an internal generator charges the battery while the engine is running. Due to heavy use of accessories,
the battery can become discharged even if the engine is running and the generator is operating.
It is important to keep the battery fully charged. Since the battery is sealed, a voltmeter or multimeter is required to
check voltage.
1.
Check the battery voltage with a voltmeter or multimeter.
• If the voltage measured is 12.8 V or higher, the battery is fully charged and requires no further action.
• If the voltage measured is less than 12.8 V, recharge the battery.
2.
Charge the battery with a charger designed for sealed batteries. Follow the instructions supplied with the manu-
facturer of the charger.

Battery Storage

NOTICE: A battery will self-discharge over time. The rate of discharge varies depending on ambient tempera-
ture, age and condition of the battery. Check the battery each month during storage and charge as
needed to maintain full charge.
A full charge will prevent the battery from freezing in winter conditions.
If the vehicle is going to be out of operation for three (3) months or longer, do the following:
1.
Remove the battery from the vehicle.
2.
Make sure the battery is fully charged.
3.
Store it out of the sun, in a cool, dry place.
4.
Check battery voltage each month during storage and recharge as needed to maintain a full charge.
