Batteries

WARNING
The voltage in the battery pack is sufficient to cause death by electrocution. With the exception of battery inspections and refilling the water in flooded type batteries, never attempt to perform service on the electric drive system, including the battery pack, unless you are properly trained to work on electrical systems. Your authorized GEM dealer can provide battery-related service.
WARNING
Battery posts, terminals and related components contain lead and lead compounds, chemicals known to cause cancer and reproductive harm. Always wash your hands after touching or handling the batteries.
WARNING
Charging a damaged battery can result in serious injury. Never attempt to charge a frozen or bulging battery. Discard the battery appropriately and install a new battery.
WARNING
Battery electrolyte is poisonous. It contains sulfuric acid. Serious burns can result from contact with skin, eyes or clothing.
Antidote:
External: Flush with water.
Internal: Drink large quantities of water or milk. Follow with milk of magnesia, beaten egg, or vegetable oil. Call physician immediately.
Eyes: Flush with water for 15 minutes and get prompt medical attention.
Batteries produce explosive gases. Keep sparks, flame, cigarettes, etc. away. Ventilate when charging or using in an enclosed space. Always shield eyes when working near batteries. KEEP OUT OF REACH OF CHILDREN.

Traction Battery Configurations

NOTICE
Before accessing the batteries, make sure any wire or metal items remain clear of the battery compartment to avoid causing a short circuit to the electrical system.
Several battery pack configurations exist for GEM vehicles.
  • Four 12-volt lead acid batteries
  • Eight 6-volt lead acid batteries
  • Single module lithium ion battery pack
  • Dual module lithium ion battery pack

Traction Battery Locations

To access the battery pack, remove any rear accessory back installed on the vehicle. See Rear Accessory Backs (Option). Release the battery pack access cover fasteners and remove the cover.

Battery Inspections/Maintenance

WARNING
Do not work in or near the battery compartment or on any other electrical component of the vehicle while charging the batteries. Before servicing the vehicle’s electrical system, always unplug the service disconnect first, then disconnect any electrical accessory connections, then disconnect the negative cable from the 12-volt battery, then disconnect the negative terminal from the main battery pack. This will disable the vehicle by disconnecting the battery pack from the motor. It does not disable the battery pack. HIGH VOLTAGE will be present at the battery terminals. HIGH BATTERY VOLTAGE IS ALWAYS PRESENT. DO NOT TOUCH THE BATTERY TERMINALS.

Check Battery Connections

WARNING
Improper handling of high voltage wiring, batteries or control systems could result in serious injury or death by electric shock. Only qualified GEM technicians should repair or access high voltage wiring, battery packs and associated systems.
Inspect and clean battery terminal connections monthly. Carefully remove corrosion with a stiff wire brush. Coat battery terminals with dielectric grease or petroleum jelly. Using an insulated wrench, torque bolts to 8 lb-ft (10.8 Nm).

Check Battery Cables and Wiring

Check the battery compartment for any signs of worn insulation, frayed cables or damaged cable ends. If found, see your authorized GEM dealer or other qualified service person for service before operating.
WARNING
If battery cable ends are damaged or corroded, they should be replaced or cleaned as necessary. Failure to do so may cause them to overheat during operation, possibly leading to fire, which may result in serious injury or death.

Check Battery Hold-Down Bars

Battery hold-down bars should be snug to keep batteries from moving while the vehicle is in motion, but not so tight as to crack or buckle the battery case. Torque fasteners to 9.5 lb-ft (13 Nm).

Battery Replacement

WARNING
Handling batteries and electrical components improperly can result in serious injury or death. Do not attempt to remove batteries or battery cables. Battery posts are identified on the battery case as positive (+) and negative (-). Your authorized GEM dealer can provide battery-related service.
With proper care and maintenance, as outlined in this owner’s manual, battery life can be maximized, but the battery will eventually reach the end of its useful life. When battery replacement is necessary, your authorized GEM dealer can provide this service.
NOTICE
Always install batteries of the exact type and make originally supplied with the vehicle to prevent damage to the vehicle’s electrical system.

Battery Care During Storage

When the vehicle will not be used for a period of 10 days or longer, check battery water levels (flooded type batteries) and perform one of the battery storage procedures listed in the chart below.
NOTICE
If ambient temperatures could drop below freezing during the storage of a vehicle equipped with lithium-ion batteries, refer to the cold battery performance information beginning on BRAMMO® Lithium-Ion Cold Battery Performance.

Battery Storage Options

Storage Period

Charging Procedure

Less than 10 days

Fully charge the batteries, park the vehicle and turn the ignition key off. The battery will lose some of its charge during this period.

10 days to 24 weeks

Leave the charger connected. See On-Board Charger.

Indefinitely or Unknown

Disconnect the charger and arrange for monthly charging.

Auxiliary Battery Storage

Vehicles equipped with EPS / Lithium-Ion batteries are equipped with an auxiliary battery. During storage, this battery must be trickle charged. If the vehicle does not operate when removing from storage, be sure to check the auxiliary battery voltage first.

Flooded Battery Fluid Check

On flooded batteries, check the fluid level often. Add only distilled water. Tap water contains minerals that are harmful to a battery.
Accessory watering systems are available for 12-volt and 6-volt flooded batteries. See your authorized GEM dealer for more information.
NOTICE
Never charge batteries if plates are exposed above the water level.
Unless the plates are exposed before charging, distilled water should be added to a battery after charging. If the plates are exposed, add just enough water to cover the plates. Fully charge the batteries, then recheck the fluid level.
Maintain the fluid level between the battery plates and the bottom of the fill well. Do not overfill.
caution
The fluid in an overfilled battery may boil over and cause electrolyte to spill.

Image
Inspect the fluid level of each battery.
  1. Remove one of the fill well caps .
  2. View the fluid level.
  3. Maintain the fluid level between the battery plates and the bottom of the fill well. Add distilled water as needed. Do not overfill. Reinstall the fill well cap securely.
TIP
The battery plates should be visible when looking into the fill well. Use a flashlight if necessary.
TIP
If the level is below the plates, add just enough distilled water to cover the plates. Fully charge the batteries, then recheck the fluid level.

Battery Cleaning

  1. Remove corrosion with a stiff wire brush.
  2. Wash the terminals and tops of the batteries with a solution of one tablespoon baking soda and one cup water. Rinse well with tap water and dry off with clean shop towels.
  3. Make sure battery terminals are tight. Use an insulated wrench to tighten as needed.
  4. Allow battery terminals to dry, then coat the terminals with dielectric grease or petroleum jelly, or spray them with battery anti-corrosion spray.
NOTICE
Do not allow cleaning solution or tap water to enter the batteries. Before cleaning, make sure all battery fill well caps are installed securely.

Flooded Battery Disposal

Lead-acid batteries can be recycled. Return to a local location that accepts used batteries. For neutralized spills, place residue in acid- resistant containers with absorbent material, sand or earth and dispose of in accordance with local, state and federal regulations for acid and lead compounds. Contact local and/or state environmental officials regarding disposal information. You can also contact GEM Customer Service for information.
