Safety
WARNING
Misused or abused lithium-ion batteries can get hot, explode or ignite, or potentially release gas, smoke or liquid. Always follow battery safety precautions. Misuse or abuse of lithium-ion batteries could result in death or serious injury. (07729b)
Safety Precautions
Handling
  • Do not use battery if it gives off an odor, generates heat, releases gas, smoke or liquid, becomes discolored, or deformed or appears abnormal in any way. If the battery is in use or being recharged, remove it from the motorcycle or charger immediately and discontinue use. Wear a protective face shield, rubberized gloves, respiratory protection and protective clothing when handling a damaged battery to prevent exposure to internal battery contents.
  • Never attempt to open or disassemble a battery. If accidental contact with internal battery contents occurs, wash the affected skin area and contact a doctor for further medical assistance.
  • Do not pierce the battery case with a nail or other sharp objects, do not break it open, do not step on it.
  • Do not place the battery in a microwave oven or pressurized container.
  • Do not immerse the battery in water.
  • Do not strike, throw or subject the battery to severe physical shock.
  • Do not press on indicator button longer than a few seconds.
  • Keep out of reach of children and pets.
Installation
  • Do not short-circuit the battery by connecting wire or other metal objects to the positive (+) and negative (-) terminals.
  • Do not reverse the positive (+) or negative (-) terminals.
  • Do not install the battery in a vehicle with a modified Original Equipment Manufacturer (OEM) charging system, alarm system, drive train, etc.
  • Do not fit extra Audio, Anti-theft lock and other electronic device to your vehicle by yourself.
  • Do not directly solder to the battery terminals.
  • Do not use the battery in combination with other batteries (for example, using more than one battery in parallel or in series).
  • Always affix battery cables to battery terminals securely with original screws and nuts supplied. The battery and/or vehicle may be damaged by sparks caused by loose connections.
Charging
  • Do not recharge battery if voltage is below 8 V to prevent hazardous situations. Charging a deep discharged battery can cause release of smoke, gas and liquids.
  • To prevent damage to the battery, the charging voltage should NEVER be higher than 15 V.
  • Do not overcharge: In case of overcharging, a degassing event with smoke generation might occur.
  • Do not connect the battery directly to a wall outlet (Alternating Current (AC) outlet).
  • Only charge or discharge the battery in a well-ventilated area.
  • Always use a Lithium-Ion (Li-ion) battery specific battery charger to charge the Li-ion battery, verify charging voltage is between 14–15 V.
  • If motorcycle is not equipped with a battery tender connector, then remove battery from motorcycle prior to charging. See owner's manual.
Storage
  • Avoid contact with any corrosive substance.
  • Do not store the battery near sources of fire, heat, water or rain.
In the Event of Contact with Internal Battery Contents
WARNING
Contact with internal battery contents can have serious health effects. Wear protective face shield, rubberized gloves, respiratory protection, and protective clothing when handling damaged batteries. Failure to wear proper protective gear while handling a damaged battery could result in death or serious injury.
See Safety Data Sheet (SDS) for more details available at sds.harley-davidson.com (07728b)

Battery Charging
WARNING
Gasses released during charging, could cause death or serious injury. Charge battery in a well-ventilated area. Keep open flames, electrical sparks and smoking materials away from battery at all times. KEEP BATTERIES AWAY FROM CHILDREN. (07805a)
1. Verify that the battery charger has a mode for lithium-ion charging.
NOTE
If it is necessary to charge the battery, a charger with a lithium-ion charging mode is required to fully charge the battery. Harley-Davidson recommends the use of a Harley-Davidson battery charger with lithium-ion charging mode.
2. Inspect battery charger, verify that the charger leads are not damaged, frayed or loose.
3. Never charge a battery without first reviewing the instructions for the charger being used.
4. Perform a battery charge test. On the battery capacity indicator press test button to view a general indication of battery charge status. Verify battery state of charge with a DVOM to determine if the battery needs charging.
a. Battery is fully charged at 13.4 V.
b. Only charge if reading is equal to or greater than 8 V.
c. If battery is less than 8 V: If battery is within the applicable warranty period, return to Harley-Davidson dealer.
5. If necessary, see applicable owner's manual and remove the battery from the motorcycle. Place the battery on a level surface.
NOTE
If motorcycle is not equipped with a battery tender connector, then remove battery from motorcycle before charging. See owner's manual.
6. Inspect battery for damage. Replace battery if visibly damaged or frozen.
WARNING
Unplug or turn OFF battery charger before connecting charger cables to battery. Connecting cables with charger ON can cause a spark and battery explosion, which could result in death or serious injury. (00066a)

  3. Mark the charging date on the battery.
Battery Storage
If the motorcycle will not be operated for several months, such as during the winter season, remove the battery from the motorcycle and charge fully. See BATTERY CHARGING.
To reduce self-discharge rate, store battery in a cool (not freezing), dry place.
  • Always store in a clean, dry, and ventilated environment of -20–40 °C (-4–104 °F).
  • Check the battery State of Charge (SOC) every 6 months (180 days). Test battery V and charge battery if needed. Table 2
NOTE
Harley-Davidson Constant Monitoring Battery Chargers in Lithium-Ion mode may be used to maintain battery charge for extended periods of time without risk of overcharging.
When returning a battery to service after storage, refer to the instructions under BATTERY CHARGING.
Transportation
  • Do not strike, throw, or subject battery to severe physical shock.
  • Do not transport batteries together with flammable, explosive or sharp objects.
  • Battery should be packed with insulation and shockproof material to avoid damage from sudden jolts and collisions.
  • Battery should be handled with care when loading and unloading during transport.
