Losing Charge

• According to many wheelchair users if wheelchair batteries are charged infrequently or lef for an extended time without being charged they will be permanently damaged and eventually get to the point where they can no longer hold any charge. The result will be "unreliable power chair operation and limited battery life," according to the Jazzy owner's manual.
  
  

Preventing Damage

• The manual for the Jazzy Wheelchair 610 Series suggests owners charge their wheelchair batteries 14 to 18 hours at a time. Jazzy wheelchairs are designed to last 24 hours on a single charge, according to Jazzy Wheelchair Features. Each Jazzy wheelchair comes with battery chargers. Owner's manuals as well as technicians at medical equipment dealers should explain how to connect batteries to chargers.
  
  

Further Warnings

• Jazzy wheelchairs typically use two batteries. For wheelchairs to function properly both must be charged. Specifics for charging will be explained in owner's manuals. Explosive gases may be generated while charging Jazzy batteries so owners should keep wheelchairs and batteries away from any source of ignition and provide ventilation when charging batteries. Owners should avoid charging or storing batteries in extreme tempatures so they do not freeze or overheat. Additional warnings are included in all Jazzy owner's manuals.
