•  Batteries supply the power for your chair.They contain a finite amount of 

energy and have limits on how long they can store and supply energy.

• You can charge batteries only a certain number of times before they will

fail and no longer hold a charge.

•  For answers to questions about batteries, consult your supplier.

Your chair operates on two 12 volt batteries.

•  They should be Group 24 size with a minimum of 65 ampere hour rating and

of the deep cycle type.

•  When you buy a replacement, insist on a deep cycle type. Do not use a

car starter battery.

•  A battery requires “breaking-in” for the first 6 to 12 charges. It will not

accept a full charge for this period.

•  It is best to limit the length of your trips until you break the batteries in 

and you know the range of your chair.

•  Never allow a battery to completely discharge. If you operate your wheelchair 

until it has almost stopped, you will greatly reduce the life of your batteries.

•  Never let a battery sit in a discharged condition. Give unused or stored 

batteries a full charge once per month.

•  Always fully charge the batteries. Avoid “topping Off” with 

frequent charges.
