Comparative evaluation of chargers for wheelchair gel cell batteries.

This study was undertaken as part of our ongoing work to upgrade wheelchair quality. Laboratory tests were conducted to determine which battery chargers would ensure that the user's batteries are fully charged each night and also ensure that the battery lifetime was not diminished. Five commercial chargers were tested on a standardised pair of gel cell batteries of a type commonly used to power wheelchairs. Results of this study indicate a clear preference between chargers. As a result, we have changed the chargers we purchase. We anticipate that our clients will now experience longer life from their wheelchair gel cell batteries.
