Could be your not following the manufacturer's poorly written instructions. All Lithium ion batteries must be charged by a special sequence of events or program in order to prevent damage to the battery by overcharging.
The BionX handle bar console should be switched off both before connecting the charger, and while charging.
Before connecting the charger to the battery, make sure the charger's on-off power switch is in the "off" position. Connect the charger to the battery and then turn the charger's on-off switch to the 'on' position. This sequence enables the charger to initialize the charging program.
If you plug the charger in with the power switch in the 'on' position, the charger, which is microprocessor based, will incorrectly sense the batteries current charge state.
