Performance and Regeneration of Lead-acid Batteries and the Use of Battery Activator for Electric Wheel Chairs

抄録

The driving and charge-discharge tests were carried out on the used lead-acid batteries for electric wheel chair. When the used batteries were repeatedly subjected to driving test on road after full charge, the electricity delivered from the battery during driving was gradually decreased. This battery was discharged at 90A after full charge, the driving time was increased because of the improvement of sulfation by the discharge at higher current. The batteries with/without activator were tested to confirm the effect of activators under the similar charge-discharge conditions as that in driving on road.
