We have been investigating the prolongation of the life-time of lead-acid batteries in the view point of environmental aspects and material resources. Since 1997, we have been working on the activators for lead-acid batteries. We developed various activators using composite organic polymers with solid powder, organic polymers, etc. The effects of prolongation of life-time have been compared between our activators and the other commercially available additives, using actual 6 V batteries for motor cycles. The change in the internal resistance of batteries has been measured during discharge-charge cycles to clarify the deteriorating mechanism. Organic polymer P is useful for prolongation of the life-times of lead-acid batteries if it is used with a suitable amount. The solution of electrolyzed carbon particles with 2.00 ms/cm is also effective for enhancement of the battery performance, and more effective if it is used together with a small amount of organic polymer. The internal resistance of the battery becomes a good index of deterioration of the battery.
