REJUVENATION OF DEAD LEAD ACID BATTERY WITH OLD LAPTOP CHARGER

Recharge batteries that refuse to take a charge. The charger is an old laptop charger i had laying around for years. It is a 24 volt 1.73 amp charger. This process did not happen fast. But has proven to be very reliable and hassle free. I have been able to rescue and fully bring back 75% of all batteries using this process. The only way to de-sulfate a completely dead battery i have found is to overcharge it....... safely. This takes time. 24 volts x 1.73 amps is only 41.52 watts and the charger will cycle on and off as it senses the battery is resistance to a charge. It interprets this as an open circuit and shuts off the charging momentarily Then the cycle starts again. It is slow to begin with, it picks up speed near the end of the process. When the battery can maintain a 14 volt charge after settling out, the process has been completed. This also works with 6 volt batteries hooked in series.
