[2021STK]

With the higher end "S" brand charger I've noticed a voltage creep going beyond the normal 13.2-14V up to and over 16V at times with 2 different chargers. If I catch it, unplug the charger and plug it back in it'll stay at less than 14V from then on. I mentioned this situation to a couple of other racers and they found they had same creeping problem. This also happened on lead acid batteries that I was charging over night and the acid was boiling by morning. Now I won't leave a charger running, only a battery tender. Please stay aware!
