- Yes indeed ! In fact, the digital meters that I'm fond of recommending will generally not display a stable reading at all when measuring the open-circuit voltage from a typical battery charger. Rand

- Sounds like we agree that if the voltage stays at 14.6 or so, no damage will be done to the battery. If the battery's are being damaged, then the voltage must be rising to above 14.6 V for some reaso
