It's a Zivan NG3 charger, so the last (3rd) stage of charging is "fry the batteries". 2A at whatever voltage it takes. That's why I have RR MKII"s installed. It seems that the NG3 never made it to the 3rd stage. I don't remember if 188 (or so) volts is the correct value for the constant voltage state (2nd) or not. >You say this has happened a few times lately, so it may continue or even >increase. Do you suspect it to be a malfunction of the charger? Could be. Don't know. It has only happened on the "warmer" days when it got up to 70 or so outside. >If the batteries are the source of the problem perhaps the list can learn >from your experience.

Next time I see it happening, I'll try to check the battery voltages. So far I've caught it twice, both at times when I couldn't take the time for a good diagnosis. -- John G.
