Hello all, I got new batteries on my boat and went with 2 6V's I'd like to keep them in better condition than I did my old and read about equalizing... one site said to do it as often as 6 times a year. I have a sentry 1210 charger on a 99 361 and the manual doesnt mention this function.... Does everyone here equalize and if the charger doesnt do it automatically how do you ? thanks Gaute
