Battery Life

   Good thread.
We've got a 385. And we're having battery issues at the moment.
We've found that if on shore power for long the batteries get very hot. It's like they are getting overcharged although over battery monitor doesn't really show this.

I believe the shore power charger on the 385 is a 'Quick' charger brand. I can't find ANY details about this anywhere.

We have the standard cruising batteries. 2 x 165amp gel's I believe. No idea what's going on. It's almost as if the charger sometimes gets it right and then sometimes doesn't.

I don't like red hot batteries though.

	I had this happen to me twice on two different boats. Both times it was the charger. What type do you have?

	It's a 'Quick' make. But I can't find much more info than that. Very weird. Sometimes it takes ages when I reconnect to shore power for the charger to turn off. I've also noticed that if the batteries get hot (which they sometimes do when back on shore power after a while off) I need to disconnect from shore, leave it a while, and then reconnect. Then the charger seems to work and turn off when it should. It has been very hot here also as well, maybe that hasn't helped. I've been off shore power for a few hours now and they are still very hot to the touch.

	The old charger cooked my batteries (2 yrs old). I replaced the charger with a pronautic charger (UK) two years ago and so far all is good. http://promariner.com/products/dry-mount-marine-battery-chargers/pronauticp-series/
