First off, I know this topic is usually beat to death already but I want to ask a very specific question. I'm thinking of replacing both batteries on a 05, SR 220 Sundeck. I've read a ton about the difference between Lead/Acid, Gell and AGM. I'm also very handy and I know how to maintain lead/acid batteries. Obviously there a huge cost difference between these types.

I'm a mature operator with all my skiing days behind me, I'll be using this more as a cruiser to travel to destinations and stay in hotels.

For the guys/gals running lead acid batteries, do you get any oily film in your bilge from the batteries off gassing?


Thanks
 
No reason you would ever get an oily film from a battery. They don't have any oil in them. Even if they boiled over they should result in an oily film. Why do you think it is coming from the batteries?

No Zoomie - I run with 4 of them (lead/acid) and have no problem with any residue or film - but they're in a pretty large bilge area with plenty of air exchange. That (residue/film) may only be a problem if they were in a small confined area that lacks such air exchange... Good luck.
 
If I’m not cautious and accidentally overfill a cell, I’ll notice a film in that area some days later, after a charging cycle.
I wouldn’t call it oily, but it’s also not plain old distilled water.

I wonder if the acid dissolves something from what it spills onto? Maybe that is the film?

Well, ok, not oil but some kind of film that is not just water. I really don't know how to explain it, however, thanks to all the others that answered the question.

Are you an academy grad?

"Zoomie" is the nickname for US Air Force Academy cadets/graduates.

Just wondering if you might be one. I'm a 1987 grad.

Cheers. And welcome to CSR.

Oh I just re-read your message. I got that nick name from an ice fishing trip I went on years ago. I wanted to fish but it was really just a big drunk up. Bob Izumi is a TV fishing guy around here so they started calling me zoomie. It kinda stuck with my fishing and boating friends.
