batterys under the seat?

[dalt1]

Thanks

[liljohn]

ok now i realy need some help i called my service guy at my malibu dealer and he say no gel batterys period. apparently there is a problem with the voltage from the alternator being to high and causing the batterys to only have half the life that they are supposed to. on top of that he tells me that over the course of time it will cause electrical problem cuz as the batterys lose there life the lose there amp rating (i.e. 600ccamp new two years from now will be more lik 300ccamps) dose any one understand what im saying or can anyone shed some light on he situation? i have a good relationship with my dealer so i tend to belive him. but....should i start a new thread with this queshtion as i know lots of you have gels in your boats..

That is the silliest thing I've ever heard... clearly someone is misinformed. All batteries degrade over time

[VinRLX]

Actually, don't the gel batteries require a different charger or method of charging than previous standard cranking or deep cycle batteries? I wonder if an amped-up alternator might cook the battery prematurely. Just thinking out loud, somebody on here must be knowledgeable about this.

I've got an Optima in my 66 chevelle, it's my boats old blue top 34m starting battery from 2004. I start the Chevy every 6-8 months with NO charge. My truck has had a yellow top for at least 3+ years and my boat has a deep cycle blue top D34m optima for starting since I swapped out the starting 34m one in 2004. The stereo uses the dry cell Stingers.

Never had an issue with the gel batteries. Edit , AGM batteries.

Yes, you're supposed to use a 2 amp or less charger on them. But I'm not sure that the 2 are an apples to apples comparison, it's not like gel batteries being used in high performance applications is a new thing. I've never heard of what that service guy said. My Optimas have been in the boat for 2 years & I haven't done a single thing to them until last weekend, & the cranking battery was still showing at near 100%. The accessory battery was low, but came up in a hurry when I put a trickle charger on it (charged at 2 amps & it took an afternoon to bring it up to 100%).

vin rlx said it better than i did. they degrade prematurly. i have a call in to optima to discuss this. ill keep you all posted. ps sorry my spelling and grammer suck.

[liljohn]

ok i just got off the phone with optima. heres the deal-optima are NOT gel batterie they are sealed acid batteries. as long as you dont exceed 15 volts from the alternator you are fine. but he also said to make sure and get ther right blue top apparently there are 2 models one is a deep cycle and the other is not. the one we should be using is d34m and not the 34m. sweet im buying them today and then im going to have a conversation of eduction with my service guy.

I got my deep cycle marine D34m at Costco, I think they had yellow also but it's been awhile since I've looked.

[Bill_AirJunky]

Nice installs guys. Thanks for adding to my to do list....

So batteries are not listed on Costco's website. Any idea of the price of the D34M?

Yeah, just keep telling yourself that. Bigger boat = more people and more stuff.

Ahhhh yes. The amount of liquid charge I consumed on that trip should have run that boat for weeks....

I can't remember which one I ordered, but I did call them & they took care of making sure that I had the right model.

Yup - me too.. 'cept, I just e-mailed them.

[Dave K]

Awesome, that is exactly what i would like to do, with my 99 sunsetter.

Q1. How do you determine if you need 2 batteries to run your stereo, or is that just a given?

Q2. What kind and model number are those batteries?
