Battery change for Tige

[chpthril]

Duncan just brought this to my attention, looks like Tige is putting in Optima Blue Tops as the "house" battery in the EIDB system, hmmmmmmmm.

So they mix it with a standard wet cell on the starting side?

That's the way it reads to me I don't like this idea because of the diff in charge rates between Wet and gel, couple that with a .5-.7v drop across the Iso, and you have a low starting battery.

Wow. Shoutout by chpthril

For the record, I said "gosh, look at the pretty blue color in this pic" (paraphrased). chpthril drew his own (spot on) conclusions.

Interesting....

I have never liked the diode voltage drop in the EIDB system... or any other system for that matter....

.7 volts is 5% of the charge voltage...

That is how it reads. I think the wet cell will recharge quicker, won't it? So that would mean that the system would recharge the starting battery first, and then top off the wet cell, so I think it would be OK.

I still think it makes the most sense not to mix and match. I guess we will know in a year or so how well that works when guys start complaining they got stranded in their Tige.

So would the ideal solution be different batteries and/or isolator, perko, or isolator/perko?

And what is the EIDB factory solution: isolator, perko, or isolator/perko?

The best set up is like batteries, batteries of the same type i.e: lead-acid wet-cel, AGM, Gel-Cel, etc.

Unless Tige has made further changes, the EIDB consisted of a starting battery, house battery, a Diode type iso, and an ON/OFF battery switch.

It sounds like they could use one red or yellow top and a blue top.

Would that do it?

That would, and they may be doing that on the 09..........Anyone with an 09 w/EIDB want to pull your battery covers and tell us what ya got!!!

I like my interstate HD rv/Marine batteries that came with the boat. Over 4 years, neer charged till this year and still going strong

[chpthril]

^^^ I'm with you Jim, you just cant beat a good quality wet-cell, a lot of bang for the buck. If you are going to the wild side with a system, or want to crank the tunes for 8 hours a day on Sat and Sun while at the sandbar, then it's worth looking into something like Kinetics or 6v's.

I'll try to remember this weekend to look and report.

I can tell you that my boat (an '07) came with an Interstate battery and then something else for starting it. They are 2 different amperage batteries, I think one is a 750 cca and the other is like a 950 or something. I understand that they are both wet cell batteries so they most likely charge at the same rate.

[dingleberry]

OK - I finally got around to taking a look at my batteries. I got the factory EIDB system (but, I did not get the ballast or Tower or Power systems - maybe that made a difference). Mine came with Interstate cranking and deep cycle batteries. See pics below. Hmmm....should I be upset or relieved that it isn't Optima? Or are they about equal?





Also - the isolator is a Blue Sea. Any reason for concern?
