Im trying to researcha dual batteries system in my Disco. Any ideas?

 

On a D1, you can add a second battery over by the air filter with just a little work, then tie the batteries together or throw a switch between them.
Why are you looking for duals and what battery are you looking at?

 

I have an after market audio system with 2 powerful amps. I audio shop recomended to add a second battery. I trying the do it the less $$$$ way but, still get it done so it work like it should. Later I want to add lights and a winch!

 

If you will also be going for a winch, go to Deep Cycle batteries now, like Yellow Tops.

 

Yellow top's are trash. Try a DieHard Marine Battery, Platinum PM-1 - Group Size 31M from sears. Do it right the first time.

 

Well that trash works well for many of us. Have you ever tried one or are you into hear say?

 

the best thing to do to keep your audio system from draining your batteries and putting a strain on your alternator is to have a capacitor installed... i had a 1.5 farad capacitor and a 2000 what amp with two tens in my old car and when i turned it up and the bass hit the capacitor kept my lights from dimming like they would have without it...

So, Your saying that Yellow tops are better than oddessy's? Cause, that's whatthat searsbattery is. Just stating the facts...

 

The facts are there are a couple of different Odessey batteries, and the company that makes them also makes a battery for Sears, but I believe that the Sears version is of lesser quality the the original Odessey.
As for the comparison between the Yellow Top and the Sears battery, all I can say is mine duals work well and were way more cost effective then 2 Odessey's.

 

does adding a second battery put a great deal of strain on the alternator?

if you were to put one in place, would you just connect it to the existing battery: pos to positve, neg to neg. ?
