mixing batteries

[YourNameHere 10+ year member]

ok so the size and location of my stock battery makes it hard to find a kinetik or optima ect ect... that will fit. tried fitting an optima in there when i first got the car but my cables were too short to reach the posts, so my question is would it be a bad idea to add a second battery (kinetik) in the back with my regulay battery? one being wet cell and one being dry???

You should be fine. What's the make and model of the car your working with, maybe someone else in here has done something with the same vehicle.

Well i drive a 98 sable and i have stock battery upfront some no name shit and 2 spv70's in the rear and i havent had any problems at all with it. All the batteries maintain very good voltage even while hitting the low notes(13.4v or so and no big three yet).

Hope this might answer your question.

I know, I did that with a Kinetik 2000, but it was too big so I had to go with the Kinetik 1800 under the hood. Lucky for me I bought the battery from a friend who owned one of each, so I could try it out with each one. If you're putting in a battery and using the stock location I can't see why you'd have an issue with the wires being too short. Do you have top mount terminals or side mount?

top mount

i think i will just keep the stock one and buy sumpin for the rear, but will i need some type of isolater?

 

[king ranch 5,000+ posts]

just extend the wires make them longer, no isolator unless u play it with the car off alot, otherwise its a waste of money

 

[YourNameHere 10+ year member]

extending the wires isnt an option i have

You can keep the front batt and just add a good one to the rear. Since it'll be going in the trunk you can get the biggest one you can afford, a Kinetik 2400 is a great choice. So would something from Odyssey/Stinger.
