My question is,
Ive been wanting to do an extra battery in my truck since i put the LS1 Fans on.
Can someone give me a PN for the AUX Battery Tray that goes on the Passenger side of the engine compartment??
and how much do they usually cost??


Supercharged engine from the General!?!?
Why did it get locked??

but anyway, i thought that the 6.2L was goin in the denalis and esclades and maybe the Tahoes??
but since its FI now, who knows what they goin to do?

 

Part number is 15705102. List is around $27. Paid about $17 through gm parts direct, but ordered a bunch off stuff to justify shipping charges. Battery holddown clamp is part number 356668. Forgot the part number for the bolt.

 

Just invest in a good optima battery and that should do it. I know that laptop takes alot of power but come on.

 

Keep in mind that the extra battery will give you extra run-time with the engine off, but will NOT help provide more current when the engine is running. It will just load up the alternator even more.
