Is the cover over the battery on a 91 LS 400 really needed? Mine is currently missing. Is it more of a cosmetic part or does it serve a purpose?

 

It used to serve a purpose with old batteries, which were prone to exploding, and needed to be cooled down. With modern batteries, its not needed.

 

Never thought of that Och but it makes sense.
It does offer some strain relief for the cables.

Nevertheless I discarded it and the oem terminals when I replaced my last battery. Damn, batterys have gotten pricey!!

 

Get an optima you'll NEVER have a problem!

 

yea they sure did get expensive, the optimas are like 180bucks at autozone or pepboys...

 

i prefer the Diehard platinum from sears (the sealed gell/spiral cell competitor to optima) but they were out of stock when i bought mine

 

Better pick it up then. Paid $225 for my yellow top last year.

 

i thought i overpaid when i spent $130 for my red top for my Cressida back in 2003.

 

Good call on that battery, just picked one of those up off of the recommendation of your post yesterday cause I just redid my alternator a few days ago and wanted a new batt too, I am loving the quality of that battery, very nice.
