Optima Red Top
Well you guys have frightened me into swapping the battery, which I only fitted in November, for an Optima Red Top.
Do you fit the dinky sponge jacket or allow it to show its six pack?
What’s the jacket for anyway?

Mine came with that dinky sponge jacket. When I changed my original 6yr old Delco, I did re-use it on the DieHard replacement. It's listed as an Insulator,Bat in the parts description. It's purpose, I don't know, but thought maybe it was there to help protect the other parts from spillage/leakage.

Probably to help soak up the leaking acid on the Delco

Battery Insulator
From what I've read, the black battery jacket is supposed to keep the heat down on the battery (it get's hot under a Corvrtte hood). It is an insulator, not a battery acid collector although it's probably soaked if you have a leaking battery. The original one from DELCO will fit a 78 profile traditional battery, probabaly won't work on a '6 Pack' OPTIMA since the insulator is shaped to be used for a square sided battery.
