Battery wrap needed?

My neighbor just bought a two year old Nissan. We noticed the "blanket" around the battery was rotted away on one side of the battery. Not chewed, but rotted. Touch the blanket and it crumbles where you touch it.

We wondered ... is a battery blanket wrap really needed? What's the purpose? The Nissan replacement part is $65.

Thanks.

It’s a thermal wrap. Protects battery from heat/cold.
Is it needed? I would not replace it.
 
Thanks Elliot. We might replace it with a generic thermal wrap, when the battery needs replacing. Car is parked outside, and summer sun here in CT will bake the battery.

Wow, I didn't realize the summer sun got that bad in Connecticut.

I've only had a couple of cars with them, and never saw the point, unless you're someplace very cold.
 
I look at like this: the battery is in the relatively closed engine by, just under a metal hood. Despite hood insulation, direct sun on the hood, when the ambient air temp is 80F, raises the temp under the hood to around 120F.

Sort of like how a closed car in 80F sun, becomes over 100F. Pets - and kids - die.

How many cars have you owned over the years?
How many of them had battery wraps?
I tend to think any (or none) fireproof insulation would work. As to how much longer it will prolong the life of the battery, who knows?
 
"How many cars have you owned over the years? Can't even remember, but probably close to 15.
How many of them had battery wraps? Probably every car I've had in the last 20 years.
I tend to think any (or none) fireproof insulation would work. As to how much longer it will prolong the life of the battery, who knows?" Who knows - exactly right! Reminds me of the old research dilemma: How many people's lives will be extended, if they wear warmer winter clothes in the winter, than the warm winter clothes they wear now?

I think we'll wait 'til we replace the battery, and get a "generic" thermal wrap, ca. $15, at that time.
 
I had my share of cars over the years and never even heard of a battery wrap until today.
