I just got back from a 2500 mile trip...left my camper in New Mexico and drove back to Nevada with the bed full of solar panels (got 16.8 mpg at 70mph all the way home, btw...don't think the solar panels helped much ). Anyway, as soon as I get back to the ranch, it is a cold night. The following day I open the hood to check everything (leaving to go back to New Mexico soon) and I notice the battery blanket on the passenger side is completely shredded! I knew immediately that some varmit had made a nest with it and looked in the engine valley...sure enough, ma rat had made a nest and was taking up residence! So I prod her out and then fish out the remains of the battery blanket.
Yesterday, I go to Reno and visit the dealer . "Say, give me one of those battery blanket thingies for my PSD", says I. Parts "guru" says "We have to order it and it will cost you $37.50...in advance" !!!!!
So, my question is...Any ideas on replacement other than stock? I'm thinking of Dynamat applied to the battery directly...What do you all think?
That price doesn't seem all that bad.
And I can understand the dealer wanting the money up front. I have a large cache of special order parts at my shop that I cannot return or get paid for. Customers coming in and asking me to get a part and then they never return my calls.
I do the same thing now - require pre-payment. And in some cases, it's "all sales are final". No returns.

Wow!!! Not what I expected to hear on the price...I think of it as legalized theft. I agree on the pay up front issue though...no one should have to be stuck with a part they ordered for someone else. But I am going to pass on the insulation blanket...I could hire people to knit a blanket for the battery cheaper than that.
might want to hunt in some local junk yards. good thing you checked with the dealer first, cuz a lot of times the junk yard will want more. doesnt hurt to try though. that and fleabay.
Like this part, lots o money at the dealer. not too bad on fleabay:

Just be glad it was a blanket instead of the wiring. Varmit got under my hood on a Chevy diesel on time and it took me MANY HOURS to re-wire, reconnect and splice the wiring back together.

That sucks....mine have started to just get old and break apart kinda like a dry-rot...was thinking about replacing both.... thin I will head over to fleabay to have a gander.
Can anyone tell me the purpose of the battery blanket/wrap? My truck has one on the passenger side only, but I'm not sure if that's how all are or if mine's just missing the driver side one. I don't really see any purpose to them. Maybe to keep them warm at night so they don't shiver?

The battery blanket is there to protect it from getting overheated. Heat is what kills a battery. They last the longest if mounted away from the engine compartment.
...like in the bed. I'm planning to move mine there.
Several benefits:
Open up space in the engine compartment.
Get batteries into cool air - where they SHOULD be for longevity.
take 90 pounds from in FRONT of the front wheels and put it BEHIND the rear wheels. That has to help balance that big lump of iron just a little bit!

Are they all supposed to have them? Mine doesn't have a blanket over either battery. Never has since the day I got it used.
I was thinking of using that aluminum foil lined bubble insulation that you can buy at hardware or lumber stores in rolls. I can't think of the name of the product but I've used it to wrap my waterheater and outdoor tanks. I'm sure it could handle the amount of heat that there would be under the hood and protect the battery.
Actually, the insulation, as it is put around the batteries, won't prevent them from reaching high temperatures. It will only slow down the speed at which the temperature increases (or decreases). That might help a little, but I can't believe it helps much.
I guess, hypothetically, they (engineers) assumed that the engine would only run for a certain period of time when it is hot out, then it would be shut off - and, of course, underhood temps would start to drop immediately. Problem is, here in SoCal with summer temps exceeding 110 degrees, underhood temps stay high for a long time after shut down. And, if underhood temperatures are still high, the batteries will continue to absorb that heat whether they have an insulating blanket or not.
There are only two solutions - 1) isolate the batteries with sheet metal or plastic and duct air to them so they will be well ventilated, even when underhood temps are high. Or, 2) move them to another location.
I need to move mine before these batteries die, so the new ones will always live in a low-temp environment (well, relatively low, anyway).
