Battery blanket confirmation

[Richard320]

Today I upgraded to an H8 AGM battery. But before I did that, I did my research and ordered a new battery blanket.

Part 5033397AE is in fact the correct size for anyone who plans to do this in the future.

Note: I had jumper cables hooked from an engine bolt and a lug on the underhood fuse box over to my Jeep to retain battery memory while I did the swap.

Thanks for the info! I just did the H8 swap. What exactly is the purpose of the blanket?

Among other things:
To mitigate the temperature-induced stresses inherent to living in an engine compartment.
To help maintain a consistent battery temperature so charging cycles do not shorten battery life. These days, battery charge rate is controlled by the ECU, which sets power available to the alternator for charging based on battery temperature. Some, if not most, vehicles will have a battery temp sensor, usually in contact with the underside of the battery, so the charge rate can be moderated.
The cynical among us might also add that this blanket makes checking electrolyte level more difficult, for those who choose not to trust a "maintenance-free" battery.

In addition to the previous responses, I’ve found that battery blankets are the preferred nesting location for rodents. So, there’s that.

I googled the part number and found the cheapest. It was some mopar dealership with an online store as well. v

Don't take your battery's binky away

I can confirm those little $*%@#! do like the battery blanket and had my new truck less than a week. I guess they liked the new truck smell as much as I do....

The purpose of a battery blanket is to insulate the battery from extreme cold temperatures. They serve no real value in warm or moderate climates.

Do you have the link for the new blanket? What brand of battery did you go with? Thanks in advance.

I went with a NAPA battery. Just plug that Mopar part number into google, select the shopping tab, and go wth the cheapest. That's what I did.

When I look at the battery blanked for h8 after shipping costs I couldn't find it for under $25. I can make one for $15.
