Design Engineering010480 Cell Saver Battery Insulation Kit

This product worked great for my Nissan Murano Group 24F battery. My old battery had an OEM insulator, but the new battery is bigger. The old insulator does not fit, and there is no OEM replacement, so I bought this kit. The kit includes 40" x 7" insulation, and a 12" x 7" base mat which is a nice addition. I have included pics of both sides of the material. The base mat does not have a reflective side.I did cut the insulation to accommodate for the ears on my battery. For this particular battery which measures approximately 10.5" x 7.0" x 7.4" I cut off about 6" from the length of the insulation, and also cut two indentations for the ears on each side of the battery. This was so the insulation would be completely flush against the battery. I also cut the base mat to form, so it would fit into the battery tray. I would not have to had cut anything to use this product. (Not even for the battery tray.) I only cut to have a more professional look.However make sure the insulation is below the terminals and connectors to avoid any contact so it does not arc. I did test the foil side with a multimeter for continuity, and this will conduct electricity! So make sure not to get this close to the battery contacts. Also, it is dangerous to try and cover the top of the battery with this. So this will need to get cut if the battery is less than 7.0" tall. This is not intended to cover the top.I am very satisfied with how this turned out. The quality seems good. It took a little effort to cut with a box cutter, so it won't wear or tear very easily. I would purchase this product again for my next battery.

Good product,works great.Easy to use.

The DEI battery reflector/insulator seems to be working. The new batteries are not as hot as the old set they replaced. The only issue was the amount of the DEI product was about 6”-8” inches short for covering the bottom and sides of my FT825 Group 34 battery. Battery nominal dimensions: 10-3/8” X 6-3/4” X 8-1/4”

Works well and isn’t difficult to install, I would buy again.

Easy to install battery blanket. For Ram 2500 diesel, replaced batteries and was missing one blanket. Google search says that heat from engine can shorten battery life. I don't know if that is true, but it was worth the small investment to be sure.

If you using a lithium battery this is definitely a must. But definitely beware or at least think and don’t do what I did. When installed I did not realize that the out side was touching both of the terminals making them connect each other which almost made my vehicle catch fire. Pretty exciting stuff

Batteries dont really like being hot. Mine is right next to the turbo manifold. This helps the battery from cooking. It was long enough to where i was able to double it up on the short side of the battery that stares directly at the manifold. I did also tape up the bottom corners with some HVAC foil tape. It does what its supposed to do. The end.

If you see my attached image, please know that this kit does not include a way to cover the top of the battery, despite my attached image. Read below for details.This worked well for wrapping MOST of my Audi S3's battery, but it didn't cover the top or bottom of my battery (except for the non-reflective piece of felt on which the battery sits on the tray). So, I used some additional heat barrier which I already had from a different project (Thermo-Tec 13575) to put a flappy lid on the DE Insulation Kit, as well as putting a piece of it under the felt on the battery tray.Because boosted engines (both turbo and supercharged) generate more heat than normally aspirated engines, and I'm also running a Stage 2 Tune, when my battery recently died unexpectedly, I was worried that the additional heat generated in my engine bay was wearing out my battery prematurely. My other car is a supercharged Jaguar XFR (also tuned), but it has functional hood and fender vents to let the substantial heat escape AND the battery is located in the trunk, where it should be (for both better weight distribution and protection from heat). Unfortunately, Audi, in their infinite wisdom, placed the battery of my S3 very close to my turbo (which thrives on high heat) in the engine compartment.I looked at some type of better engine venting in my S3, but didn't want to cut holes in any of the body or do anything too invasive (I already have an upgraded intercooler, etc.). I also considered relocating my S3 battery into the trunk, but even with the spare tire removed, there didn't seem to be a good place to put it, where it would be somewhat concealed. So, I ultimately settled for this battery insulation kit, as well as adding a Turbo Blanket and wrapping the top section of my downpipe to try to remediate some of the heat damage. I haven't tested before and after battery temps since installing any of it, but I probably should soon, as one of my fears is that this insulation kit might actually be trapping heat inside the kit, rather than letting the battery breathe appropriately. Although, I have no factual scientific basis for questioning the functionality of this kit, other than not including a reflective shield for the top and bottom. If I do test it, I'll edit my review appropriately.

Although they stated on here it would not fit my battery.This product has no measurements here to see. I know it will fit most batteries and can be cut down to size, if smaller.Worked for me and easy to use.

Having had a misfortune of a fairly new battery becoming defective due to discharging due to either alternator not charging / or battery leak. Decided on extra protection for the battery found this item came from America. so far so go. i would recommend this for your battery protection.

This was easy to install and seems to do what I needed it to do

This product was easy to install. Although the tape they supply could be better to seal the seam. I added Gorilla tape to make sure the seam would not separate. I was glad it was 40 inches long and 7 inches high. Not much trimming to do.

This insulation is very tough and easy to work with. I was able to pull it around the battery without removing it. The tape that came with it didn't stay on, but that's a minor detail that a piece of Gorrila tape will rectify. I would recommend it.
