Review on Thermo Tec Products 13200 Battery Barrier by Donald Phillips

Thermo-Tec is the leading brand for heat dissipation throughout the automotive industry, not just battery packaging. So this battery is far superior to anything on Revain or the endless auto parts websites; I know I've been watching Check out all the products and you will see that they have the best models in the business. I have a 3500 diesel truck with two class 65 batteries. In the diesel world you need this film for two things: keep heat away to extend battery life, as engine heat shortens battery life significantly. And cold, freezing weather reduces your battery's ability to start a diesel internal combustion engine (without spark plugs), so the blanket minimizes extreme cold-start temperatures. However, if you consistently live in extremely cold temperatures of -15F and below during the winter, I would recommend an electric battery blanket. But above -10F it should work. I use Odyssey or X2Power brand batteries which are best for diesel engines and need to buy two batteries and plugs for the truck so I protect this very expensive investment with a Thermo-Tec thermal barrier.
