Durability has been excellent. The insulation material shows no signs of cracking, stiffening, or degradation, even with repeated exposure to engine heat and road vibrations. The treated base mat also remains intact and functional, continuing to provide a solid, acid-resistant barrier.

Maintenance has been minimal, which is a huge plus. A quick wipe-down with a damp cloth is all that’s needed to keep it clean. I haven’t needed to replace any parts or perform any significant upkeep. Compared to previous attempts with less specialized solutions, this kit offers a level of sustained protection that is genuinely impressive.

Specifications

The DEI Cell Saver Battery Insulation Kit comes with a generous 40 inches of insulation material, measuring 7 inches wide. This provides ample material for most standard automotive batteries, with excess that can be trimmed to fit smaller or unusually shaped batteries. Accompanying this is a 12-inch by 7-inch treated base mat, designed specifically to absorb and neutralize battery acid.

This specific sizing and generous length of the insulation material are crucial for effective coverage. It allows for overlapping layers and ensures that all sides of the battery, except for the top terminals, are properly shielded. The acid-neutralizing properties of the base mat are a significant specification, directly addressing a critical failure point for batteries.

The manufacturer, DEI, specifies that the insulation material can withstand up to 2000 degrees F radiant heat. This high rating is far beyond typical engine bay temperatures, providing a substantial safety margin against heat-related failures. This is a critical specification for any component placed near an engine, ensuring its longevity and effectiveness.
