This battery wrap gives you the ultimate protection against leaking battery fluid. The black felt material is treated with a proprietary material that neutralizes acid. It is also a big help for you custom builders wanting to protect delicate parts of the bike against excessive heat. The highly reflective surface of this wrap is capable of withstanding radiant temperatures in excess of 1050°C. V-Rod owners especially want to take a good look at this, since their battery is flat mounted and therefore more vulnerable. The kit consists out of an 8" x 40" acid-absorbing and neutralizing felt wrap, an 8" x 40" aluminized thermal barrier and an 8" x 12" acid absorbing/neutralizing felt mat.
