CRS is an authorized Securaplane sales and service facility. Securaplane sealed lead acid emergency batteries have "no memory characteristics" and therefore do not require scheduled deep cycle maintenance as do Ni-Cads. In addition, Securaplane XL Series batteries are designed for a "no removal maintenance concept." All testing, including capacity, can be performed while the battery is still on the aircraft. The self-discharge rate is seven to 10 times lower than Ni-Cad battery applications. The Securaplane emergency battery systems have a five-year warranty on the electronics and a three-year warranty on the batteries. Applications include Challenger, Hawker, Gulfstream, Falcon, Lear, and other aircraft. For more information visit www.crsjetspares.com.
