Gale Merliss at MERL does not sell individual ELT batteries for their products,but Aircraft Spruce has the latest, fresh batteries that they sell to customers. The Model # BP-1005 ELT was developed during WW II to be packed with cargo destined to be dropped by parachute to troops on the ground. The ELT could be tracked for pickup, It is probably the best ELT ever designed and has a Impact G-Switch that is activated in any 360 degree direction. Thangs for Aircraft Spruce for the good service.-Leon Johenning

This battery has a date stamped on it and after 2 years must be replaced.
