I purchased the RG-25XC as a replacement battery for my Citabria 7GCBC. The prior battery was also the same item and it was installed in 2/2007. I maintain the charge with a battery tender when the aircraft is inactive for periods. Great product

Does what is should. Our old battery (exact same model) was 9+ years old, and the starter always had a bit of a lag to it. With this battery, it cranks up faster than Ive heard it in the 2 years Ive been with this club. There was a slight confusion with overnite shipping, where I was quoted $104, but the system tried to charge $197, but cust svc got it straightened out once I notified them.
