After reading some battery threads here (and I would have posted there if I could find it again :???, I am exploring replacing my cub battery before it gets weak. I have the STC that moves the battery under the rear seat and uses a PowerSafe SBS J16 to start a O-320 160hp Lycon conversion.
Does anyone know how to determine battery age? I saw a method on Aircraft Spruce using the last 5 numbers (2 digit year, 3 digit day) but that doesn't work for mine. I've owned the cub for a year and the STC was applied in 2006. I've found no other log book entries for battery replacement. I assume this would be an expected entry, right? 15 years seems like a long time for any battery to last.
I checked the battery voltage at 12.8v with the master switch and avionics switch on not long after a 1 hour flight. I don't have a load tester.
I'm posting a picture of the battery in case anyone knows how to decipher the age.
Thanks for your input.
