The Odyssey PC925 in my airplane is now 9 years old and works as new. An old style lead acid Gill battery, brand NEW, would be dead if I didn't get a start on the third try. With the Odysey I can taxi down the lake on the battery, with mags off, it spins the engine so fast.
The script battery I bought for the Bee has an AGM inside, I presume it's a 925. I bought it 2016 and as of last week starts the car on the first crank..and if I happen to flood it I can crank numerous times and still never fails to get her started. For the Bird I gutted the old lead acid 27 script I've had since 1990 and installed the PC925 back in 2019. Figure it'll still be good in 10 years and either it won't be my problem anymore or it'll be easy to swap out.
Dart I cheated with a $100 topper... lol
