Concorde battery

[joepilot]

$612 with tax for a new one for my 24V J. Word is out how long these things have been lasting, & the prices are up accordingly. 

Old one almost 7 yrs old. No tender, but regularly flown & FL & CA it's life. Sat 10 days or so last month & start power wasn't crisp. JPI shows 23.1V after sitting 3 days in mild wx. But paranoid about getting stuck. Plus want to have a strong batt if alt quits IFR.

Good batteries. My 12V Concorde cranked my M20J at 5F and right away it started. Best performance if charged at 14.2 Volts.

follow the manufacturers instructions and do a capacity check. It’s rhe only way to know and really it’s required.

Completely agree.

Borrow a BatteryMinder, use its desulfating mode... Then capacity test...

Chances of any battery lasting that long and be healthy are slim.

Great news to share if you find success...

Also 23.1v on the bus is likely around 23.5 at the battery. But that’s only about a 25% charge. Try the battery minder for a couple weeks then a capacity test. Then call Aircraft Spruce. Over 500$ is free shipping. A couple cases of oil will put it over the limit.

Guess I wasn't clear. New one already  purchased and installed! After 7 yrs & a few signs, it was time. Not gonna mess with tests that will just prove the obvious. Just impressed on the longevity of the battery. And for $612, hope the new one lasts as long!
