battery

I can confirm that three years is a long run for an aircraft battery.

Will a Concorde replacement fit the original 337G battery box with any modifications?

Without any modifications? Yes, check the Concorde site for applicability. No modifications required to the original box

Today, my 2 year old G242 battery died. Showed 24.3v unloaded, but volts dropped to 9.8v upon cranking—obviously no start. Worked great two weeks ago. Use a Schauer 24v ground power unit and battery charger routinely. Thought it would be a good battery minder...but maybe the charger/maintainer hastened it’s demise? According to logs, prior to 2018, the bird got a new battery in 1988, 1999, and 2009. So, old Gill batteries were apparently pretty good. Thinking of swapping to Concorde. A&P votes for Concorde also. Concorde site calls for the RG 24-12 as the appropriate battery for my ‘77 NA G model. Anyone using this battery? Where do you like to shop for one?

Are there any Lithium Ion batteries PMA'd for the 337? They are taking over in the Bonanza world. Half the size and weight, far more CCA. Would love to have a LI option for our planes! Comes in its own box too, so get rid of that ridiculously expensive battery box, especially the $1000+ plastic battery box in late model 337s.

I may install one via 337 if no PMA solution is available. (I guess 337's for 337's is a tired joke by now on this site )

Welp, I followed your link which re-directed me to mcico.com for purchase info. It appears the STC for the Bonanza is $8035.00

Maybe I'll just stick with a Concorde RG 24-16.

My choice has been Concorde for the last 20 years. I have paid the extra for the platinum series and haven't been disappointed.

I change my battery every 3 years no questions asked. A lot of guys say if it starts it's good but that is not true. I am a serious flyer and routinely fly IFR, over lakes (big ones) and night so I have no problem with buying new and staying fresh. It's the one time you loose charging that will make a believer out of you.

I also use a Battery Minder made specifically for the Concorde battery. It stays on my plane whenever it's in the hangar

That can't be right. I must have linked to the wrong product. I'll check in the Bonanza forum I belong to and get the right info. The cheap Bonanza owners I know that have LI batteries would never spend that kind of money on a battery!
