How are you connecting your battery minder? Are you popping the cowl off and opening up the battery box to attach alligator clips, or is it possible to hook something like this up to the GPU port?

Mine is in the GPU door. Works great

I installed the interface kit on my engine baffle - accessible through the oil dipstick door on the front engine. Simple log book entry.

Update PIREP on Concorde RG24-16

I installed a new RG24-16 in Sep 2020, and it’s been on the Concorde battery minder whenever she’s in the hangar.

Tuesday morning hangar temps in the 40s, and got an initial no-start and VM showed 22v. 2nd attempt got engines started. On landing, she showed 24.6 on VM.

Friday, after three days on the ramp at the out-base (not on charger) with temps in the 30s, she showed 21v and no start. Had to use GPU to start up.

Landed after a 1.5 (day, VMC) and she showed 24.5v.

I’m thinking I got 4 years worry-free from the RG24-16, and it’s time to replace.

Go to Concordes web page and get the procedure for a conditioning charge or a deep recovery discharge. I’ve done them and have brought a battery back to passing it’s cap test.
You will need a constant current charger.

Hello everyone, I am a new member to the forum as I am a new owner to a 1963 C336 N480WL (hence "White Lightning"). The previous owner unfortunately is suffering dementia so I am not able to ascertain the reason to the following question...
This aircraft has TWO battery boxes (one on the pilot side - factory location, and another on the co-pilot side - above the fuel filter) and the positive & negative battery cables have been wired in series so I am "assuming" that there were 2 12v batteries (since no battery was in either box nor do these boxes allow a 24v battery to fit yet the dimensions fit a 12v battery).
Anyone ever heard that Cessna did a 2x12v from factory option? Any excellent reason to have it this way (I don't like the idea or expense of buying 2 batteries nor the issues caused with potentially imbalanced batteries/charging)?

I would appreciate the collective thoughts and wisdom from this group!

p.s. Having owned many aircraft since 1990s, I have enjoyed amazing results from Concorde batteries vs the Gill counterpart. It gets even better when you choose to utilize the specific BatteryMinder made for Concorde!

I can't speak to the 337 of 1963, but my 1961 310 used two 12 volt batteries from the factory to create a 24 volt system. They were both in the same battery box though.
