Have been using Concord batteries in both a Turbo Aztec and a Ted Smith Aerostar for over 30 years. Never got less than 5 years of use out of them. And never ever had a charger on them. Great Batteries for sure.

In a Navajo, fitted November 19. During last year and this year NZ had some serious Covid lock-downs. It has been worse this year with me unable to even see the aircraft for 3 months. Hasnt been on trickle charge but started first time, very impressive. Both my cars were flat after 3 weeks and both with new pretty expensive car batteries(USD$300 each). So well done to the Concorde team, only problem is how do you improve it!

Batteries come well packaged with all airworthy certificates. Batteries perform very well and will purchase again in the future.

Q: What battery minder charger can I use for the Concorde RG24-20 battery?

You will need to purchase part # 11-14350.

Q: I am replacing a Gill G-246 battery with wing nuts on the posts. Is the Concorde battery the same wing nut configuration or do I need to purchase an insert?

Concorde batteries come with bolts, not the studs and wingnut like on the Gill batteries. They should be the same size so you wouldn't need to change the cables. I do not know of a conversion to wing nuts, you would have to fabricate that.

Q: Hello Aircraft Spruce Team, which would be the battery model if want to switch to GEL Technology from this one: CONCORDE RG24-20 PLATINUM SERIES SEALED LEAD ACID ??

We do not have a gel battery that is able to replace a Concorde RG24-20 battery.
