To keep the battery in good shape in winter is not an easy task. Since October I fly barely once in three-four weeks mainly due to weather. In last two occasions I needed external power. I pulled the battery out and managed to charge it professionally.
It would be nice to plug a charger to the external power receptacle, cigarette lighter or wherever after a flight (the disassembly of the cowling would be not necessary) and the charger would take care of the battery. Charging it to full capacity and keeping it charged without risk of overcharging until the next flight maybe couple of weeks later.
I found some interesting gadgets in the Internet like BatteryMinder -
Battery Minder for 24 volt Aircraft Batteries Do you have some experience with that kind of chargers?
What is needed to use it that way on my Cessna 172S? Where to plug the charger? The external power connector would be the best option but will it work? There are some cables sold as accessory to the charger like this one
Charger Lug Harness: BatteryMart.com If I am correct, I could mount this cable to the battery and the other end can be connected to the BatteryMinder.
Thank you for your opinion.
