I use this on an airplane too. They know their batteries!
Not sure which aircraft and batteries you have.
A few years ago, one of the aircraft I maintained was notorious for having batteries, the pink ones, fail just a few months outside of warranty. The aircraft I am mentioning utilized two 12v batteries, wired in series to supply 24volts. Ultimately, after replacing 4 batteries within 5 years, and a couple of missed flights, I did some homework to make things better.
Having had good luck with Concorde batteries in the past, I spoke with their engineers. They made suggestions of which batteries to install AND suggested using a Battery Minder brand maintainer. Ironically, the battery manufacturer went into detail about how the Battery Minder is superior to other battery maintainers.
In regards to the aircraft, with Concorde Batteries installed, and the Battery Minder utilized whenever the aircraft was not in use, the aircraft had over 4 years on the Concorde Batteries and more life in them when it was sold.
I have utilized the same process for the Spyder. I use a Battery Minder brand maintainer, Model 1500, which has desulfation circuitry. The Battery Minder is connected via the rear trunk power port after each ride. I just replaced our original battery in the Spyder. It could have gone a bit longer, but was making the starter lazy. The oem battery would have been 6 years old in January for us. Not sure how long it was at BRP waiting to be installed, so likely pretty close to 6 years of use.
FWIW, since the Battery Minder 1500 is smart enough to charge or maintain, I installed the new Yuasa Battery onto the Battery Minder prior to installing it into the Spyder. Accomplished voltage checks prior to charging and after charging to ensure proper voltage. Like before, after each ride, it gets put on the maintainer.
