I am on at least 4 years so far on this battery. Been cared for (mostly put on a Battery Minder trickle charge/maintain/desulfate). And aircraft has usually been in climate controlled environment when not in the field.
This battery is starting to show signs of weakening if I don't get my usual quick start during starter engage. I have not had a chance to do a capacity check yet.
From reading some past posts, it seems this is a good life and performance. I am wondering if anyone has gone much further with their battery life on this model battery? And if they have gotten longer life; suggestions on how they have had such success?
Also; does anyone suggest another make/model of 24 volt battery for the RII? Or any distributor better than Aircraft Spruce for buying the battery.
Thanks very much to all for your input and sharing ideas.
I think 4 years is a pretty good run for this battery. If a Gill went this far I would fall out of my chair! Batteries are getting better every day.
I change the battery (Only use Concorde XC's) every 36 months on my Beta II (probably half the price of your 28v model).
I go to places where it better start without any problems, and I'm just a recreational guy.
For the less than $10/month a battery costs, it's cheap insurance for me.
If I was at 4 years like yourself, I'd be ordering my new Concorde Battery now !!!
