I went out to fly my aircraft last weekend and had trouble cranking over the engines. I was able to get the front engine started, but not the rear. There wasn't enough juice in the battery, so my annual is next month and I was looking at replacing the battery since it's coming up on 5 years. I have a Gill 242 wet battery, but they now make a Gill 242S sealed battery and it looks like the 337 is listed. But I would like to know if anyone is using the sealed battery now, does it require paperwork, or is it a direct replacement?
