How long do they hold a charge for cordless edger?

I use in my Black & Decker weed whacker and they typically last about 15-20 minutes per charge so I keep a few of them charged up when doing yard work so I can quickly swap them out. Lifespan is about 3 years until they need to be replaced. I live in PA and so use for about 7 months per year.

Will this work on a b&d nlp1800 gator
