  • Great deal
Battery worked of course. I had to charge it up for an hour and a half to get it to full power but it's holding better than my old one. Then again it lasted 5 years. Hopefully this one will last another 5 years as did the previous one. So far so good

For the first time EVER I feel like I have purchased a high quality aftermarket replacement battery on Amazon. It's only been a week but I am impressed with the performance thus far. Will report back in a few months.
