TSC for me as well...working in a parts store since 1990....I’ll leave you with a game to try before you buy...parts stores change suppliers often. Before you buy a battery, look at the sticker on the front. When suppliers change, they use up the previous stock and many times slap their sticker over the previous. Nonchalantly try and peel a corner and reveal what name you are getting. When playing with stock my high score was 3 other (different)name brand stickers under the outer most.:-)
Tenders are great, but I’ve had more fail than still work. Check them often! A load tester is your friend!
