I had purchased a replacement Yuasa YTX9-BS battery about a year and a half ago for the Kat. During this time, it spent a considerable amount of its life on a battery tender with no load. When I was rebuilding the bike, I had swapped it out for the dead OEM Yuasa where it discharged a few times (the the point of no lights on ON, bike totally dead) It did get hit once or twice by a battery charger for cars set to 75amp engine start.
Now that the backstory is out of the way, I've been keeping this on a battery tender (a proper one, 1.25A) and I haven't had a problem on initial startup for my last 3-4 rides. Went on a 20 minute ride, left the bike off for less than an hour. Left from there 15 minutes to get some food, in and out in 10 minutes, Kat won't turn over. Starter motor chugs slowly, then gets progressively slower until it does completely. Dash lights dim as well. Had it on the battery tender overnight, battery reads 12.4 volts on OFF after it settled from removing the tender. Bike turned over, but since the engine was cold it died due to improper choke. Starter would not turn over one a second attempt, same symptoms as above.
My question is, did I blow a glass pack in the battery on a ride, or was it a combined problem of hitting it with the 75A plus multiple deep discharges that sucked my cold cranking amps? Also, would it be worthwhile for me to get a larger capacity battery? I read from CP's site there are a few that will fit the compartment that have larger capacity and more CCA's.
