My first cold day of winter here, any where from -2 to +3c, my 10 month old battery would not start the bike. I got a genuine triumph battery charger with the wiring harness so I didn't have to take the seat of, no help. I then got the next battery upgrade from ytx20l-bs to a ytx20hl-bs. Still the same issue, get home from work when it was warmer, start up, charge all day and night, show fully charged, first thing in the morning, a couple of engine turns, then nothing. I changed the oil, checked the wiring after reading all the threads here, still nothing, was getting so frustrated, depressed, angry, all of the above. Had a price for a new starter, eeeeeeeeeeeek, no option. Last effort, another battery after reading about the odyssey pc625. Here in Australia another option was given to me, a cheaper yet more powerful yet still American, the Deka range. I went big, the Deka AGM ETX16, had to do a few mods, but, WOW, and WOW. Fastest I have ever heard the starter turn the motor. Highly reccommend it. There is a smaller one which fits straight in without mods but I was so pissed off with the other batteries I thought what the heck, cut the top rear of the battery metal strap, put a slight riser in the base so the battery wouldn't sit on the lip of metal since it is wider, it is secure with the rubber strap, it has pure grunt and staying power. Highly recommended after months of uncertainly of cold starts. hope this helps all who have suffered with my same issue. Cheers.
