Dead battery/tenders

So today my battery died on me when I was at work and I’m going to have to get it trailered to the dealership tomorrow. Since it’s a 2024 and I got it last March it seems the battery might still be under warranty but I guess I’ll find out tomorrow.
I kept a tender on my older bike since I don’t ride it as much, but my rocket is my daily ride for work and I’ve put around 7K on it since March so I didn’t think I would need to keep it plugged in. Do you think this is a one off kind or thing or a common problem and I should keep it on a tender once I get a new battery?

if the bike is standing more than a week I attach a tender.

Exact same thing happened to me. Mine is ridden every single day on my ride to/from work. Last year it wouldn't start at work because the battery was too low. I believe either the battery or charging system is slightly under-sized on this bike. I installed a Bluetooth battery monitor and could see that the battery charge state would slowly decay day after day (even with continuous riding). I installed the triumph kit that adds a DIN charging port to the left side of the bike and now use a tender about once a week to ensure it's topped off. No problems since and the battery monitor keeps reporting 99-100% charge state. I've gone through 3 OEM batteries on my 2021 so far. I've been tempted to go the Lithium route, but I'm having a hard time finding one that has the necessary CCA and capacity and is sized correctly for our battery tray.

I doubt putting a tender on the bike would cause a problem, whereas not putting a tender on the bike clearly does. Right now my garage looks like a bowl of extension cord spaghetti with all the battery tenders.

My 2024 came with a bad battery. It was always on a tender but still failed within a year.

Got a new battery, followed the instructions to fill/absorb/charge properly, and have had no issues. I suspect they're doing something wrong in Thailand with the batteries. Either prepping them wrong, storing them wrong, or have a bad batch.

I appreciate all the feedback and was told it had a bad cell so they will replace it. The shop it wasn’t under warranty but I asked them to submit a request anyways as triumphs website says batteries are covered for 12 months from time of purchase and I’m still within that. Either way I’ll keep it tendered from here on out, just didn’t think it was necessary as much as I ride it but now I know.

Glad yours was an easy one, i have a similar thread going on my 2012, it refuses to start even with a new battery.

It's perhaps unlikely that the following video directly solves the problems experienced here in this thread, but I think it's a useful resource and a bit of background info that could come in handy, if your battery is losing charge and it's not immediately obvious as to why that is happening.

Just a little common sense and proper diagnostics could have saved so much time and expense. Not complicated, just lazy, replace this and that and hope for the best. Yikes!

To add to your battery thread. Testimonial. My anti gravity is 7 years old, i recently several months back had to move bikes out of garage to storage for remodeling, anyway, it was not on a tender, it was hooked up in bike. Its been cold for months, so i remembered i love that battery and brought it back to charge, it was OFF. No voltage reading, probably had gotten to cold and reached its voltage safety cutoff. I thought it was dead, but nope after sitting inside garage it turned on, and started receiving a charge. These batteries are smart. I feel like i got my moneys worth and its still going. Most balk at the cost of these 2lb batteries but id rather buy once every 7 years no telling how long this thing will last. Coming back on line fast. What happens is, say a relay stays open or anything draws on battery when its not charging, it cuts off at i think 11.9 volts, and the ecu will see zero volts, then you must put it on charger to turn back on, after it turns on and is charging you can start bike and it charges as normal, low battery fault light will go out, then you just find the problems draining, ive had this happen a few times and then its ok once charged past safety cutoff, mine is hd 900cca, they dont offer anymore mu exact model, and it will turn over a 215hp bike on first strike. These batteries are fantastic and for those FEW who want the lightest best battery and that hate fighting the dreaded click click, instead of vroooom when you push that button. Get ya one.
