I did electronics measurement and battery drain calculation for rocket3R 2022 - Battery, Turn signals

Yes, ~1 week and then the standard battery is dead - the same for me.

Just curious how much AMPS the heated grips use. The three settings on high, med and low. The reason I'm curious is when I first had the bike with under 500 miles I was on the freeway at 70 to 80 mph headed up I-80 at a slight 3% incline and the battery light came on. The heated grips were set at high but only had them on a very short time maybe 5 to 10 minutes. I shut the heated grips off and the light went out after about 3 minutes. I was in 5th gear so I wasn't bogging anything down. The battery light hasn't come on since and I did use them a few times usually on and off for a half hour or so but they were on med or low and never on high. Just curious what the AMP draw would be.

Nor sure what the amp draw is on the grips, but I always run on low or med.
Anything thats making heat is a high amp draw.

I have one of the older gen Rockets. I installed a voltmeter on my ride so that I could monitor things happening before the battery goes dead. With headlights on and the Triumph heated grips on high, there is no appreciable drop in voltage. I guess it helps that I also have led bulbs in my headlights, driving lights and tail light but even when I had halogens, my voltage never raised a concern. Also, I run my heated grips at least 60% of the time. On some long trips, I never turn them off. They are usually set on the low setting (only 2 on the Triumph grips) with never a problem with battery draw...

Just did a quick Google search and it looks like most grips draw from 3 to 4 amps. Shouldn't really cause a good charging system any problems.

Since it's "winter" here ( temp still above freezing ) I started to use heated grips on my GT. I also have heated Corbin double seat and not even once whilst using both I had a battery light come up. I didn't even know that warning even existed.

I have heated grips and heated jacket and gloves (grips off with those). So far, no warnings from the bike and a voltage meter on the aux outlet with usb shows adequate levels. I ride 5-7 days a week, so no battery failures yet. Good post/info- thanks.
