Have tender on battery for 5 or so if hours. Blinking red light as though it's not even hooked up and not charging anything. Is my battery probably fried. Kind of sucks that a single drain could ruin it, but maybe so.?.
Left lights on. Is battery fried?

What year is your Tenere?
I think Yammy is still using lead acid batteries in the Tenere.
If your battery is older than two years, then just buy a new battery.

Battery maintainers aren't designed to charge a dead battery. Put it on a regular charger. A desulfation charger would be best.

I would leave the tender on for at least day….you might get lucky. Make double sure your tender is hooked up correctly and is making good contact with the battery termInals. Otherwise, it is new battery time.

If you're thinking about the old style flooded lead acid batteries where you pour the acid in and screw the caps on, they haven't been used in motorcycles for years. Yamaha uses the Z series factory activated AGM (absorbed glass mat) batteries. I've been using a lithium battery for a couple of years. It works great and I've never had to charged it.
Get a 9v transistor battery and some 2 strand wire. Wrap the wire at the battery posts while connected to the charger. Just needs to touch the bike battery and will be pulled off shortly. Watch correct polarity and Touch the wires to the 9v + to + and - to -.
That should trick the charger into seeing a connected battery and turn on. May need to leave it connected a few minutes. Your battery MAY charge. But if you have to do this the bike battery is probably done.
Modern chargers need to see some voltage just to make sure the charger + is connected to the battery positive. With a dead battery it will not turn on. This tricks it into trying to charge.

I've done it twice. Both times I returned to the bike to find the battery dead, I was able to jump start the battery with cables; leave jumping vehicle off. The ride home was enough to charge the battery to the point where my 'Tender was able to charge the battery back to 100%. OldRider is right about the de-sulfating chargers being better than a regular 'Tender. I'm currently using the Optimate 3+, and it has "de-sulfated" the battery at least once. My bike/battery is just over 4.5 years old; OE. Still starts fine.
How did you leave the lights on? Turn off with kill switch and leave key in? When I turn my bike off (key, just like my car) she’s dead.

when you use the kill switch its very possible to walk away with the keys in it ,and left on..... don't ask me how I know this .

Thanks for the suggestions! I’ve gotten into the habit of using the kill switch. Must have spaced this time in a hurry or something. I probably should get a charger.
I got into the habit years ago, of using the side stand switch to turn the motor off. I got distracted, twice, and forgot to remove the key.
I pay much closer attention nowadays.
I left the key on, on my other bike and the next day the battery was dead. I put on the battery maintainer and green light like it was charging. Come back an hour later and blinking orange light.
Hooked up a regular charger and it charged right up. Don’t count your battery out just yet.

Most battery tenders will NOT charge a completely dead battery. You will need to hookup a regular battery charger for awhile to get the volts up enough for the battery tender to work. I learned pretty much the same lesson many years ago. Yes your old battery is most likely still revivable .

Not that you asked but if you end up needing a new battery I recommend going Lithium Ion. Not only are they super light, durable and mountable in any orientation but they are also fast charging from full dead. I've had several of them on different bikes and I will never go back. I have fully charged dead LiOn batteries in as little as 15 minutes and never more than 20... that's handy when you're in a hurry and you find that your battery is dead.

If it happens again, you can connect (in parallel), the discharged battery, with another battery (with charge) ... the charger will read the charged battery and start charging, which will be transmitted to the dead battery, after a while charging ... you can now connect the charger directly to the battery (now resuscitating)
We are talking, battery with the same voltage
Complicated??….imagine the same scene, but 500 years from now:Y'all are getting way too complicated.
Guys, today I took my Yamaha spaceship for a ride ... my alternator is not working ... and I no longer have oxygen..- Any suggestions?
those are going to be real problems
Outstanding multi-purpose battery chargers. I have a GENIUS2 and an older version GENIUS3500, they have worked great for me:
NOCO - Genius Multi-Purpose Battery Chargers
Our most advanced battery charger yet. Its a charger, maintainer, and desulfator. And it's incredibly powerful and compact.

We all (11 people: adults/teens) enjoyed the area very much, a lot of hiking and some rather low key "white water" rafting.
Checked out Asheville a couple of times, cool city with a cool vibe. We did the tourist thing and had some good food, brews and spirits.
Wish I had my S10 to ride around, some real nice roads/twisties for sure and I noticed a few quite nice trails off the slab.

Bought a NOCO Genius 1 from Amazon for about $30. Worked, reviving the battery from the dead. Didn't have enough volts to use other chargers, but this little NOCO one did the trick.
