No idea which to go for to replace this one, by bs battery I think. Was supposed to have had a new one on when I bought the bike but it's not lasted that long...since Feb. So either they didn't put a new one on or I might have a drain which I'll have to find
What batteries are y'all running?

If that's a BS battery (talk about truth in advertising) it's not an AGM (absorbed glass mat). Just something that you'd put in your lawnmower. Whatever brand, or type you go with, a YTZ-14S AGM is the number you want. I'm using a generic Batteries Plus, but it gets put on a Battery Tender nightly. Many here like the lithiums better. More juice and less weight. But that means more money too.

I've had pretty good luck with your basic AGM Super Start battery from O'Reilly Auto. They outlasted my OEM Yuasa.

I’ve had the 12S and the 14S which wasn’t much better. Eventually bought a Scorpion stinger lithium battery with 385 cold cranking amps, it’s probably the best thing I ever did to a Tenere, it doesn’t sound like the battery is half dead anymore. Makes me grin every time I start it.

What Cycledude said. Spend the money, get a lithium iron battery, and never look back for at least six years,
swopped my yuasa 14s to a noco nlp14 awhile back now

I put a YTZ 14s in last week. Lithium saves weight but I believe take a special charger. Keep that in mind it you are making the swap.
More than that is that if you can damage lithium batteries (kill their life) if they go flat as the OP said he has done at least once.

My 2012 came new with a 14s. I replaced it after 8 years with another 14s, just because it was getting old. I've never had any battery issues or hard start on this bike.
FYI, BS and Z batteries are both AGM batteries. The difference is that the BS battery comes "bottle supplied" which means it has an acid pack that has to be put in the battery. The Z battery comes with the acid already in the battery and the battery is factory sealed.

I installed a lithium to replace the almost new 14 battery which was moved to the DR650 to replace an almost new smaller battery. Both exhibited a little bit better turn over though nothing earth shattering. And the cost of a lithium battery charger.
Went I went into Batteries Plus, the salesman verified that I had ordered the correct battery; YTZ14S. It was not listed as compatible with the Tenere. It is compatible though.

You do NOT need a special charger for lithium iron batteries. You just have to make sure the charger you use does not have a desulfating mode. I have used Deltran Battery Tender's on mine for years. Not that they actually need it. They'll hold a charge for well over a year.

Without plugging my lithium noco into a charger, it can last about 7-10 days before it goes flat. Once it is flat, you have to force charge it because the charger won't recognize that a battery is connected.
When you say "flat", does that mean it won't crank/start the bike? Is that normal?

There is something wrong with either your battery or your bike!
