I installed a shorai battery LFX18A1-BS12, one size lager then the recommendation because I was worried about the VFR's drain and cranking. Lasted 6 years never connected to a tender only disconnected over the winter or when I knew I would not be riding for more then a week, never had an issue until my RR to stator connector burnt this spring. On my second shorai now.

For VFRs, I'm definitely continuing with LiFePo4 batteries. The first lasted 7 years, 2nd one is on the 3rd year.

Riding season is roughly April to mid October, so for winter I just bring it in the house, sit it on my desk.

Never needs charging, except when it's time to give up the ghost.

Volts at bringing it in the house... Late October.. 13.3 v.... Volts at reinstall time, roughly April... 13.3v .. essentially no loss. 

If the trend continues, I have at least 4 more years to go on the one I'm running now.

It will be interesting to see what's available then.

I like them, they just work, no hassles..

I wasn’t looking at any lead-in-acid style batteries. I realize there’s a couple styles of AGM (either the factory adds the acid or you do) but with AGM I don’t believe there’s any way for acid to drip because it’s absorbed into the glass mat and not susceptible to leaking. Well that’s my understanding anyway. I’ll keep an eye on it.

 

The battery I got is made by SigmasTek.

Well, ordinarily the acid in an AGM battery stays put, but I can tell you from personal experience that when your reg/rec fails in "overcharge mode" and you don't notice this until after a couple of hours riding at high speed on the Autobahn, acid will definitely be ejected onto the frame, shock and swing arm by the hissing and swelling AGM battery.  That's better than exploding, I suppose!

I’ve seen it on an ‘04 GSXR 750, as well. Suzuki refused warranty, claiming we’d improperly serviced the battery, despite the obvious R/R failure. The shop owner did the right thing for the bike owner, by replacing the R/R, battery, swingarm, rear wheel, and peripheral bits that were ruined, then, went after Suzuki. Corporate Suzuki can eat a bag of dicks.

I have a battery tender that has settings for normal and AGM but have no idea what type of battery is in there. Does it matter what setting the tender is on?

I know that AGM's are OEM for 6,7,and 8gens. Assuming your 5th gen wouldn't be on its original battery anyhow, then unless you have a Lithium Ion Battery fitted it's most likely an AGM battery, and if you don't see any small filler caps on the top of the battery that would also give the indication of an AGM installed.

Set your charger to AGM mode.

The OEM battery in my 1990 FL was an AGM battery (the kind you activate with an acid pack and then permanently seal with a plastic plug strip), but the OEM battery in my 1993 CBR1000FP was not.

Two years ago, I purchased a desulfanator/battery charger unit.  I bought it to tend to my boat batteries to help them last longer.  I've used it to tend my 8th gen VFR battery as well, but the battery is pretty new as it is and takes very little time (15 min max) to go from desulfanation mode to trickle charge mode.  As Winter in Wisconsin approaches, I'm wondering if I should leave the desulfanator/trickle charger connected for months at a time, or just periodically connect it.  The Interceptor is in an insulated (but not heated) garage.
 

"Anytime a battery is discharging, it is sulfating. Sulfation ruins batteries, which is why one that’s left unused goes bad. It’s imperative a battery is regularly used and/or on a maintenance charger. I’ve managed to get 12yrs out of Yuasa in my SV, via diligent use of a maintenance charger. I know they work and usually have five of them going at all times."

There’s a difference between trickle and maintenance chargers. You need to determine exactly what you have.
 

A maintenance charger can be left connected forever.

There was a time I would have agreed with you...

The only one of the batteries in that photo (taken in 2008) which did not eventually die--sitting on a smart charger--is the one in the back with the acid pack sitting on top of it.  And that's only because I never activated it!  

 

As I've mentioned elsewhere, my AGM battery killing days are over.  My next battery will be an Aliant YLP14 (14AhPbEq, 245 CCA), which measures just 114mm x 69mm x 90mm (and thus fits every bike I own).  I was LiPo-skeptical until Honda started fitting them as OEM equipment.  Good enough for me!
