WOW! This should be a sticky (or in the FAQ). You guys are awesome!

What a timely post, as I need to replace the battery in the Sport and was looking for a non-wet cell battery to do it. I'd like to do an AGM if I can find one to fit...

The battery in my bike is a YB16AL-A2, but I can't seem to find a cross-reference for an AGM replacement. Can I just look for another 16 and hope it fits the battery tray?

Where did you find your AGM bettery? Was it an exact match or did you find one that was "close" and go with that? Are all Deka batteries AGM? What about this one:

Antti is awesome, not me :thumbup: .

I checked my regulator at still bike, at idle and at 5000 RPM.

The top voltage I found was about 15V and at idle was about 12,5 - 13V.

In the Electrex manual I read the top voltage was about 15,4V.

So, I thought all was OK.

Also, have I to check it when the bike is running?

Ciao

great post jon!

unless u ride every day though, any battery installed in a 907 will go dead prematurely if not constantly connected to a trickle charger. this is due to a ducati design flaw. we've all heard the various explanations as to why: the clock, (the most favored theory), dirty fuel filter, on-board computer, amoung others.

further complicating matters is the rectifier issue. the stock 907 rectifier is, at best, a marginal component. they're famous for short lifespans and spotty performance. so even if ur riding every day, unless ur one of the lucky ones whose rectifer is working as designed, u may very well be draining ur battery while riding!

ducati's answer to this problem is simple: buy a trickle charger! only an italian or british bike manufacturer could get away w/ this. nobody would accept this "solution" from a german, american or japanese bike manufacturer. it's part of the joy of owning a ducati. u gotta love it!!

i'm not suggesting it doesn't pay to buy a good battery. but if u don't have a trickle charger, ur wasting money. a good battery will last longer than a mediocre one, but w/o a trickle charge, even the best battery won't last very long in a 907.
