Is there a better battery than the Yuasa that comes on the 800EX.  Have not had my ride a year yet and I can't get the battery to keep a charge.  Had it on a tender for a while and not helped either.    Please advise.  Thanks guys

To many accessories?
That was my problem so I just ran a second battery, placed it under the seat, but I did have to cut out the plastic box cause it was too small. No more battery problems since.

Yuasa is a good brand. I wonder if it's an AGM battery (almost certainly) and whether dealers have to activate the battery as a part of delivery and setup? I know from ATV experience that there have been many cases in which the dealer has (presumably) given the task of activating the battery to some poorly trained or unsupervised shop helper who just shoots the electrolyte in and then immediately slaps it on a quick charger.
For an AGM battery this will doom it to a service life of less than a year where it ought to be good for seven or more years.
(ps. anytime you go to buy an Absorbed Glass Matte battery and you hear, "great, come back in an hour and it'll be ready" run the other way. They will ruin that battery in that hour. It needs the electrolyte bottles to be placed on the battery, punctured, and then let the electrolyte drizzle in at it's own speed. Then let the battery sit untouched for a good hour or more so that the electrolyte soaks into the mat. (The 'absorb' part of the name) Then place it on a slow charge no more than 2 amps on a smart charger NOT 2 amps on an old fashioned car charger, and give it eight or ten hours like that. Then you gave a tough strong battery for a lot of years)
Proper activation is essential for an AGM battery, it's not like your grandpa's old Diehard lead-acid car battery. Activate it right and you have a strong battery, do it wrong and you have a paperweight.
Just wondering.

Get a (Odyssey PC 680) they are the best and made for rough use mine is like 5 years old and hold up excellent and they are a sealed batter come fully charged  they have a believe a 3 yr replacement warranty not a pro rated warranty as most battery brands have expected life of these battery is 10 years I even use the odyssey battery in my truck which is a bigger one, Amazon has the battery you need for just over $100

Believe my OEM battery just took a crap.  Out of nowhere.  Rode most of the day.  Made one last stop on the way home (after I had left the group), and she wouldn't start.  Had a friend come out.  We jumped it.  It would run for awhile, then I'd lose the fuel pump, then it would kick back in, and finally able to limp it home.  Put it on the trickle charger and it won't hold anything.  Won't even turn over.  Dash lights up erratically, some clicking, but the fuel pump doesn't load up.

Sounds like it's battery-time to me too.

Battery replaced with the same Yuasa battery.  Back to running fine.

That's what I did...always safe with the OE specs.

Amazing how quickly they go from working ok, to absolutely nothing.  Almost like turning off a switch.

New battery came in on Tuesday.  Added the electrolytes like they suggest.  Let it set for awhile, then put my charger on it.  I have two chargers.  One is a smart charger, that won't charge anything that isn't somewhat charged, and the other one has multiple settings, one of them for AGM batteries.  So I used that one on the 2 amp setting.  It read 25% charged after several hours, then finally up to 50%.  So I threw the smart charger on it, and it almost immediately said it was fully charged.  So I installed it.  On the battery itself it says to charge at 3.0 amp for 5-10 hours.  The Yuasa website doesn't tell you how to charge it, just that it needs a charge.  Anyway, hope it's all good.

My smart charger is pretty fussy. It takes many hours or even days sometimes to show fully charged. But it drops all the way to like 8th of an amp depending on the level. It took over night to top my new one off. I would just put the smart charger on it over night anyway just to be sure.
