Yet another bad battery...

Bad luck?

I just had a cheap xtreme battery go bad, that was my 919 battery. died after 11 months, replaced for free under their 1 year warranty.

Yesterday I went to fire up my GSX-R and it wouldn't go, 12.x volts not under load, 3 volts once the fuel pump primed.

Yuasa battery, roughly 11 months of use. Hopefully motorcycle super store is willing to work with me on it since it was a dry battery with the acid on the side, I bought it because my GSX-R battery had some age on it, I left the new battery on the shelf for a year before adding the acid and putting it to use. So the battery is about 2 years old, just under 1 year with acid.

I just don't get it. My factory Yuasa lasted 6 years, my 919 battery lasted 2 years with me and maybe 1-2 years with the old owner.

Last year when I replaced both batteries I told myself I was going to do it right and hook up a battery tender to them. I swap the tender back and forth from the bikes, depending on what I'm riding and if Im not able to ride I would switch it maybe weekly.

Bad battery tender? bad batteries 2? really bad luck?

I've always neglected my batteries in the past with great resluts, now that I'm trying to be good with them, they have failed.

Sorry to hear about your recent bad luck with batts.

Proper battery set up is crucial to long life (and can be a PIA).

Certain motorcycles have a parasitic draw that can be a battery killer - that's one reason why it's a good idea to remove the battery for storage, need be.

Could of been a bad batch of batteries, haemonic vortex's, who knows.

Anyway, Yuasa does a decent job with these video's and other links on their web site.

I watched the videos on how to setup the battery, not the first time I've done one either.

Just seems odd, any idea if the JR tender could be killing them? Or... just bad luck.

I seriously doubt it's bad luck, they should last longer.

Is there any chance the Yuasa was a chinese knock-off?

I'm not sure how to troubleshoot the tender, good thought, very well could be if it is older.

New smart chargers are pretty inexpensive, might be a good time to upgrade.

Huh, Taiwan stuff is usually pretty good quality.

Is there any chance at all that we could blame Obama?

Maybe he held the shipment up at customs.

Although since acid came on the side it shouldn't have mattered.

I've read more failure stories in the lithium batteries than the lead acid. Plenty of guys here have OEM yuasa's in their bikes. Maybe a knock off? or just a bad one. every manufacturing company has faulty units every now and then.

I just called them and asked about warranty info. They said the yusasa batteries have a 1 year warranty...

Bike master gel battery has a 3 year warranty, might have to go they route next time. Plus it's cheaper.

Anyone have any ideas on bringing this battery back? I remember a friend of mine use to add fluid to batteries to get more life out of them. Not sure if I can pop the top off since it's been clipped into place. Might have 1 way tabs.

Yeah, cell phones are all going to lead acid batteries. And they're going to put wooden wheels on bikes soon.

Several years ago, I dumped a KLX250 in a stream in the middle of Eglin AFB wilderness. I cranked and cranked and cranked on that thing. I guarantee no other battery would have gotten me out of that mess.

Shorai's customer service is the best. Period. That comes from first hand experience, not Internet bull.

You are in Maryland, so it doesn't get tooooo hot, but extreme heat is tough on a battery. Is your garage very hot in the summer?

Another thing to think about is anything that may be draining power from the battery.

I have a GPS, that drains power, even when it is off.

So now I have it on a switched circuit that disconnects the GPS when the ignition is off.

Same old rant, but my 12-cell lithium is going on at least 6-7 years now. Still going decent; not quite as strong as when I first got it, but doing just fine.

Two year old ballistic in the 599 is like new.

Have you checked your regulator output? not going over 14v?
