BATTERIES

My 2 year old battery seems to be failing, it's sealed so there's not much I can do. So I bought one from batteryjack.com L=5.91 W=3.39 H=3.74
12V 7AH 12-7L SEALED BATTERY, $37.90, $7 TO SHIP!
Has anybody had any experience with this company, the brand is Power Kingdom!

A 2 year old should not be failing. Was it a OEM Yuasa? Have you checking the charging system?

Never heard of Power Kingdom, You are our test case on this one.

+1 to what mr mike said might ought to check the charging system, but one other thing is the bike ridden or looked at a lot? I was at the BMW/Duc shop and over heard the service guy trying to tell the owner that his battery was dead and the bike was under a year old, come to find out that his idea of keeping the battery charged was to ride it around the neighborhood to warm it up every now and then.... Prolly discharging more than charging

Good luck!

My experience with batteries is nothing last like the factory. Almost any of the cheaper batteries only last a couple years. Those are the ones from Walmart, Autozone, Advance and ect with little difference in price. Some last two years and maybe an extra summer as long as it doesn't have to crank to long.
I cheated and bought a lifetime battery from CycleGear so when it peters out they can replace it.

I have a pretty new Yuasa...Should I expect "instant-on" performance all the time? It was "instant-on" for a good while. Now, however, I think I can count to two or three before the bike starts.

I ride to work each day 6 miles each way, sometimes with stops at the store, and I thought maybe it wasn't getting charged enough? So when it died I but it on a trickle charger over night and day, when I reinstalled it, it was like a new battery again, but it only lasted 2 days then dead again. I know the charging circuit is charging because the headlight brightens as I rev the motor!
Thebattery on my RC51 only lasted 2 years also?

Does anyone know of a deep-cycle, gel cell battery?
I have an Optima Yellow Top (deep-cycle) on the F150 which is rarely started up, it holds the charge better than regular batteries.

Well I've had my $37 battery in for a while now, it looked identical to the $150 yuasa, starts the same, runs the same, just 1/4 of the price! I'm sure it'll go as long!

My '06 919 battery had a bad cell / intermittent short that caused issues with starting after it was warmed up, almost from day one.
Replaced it under warranty and it's been perfect every since.

OK i had recently had a 1983 honda nighthawk. that would hold a charge and then it would die after a coulpe of days riding it. It also had a headlight that brightened when i reved it. BUT... it wasn't charging. to really check if it is charging put a voltmeter on it (the battery terminals) and start it and at about 3000 RPM's it should be at about 13volts.. if it is any less then it is your charging system. on my old nighthawk i replaced the stator and regulator/rectifire. the magnet in the middle of the stator and the brushes were good. also the woring looked fine. But i had jumped it with a car several times and I believe my wiring ws shot. because jumping it w/ a car battey overloads a tiny motorcycle battery. So check and see if its charging the right way
Also theres nothing like the factory batteries for long lasting and in the mean time a battery tender like mencioned above it also a great idea. especially in the offseason!!

The first battery known, circa 250 BCE. Unearthed from a Bhagdad archeological dig amongst Sumerian artifacts. When filled with vinegar, it produces 1.1 volts. Use uncertain.

Check EBAY for a 919 battery and you will see two price strata: $95 to $110 for a Yuasa, and in the $40 to $55 range for no name batteries. The only real difference between the two is the cheaper ones are poor copies of the Yuasa, with shortcuts taken in the plate thickness, intracell and intercell jumpers, plate chemical matrix construction, vent valve configuration, etcetera, all with an eye toward cutting costs and getting a battery that initially cranks faster than an equivalent new Yuasa.

There is, however, a price to be paid, and that price is longevity. In order to make a "hotter" battery, the plates are made thinner in order to pack more into the available space. Every battery's positive plates erode, and the thinner plates in the economy batteries usually fall apart in a year or two, obviously ending its life, usually right after the expiration of the warranty. It just won't crank the motor over one morning.

Yuasa knows their stuff. My '02 needed a battery right after I bought it used due to sitting in New Mexico for over a year, and its replacement is approaching 5 years old without showing any signs of weakening. Definitely worth the $92 it cost.

If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.

Exclamation Dead 02 Yuasa

Finally killed my 02. Got a OEM for 109.95 119 with tax at the local dealer. Genuine Yuasa no weird stickers. Six years of service, and I'll pay premium price for reliability. I'm keeping this bike at least six more.
