Dead Battery
#4
I just bought a cheap ebay one and it's working ok so far. if you didn't have liquid in it, it sounds to me like you might be overcharging and boiling it dry. you should check the entire charging system.

+1 check battery while running and not running and see what the voltage is. If the voltage jumps waaaaay up while running or at say 3-4k rps then you might be over charging. I've had that happen with a car before but never a bike. If volts are just plain low could be the R/R.

R/R is likely fried, get a good one from a yamaha and do the swap.
Then for a battery, build a A123 cell one! That or the cheapest decent one is actually found at Wallmart, just be sure it is of the sealed type. That is: no drain tube on it.

I did buy one at Walmart earlier today. When putting the sealing thingy into the battery to seal the battery acid, I noticed how much better the new one sealed. It appears as though the previous one never sealed properly allowing the battery acid to boil off. I've only had the bike a month or so. It's been cold until Monday and it sat before I bought it. Or I could just be plain wrong.
Thanks everybody.

You'd better put a voltmeter on it to check the charging voltage.
Check it at idle, then at about 3000 rpm. If it's over 15.5V at the battery terminals, you'll fry that battery as well. Overcharging is what boils the water out of the battery. You never loose the sulfur from the sulfuric acid, that's why the sulfur smell. H2SO4 minus H2O = sulfur.

If the battery was brand new you should be able to replace the water/acid and charge it unless something weird has happened. I went through this & put it back in (after the regulator rectifier swap) and ran it another couple years. (kept the 2nd new one as a backup)

I have confirmed that I am overcharging my battery. My brand new second battery also boiled today. I've got distilled water in both and currently charging them. What can I do about the overcharging? I have an integrated LED tail light/ turn signals plugged in. No license plate light and universal flush mount turn signals in the front. The tail light came with a couple of resistors which I didn't notice until after I installed the tail light and it was working okay. However, from my itty bitty knowledge of electronics I don't see why that would matter since voltage in parallel is constant; having resistors on a branch of the circuit shouldn't cause the batter to over charge. I don't have much confidence in my idea though.

told you, I'm a little slow. Although admittedly, I'd like to think I'm a bit more observant than that..oh well.
Anyway just out of curiosity about how much and how hard is the R/R to replace?

Use the search function on this forum to read up on the R/R threads. TONS of information on there. Short answer is @ $70 and if you buy a plug'n'play (one that just plugs right in with no modification) it is an easy job. Again search the threads & do as much research as possible.
On a scale of 1-10 of difficulty this is like a 2.

I bought a 04-06 R1 R/R for $25 plus shipping yesterday. My boss is also an electrical engineer and knows quite a bit about motorcycles, especially Super Hawks. So I'm not concerned.
