New Battery already dead

I have a 2003 883r. I had to replace the original battery about a month ago. Now the new battery is also dead.

This is what happend:

The original battery seemed to just wind down. I charged it once and it worked. But when I was out riding I stopped for fuel and it was dead. I got a jump and made it home where it was dead again. So I bought a new battery at Wal-mart. I had to put the acid in it, charge it and install it. The new battery worked great for 4 weeks. Today I went out to start it and click-click-click. I put a meter on it and it's reading 10 volts. I have it on the charger again, but I was wondering if maybe the bike isn't keeping the battery charged. Regulator maybe? or the starter going bad? Any help would be great. Thanks

UPDATE

I charged the battery today. The bike started right up. I rode around town, highway and sidestreets. I was oiut for about an hour. Got it home,turned it off, tried to restart it and click-click-click. The battery won't hold the charge. Could it be the stator?

Its something in your charging system, but not the battery.

This just happened to me last week. If you have a multi meter perform the folling checks. Check battery volt to insure it has at least 12-12.2 volts. Check stator for continuity with the ignition off it should be 0 ohms.Then with engine running unplug stator plug at voltage regulator. Idle up engine to 2000 rpm AC voltage should be at aorund 45-60 volts AC (20-28 volts per 1000 rpm) much more or less than that, probably a bad stator. If stator checks out and battery holds a charge overnight when removed from the bike, either you have a loose ground or a bad votage regulator. For me it was a bad stator, but I replaced the regulator and battery too becasue my was overcharging, which can fry a regultor and battery.
