Guy at work has a 250 and it looks as though he needs a battery.

He can charge it and it will run for a while then hesitate and stall.  
It will restart if he chokes it off, but once the rpms drop it stalls out.

His rectifier appears to be working fine @ 14.5V.  
Walmart does not have his generic equivalent battery.  
Any idea where to buy one locally?

Or is there some other problem I may be overlooking?  
Could the stator be failing and where would one measure the output voltage?
