I'm not sure if this will help but check for another number on the battery. Got replacement for a Packard Bell netbook which was difficult to find. That had um08a41 on it, another HP battery had an even smaller code -mu06. Searched Amazon with superb-choice printed after the batt. code. This is the result for the Packard Bell link. What's good with this company is you get the image of the battery which helps to identify.
Just found another one for my old Compaq, link. I've bought 2 from this USA company and have had no problems.
