I don't know that vac specifically but it seems to be a low end hand held vac. There is no spec for the battery that I found. That usually means they use a cheap rechargeable and I think the problem is the battery. I would contact the mfr since it is less than a year old. They can verify that from the serial number. If you buy another one, look for a NiMH or a Li Ion battery pack. It will cost you more but it will last a lot longer. Hope that helps.
