I've had my Hoveround for 3-1/2 yrs. Original batteries lasted 3 yrs. Bought new batteries from Hoveround & technician came out & installed. Batteries went out in 3 months & then Hoveround sent replacement batteries as the batteries are warranted for 6 months. These replacement batteries went out after 2 months & then Hoveround said they only warrant batteries 1 time & after 1st time of sending replacement batteries for a bad set THEY sent, the replacement batteries are not warranted at all. So for 3rd batteries I bought from Amazon - 1/2 price, no shipping cost & 1 yrs warranty. However these still won't hold charge & my son took apart Hoveround & found 1 rear tire had worn out inside & "might" be causing enough drag to cause batteries to discharge when using. Bought new tire on Amazon for 1/2 what Hoveround charges, but didn't help as I still have to charge it every time I use it, after about 10 minutes run time. Very comfortable chair, but their service is almost nonexistent & I would not buy another one. Had to pay entire cost of chair myself as they said Medicare wouldn't cover even tho dr. & 2 different P. T. said I needed it. For it to last only 3-1/2 yrs for what I pd for it is highway robbery. When Sr. Home I live in said I needed tie downs, I called Hoveround & they did put metal rods on chair underneath the seat for tie down & much better than cloth tie downs, but had to pay labor & cost of metal tie down rods. These should be on chair before they ever deliver it originally. Still don't know why batteries keep having to be recharged after 10 min of use & don't believe Hoveround will help.
