Great Battery!

Love this battery! Lasts so much longer than the small one that came with my machine. And, it was delivered the next day! Super service! And It fits in my case that came with the unit, a little tight, but it does go on ok. Very happy!

extended battery

The extended battery gives a person using a pressure of 3 about 4 hours of usage. It allows one to run errands and see the doctor. We aren’t able to use the original cover for the unit with the extended battery. Can’t get it to fit. Wish it came with an “extended” unit cover. The service was outstanding

Love my 8 hr battery

Surprised with next day delivery. I am so happy to now have the 8 hr battery along with the 4 hr that came with the machine. Hours go by fast in a day. I know that I can also recharge in my car as well as electric outlet, but if you always have to plug it in then, you are still on a short leash Recently got my machine and was so very happy, but now I truly have peace of mind. Thank You
