I was shopping around for a battery for my old chairlift, so I went online, and I found E J Stairlifts & Medical Supply. After talking to them, I inquired about just replacing the old one. They came right out, they gave me an estimate, and I ordered the new chairlift on the spot. They subsequently installed it for me. They were nice people, and they did a good job for me! The new chairlift works fine!
