The young guy working there told me 20 minutes. I walked in 45 minutes later. He told me, "just one more minute its almost done" then proceeded to walk behind a little area and must have thought I couldn't see him. he then started to actually swap my battery. 50 minute wait for a 2 minute job. Don't waste your time going here. I can except running late but just be up front with me and don't lie. The price wasn't horrible and the job was done correctly hence the three stars. Can't knock a business too much for one employee.
