Hi everyone
I bought some new MK 40 AH GEL batteries for my spectra plus wheelchair. I bought them on August 8th, so they have had a few charges to settle in. They were both balanced by connecting them together for 12 or 14 hours before installing, and the first charge was 12-13 hours, and each charge is usually roughly 9-11 hours per night. Most days I don't leave my house, and if I do, I do less than a mile.
Usually when I get new batteries the whole chair feels refreshed, slightly faster, I notice much better acceleration and decellartion and the torque on hills etc is improved.
However, with this new set, acceleration is still sluggish, torque is definitely much reduced, and the batteries run out quickly.
What could be the cause of this, and any suggestions as to what to do?
