  • e motion m-11 battery rebuild

    I have a pair of first generation M-11 alber E motion wheels. As you might guess, the batteries are on their last legs. I am wondering if there is anyone out there who knows how to rebuild these that won't charge and arm and a useless leg. I use the wheels in my lift chair to do small projects around the house. Been getting hard to move the chair because of the loss of power. I am willing to send them to someone who is knowledgeable and capable of rebuilding them and pay for the rebuild, etc.. I am not patient enough or, not educated in arranging the C size batteries in series to do it myself.

    I know a guy that repaired my M15 Batteries - he took them apart - replaced and soldiered some new li-ion batteries...

        Bigtop1, I have been trying to find someone that would rebuild my M15 batteries so I glad you brought this up. Mac85, the person you had to rebuild your batteries how much did it cost and you that I hold they could charge after the rebuild?

          cowboysplace,...... I am the one looking to have my batteries rebuilt. Mac85 responded saying that he knows someone who did his. Hopefully, he will be able to remember who did his and, give me and, you a contact number.

            As long as you are staying with the same size and battery chemistry any experienced battery rebuilder should be able to do it.

              well Nonoise, You would think that would be the case. I will give it a try. I expect here in the greater Detroit area that there are a few around. I will do my homework and see if I can't find someone who is good enough to take it on.

                My Yamaha batteries for my quickie xtender power assist system are running, get this, $1,400 for one. Several years ago I got 2 for $1,500.

                Perhaps I can get a battery rebuilder to do mine.

                  It appears you could get it done in France for about $460.00 +. I don't know if it's legal to air mail them back and forth anymore. https://www.batteries4pro.com/en/Mob...heelchair.html That site says the chemistry is NiMh which is getting harder to find as they make heavy and bulky cells.

                  Edit:
                  Air mail should not be a problem since NiMh are not lithium batteries: https://en.wikipedia.org/wiki/Nickel...ydride_battery I'd forgotten about that earlier. Anyway if they are advertising it can be done there, you should be able to use that as leverage here.

                  Edit 4/28/17: France changed their price since yesterday: copy/paste 352,83 € tax incl. (352,83 € tax excl.) That's $384 US plus shipping etc.

                    The rebuilt batteries held charge just like new batteries, I can't remember how much it was since this was about three years ago – I already sold the wheels two years ago

                    I can call the guy and see if he is still interested in doing it - I remember that he had to buy plenty of 18 650 batteries to rebuild my batteries

                      18650 would be a common lithium battery cell.

                        I've heard that batteriesplus does pack rebuilds in electronics and power tools.

                          NOPE they don't do emotion - that is the first place I checked before I found the guy that rebuilt mine.

                          I just talked to the guy and he said that he can do it, BUT he can’t really give you an estimate because he doesn't know how many internal batteries are totally dead or if the electronics are still good.
                          He can give you an estimate once he takes A battery apart.
                          You would have to ship a charger with the battery/s or after he gives you an estimate … he is located in Chicago
                          I sent you guys a private message with his phone number

                            Sorry, but I can't see the point in rebuilding a battery and mixing the old cells with new ones.

                              I'm inclined to agree with you rustyjames. I have decided to give this project a try on my own. I opened the emotion battery pak and found 20 1.2 volt C size batteries. I will stop by Harbor freight and pick up a couple of rechargeable battery paks for their drills. They are rated at 18 volts and have a total of 15 C type batteries in them. Same voltage. Now, if I can remove them and replace them in my emotion battery pak, I'll have succeeded. So,............stay tuned for updates and progress. Nothing ventured, nothing gained.
