    Chair batteries

    Hi, I am planning to order Group 24 batteries for my Permobil F3. Is there a significant dropoff in performance of MK batteries vs. other brands?

    Try asking on wheelchair driver forum, there is a lot of information on batteries and charging there http://www.wheelchairdriver.com/board/viewforum.php?f=2

      Seems like MK is the way to go. I recall there being a specific MK 24 that was needed to fit in the F3?

            If your able pull the battery box before buying. If like on Mama's 350 due to space inside chair battery compartment you will need flat top batteries and not normal blade type terminals.
            It's a booger to fit batteries for sure.
            Be sure check if you have like seat elevator that 24's still has space hence if possible check size before buying, if your doing this as DIY project. Most brands of mobility batteries can be had with blade or flat top terminals that use screw to connect cables.
            Checked F3 online manual and shows use either Group 34 or 24's but didn't say required flat tops or not.

                Not a Tech but then sounds like 24's should fit, but if can check see if flat top batteries or just get flat tops anyway cause they come with screws to connect your chairs cables, like with blade terminals come with bolts & nuts with new batteries. Plus flat top be more room to slide box in/out.

                  Yes, it seems the flat tops are the way to go!

                    At least according to manual on F3 both batteries come out rear. Our neighbor replaced ones on Mama's 350 and one out back and other out the front, he hard time to get front even with seat tilted and footboard raised.
