Does anyone know if this battery is of good quality and has good autonomy?

these are the only ones you should consider putting in your chair

the F3 uses group 34 batteries
mk m34 sld g 12v 60Ah
here's a usa supplier,he does not ship outside the us,this is an example

Heres what you are looking for.
A battery that fits. If thats a GRP34 and a GRP24 will not fit (will it?) then thats the best you can do.
And heres what is important.

1. Low internal resistance. So not worse that 4.5mOhm. The lower the better. So all the cheap batteries at 6 or more mOhm are useless junk.
2. Cycle life. Obviously more is better. MK Gel is 500 cycles @ 80% discharge, with CORRECT charging. And around half that if you dont...
3. Ah. This is the size of the fuel tank. But you never get all of it out. The lower the internal resistance, (see 1. above) the more of this rated Ah is available to use in a powerchair. And the faster and mre completely it charges in the overnight time we have.

So Batteries like the Odyssey (IF they will fit, must be 260mm long, 170mm wide maximum, and height unknown on your chair) will always perform better with greater control and torque than any other battery. Because very low impedance. At high $$$$...

MK is best for most people, but MUST be charged correctly or will soon give low range, and die fast.

MK AGM and most cheap AGM are pretty much crap! But easy to charge with a generic charger.
MK Gel is the one worth fitting. But needs a correct charge algorythm, That means no mobility chargers... Unless you measure what they do carefully.

the F3 takes grp34. they fit inside a battery drawer that is too small for grp24. an F5 [upgraded F3] has a larger base that accepts grp24 batteries. yes,this is dumb

Personally, for myself, I wouldnt have a permobil for a big bunch of reasons if it was free.
Nor would I ever want any mid drive or front drive as I dont like the way they drive at all.
And also wouldnt buy any chair that didnt take GRP24 batts...
And that I couldnt fully service and repair myself, including proper full control of all programming, and a way to order all parts legitimately as needed.
And I also add to that, only 4 pole pole motors.


So when looking for a chair these things go top of my list. Permobil fail my initial list of essentials requirement tickboxes right from the beginning. I wouldnt consider one for my own purposes.
And thats before we see the prices (which are double that of which I would normally pay!).

So they definitely are not for me. Your mileage may vary.

Thank you all for the information friends, I'm going to buy the MK-6Oah. is the best choice for a standard charger.
