SOURCE: The bolt threads are stripped on my auto battery.

If it is the bolt that is stripped you can buy a new bolt at any parts store, if the threads in the battery are stripped, well you can get one of those at the parts store as well. You can probably rethread the hole to a bigger size, or use a heli-coil thread insert, but I have never tried one of these on a battery and dont know how well it will work out.

SOURCE: my invacare pronto m51 wheelchair

Did you replace both batteries? How old is the chair? Sometimes the on-off keypad becomes worn and does not make contact with the on-off switch. When charging the joystick lights can light up but after unplugging they should remain on. When you plug in the charger look under the rear cover at the charger you should see 2 lights, one red and one yellow to indicate that you are charging the chair if you do not see both lights lit then the charger is bad or has a blown fuse. Only a Tech will be able to tell what is wrong. If Medicare purchased your chair then they will pay for most of repair costs. Contact your provider or a repair service company

SOURCE: I want know how to

I am confused by your description of the process you are using to remove a battery. If you can not charge the battery in place then there should only be three bolts to undue to remove it. There should be a rubber wedge near the bottom of the battery with a bolt going through the center that holds the battery down. This bolt needs to be removed and the block taken out to be able to lift the battey out. To remove the cables start with the negative one so that if you touch a metal part of the vehicle with the wrench it will not short to ground (put negative back on last for same reason) then positive side. It should be a cable side mount type battery with small bolt heads that actually undue a larger (approx 3/8") bolt that goes into the side terminals of the battery. If you have any further questions please reply to my solution.

How do I get my pronto m91 out of charging mode?

The M91 has an onboard charger.
