Group 22 (50 amp ) batteries are standard for GENERAL USE wheelchairs. Group 24 (73-75 amp) are Heavy Duty batteries for heavy duty applications. Often the group 24 batteries are used when the user is heavy or the chair is equip'd with an additional motor used for tilt/recline. Think of it a different way. Two people go into a restaurant and ask for a steak dinner. The fist person gets served first with a 10 oz steak. The other gets served with an 8 oz steak. Granted they both look about the same, but I bet the 10oz will do better. 12 volts is 12 volts, but the various amperage represents the energy and strength lasting of each battery. You can't put 75 amps, into a 50 amp battery. But you can put 50 amps into a 75 amp battery. What is most important is using the batteries recommended by the manufacturer for your chair and make sure that you fully charge those batteries each night. (now back to my 12 oz stekk or stake) Best Wishes In a message dated 9/4/2009 12:17:27 P.M. Central Daylight Time, [email protected] writes:
Hey guys, Will it hurt my chair if I use 22’s on my chair that has G24 batteries in it? I switched it and so far I don’t notice anything. Other than once last night, I started to drive forward and it just clicked. All the battery lights flashed, but the chair didn’t move. Kind of like I was reclined a bit and the safety prevented it from driving. But I checked everything, I was tilted up, reclined up, speed knob up, in drive mode. I turned it off and on, tilted and reclined a few times, nothing. But then I turned it off for the 3rd or 4th time and it started working. Just a glitch or something. No problems since then. I got new batteries for my chair so I put the old ones in my backup chair that had dead batteries. The repair shop who I would think should know if it was ok just said maybe, he wasn’t sure. Thanks, Greg
