Wheel chair batteries come in a couple sizes.  What group size are they?

Some use the group 22 or 24 or 27, and other use U1

The U1 and 22 would be undersized already without being weak.  A weak 24 or
27 would be as strong as a fresh U! or 22.

Deep cycle
Group size 24 usually around 60 to 80 amp hour
And 
Group size 27 usually around 90 to 110 amp hour
Depending on age and quality of battery.

Most wheel chair batteries I have seen are usually AGM so would be toward
the higher numbers for their size.
