Query: Buy the thumbwheel or sliding type

After it's been laying around for a while, you try to use it, but you can't until you find and replace the dead battery. So you use the thumbwheel.Or, the battery is good, but the motor spins and nothing moves because the drive belt (glorified rubber band) broke. Now you have another thumbwheel adjustable wrench.
