Should I just leave the batteries on charge all the time?

That probably won’t hurt the batteries themselves. Although it might be a little overkill, the batteries would be OK in that situation. But it surely wouldn’t help the charger and replacing the charger can be quite expensive. Just keep the batteries charged each time you use the scooter or wheelchair, and charge it every few days if it is not being used. Probably the easiest way to do that is to plug in the charger at bedtime and unplug it the next morning.
