I'm sorry if I'm putting this in the wrong place. I couldn't figure out where to put it.

Does anyone else use a Hoveround mpv 5? I just got one used but didn't get a user's manual and didn't think to ask the lady I got it from what the indicator lights mean. I bought new gel batteries and when I plugged in the chair, it said the batteries were charged but then when I went out today, the little lights rapidly went from green back into the yellow area. I don't know if that means I needed to fully charge the new batteries before using them or what. I plugged it in again when I got home and in about two hours, it showed a full charge again, but it's supposed to have a 15-20 mile range on a full charge and I sure wouldn't have gotten that today as fast as the batteries were going down. Should I be leaving it charging for longer even when it says a full charge when I unplug it?

Can anyone help me out?
