Norb, I only use my chair when I go to the store with Dave. So, we usually recharge the night before or the day of. If, we do not take the caution of making sure it is charged fully, then we run into your difficulty. Guess ,I would charge it every night if I used it every day. But, we do carry the charger with us or it is in the car in case we need it.
We did expect the charge to last longer than it does.
Do they have batteries that last longer?
