Hello, After fully charging my mother's Jazzy power chair overnight, the rear battery indicator/pointer shows zero meaning it's fully charged. I leave it unplugged all day and then by 5pm when I check the battery indicator again, it registers 2, which means it's no longer fully charged. After driving it about 200 feet, the three green lights become 2 green lights. The battery is only about 10 months old and the chair is driven less than 1000 feet per day by a very small women on fairly level sidewalk. Do I need to replace the batteries, or is there something else wrong with the chair and causing the batteries to lose their charge? Many thanks.

Thank you lennieg2000.

One more question, if I may. Let's say she breaks-in the batteries as you recommend for 20 days, but then later does not use the chair for much more than 1000' per day - does it hurt the batteries to charge them for 10 hours overnight when they may only have discharged a little during the day? (Her memory is unreliable at this point.) Is it better to have an off-board charger that will automatically shut-off when the batteries are fully charged? Again, many thanks. Thank you lennieg2000.

Sorry it took so long to answer wife had surgery and I was laid up awhile. What I would do is charge the chair at least once a week overnite after the breakin period is over If you visit regularly check that she doesn't run them down too low before she charges them. The onboard charger shouldn't overcharge the batteries so buying an off board isn't necessary Good Luck Sorry it took so long to answer wife had surgery and I was laid up awhile.
