People have posted that they got batteries and repairs done by
Buena Vista and also by Care.
Care is a full service medical equipment company (as opposed to others who just rent
ECVs), so they would be a better option.
But, things change and there may be other factors involved, like the brand of scooter, the type of repairs involved. So, it may be that someone was able to get repairs in the past that are not available now.
Getting things thru a medical equipment company is usually more expensive, so a store that specializes in batteries is going to be a better bargain.
I would suggest that anyone bringing powered equipment get the battery checked out at home before traveling so you are starting with a good battery.
I wouldn't top off that battery. My son's scooter battery was $150 to replace. He started out with a Go-Go when he was a freshman in high school, and we had rented for him when he was in jr high. He's in a power chair now. Anyway, the service repairman said never to charge for less than 8 hours, and given the cost of batteries, even if you can get it for less, I'd follow his advice. Charge every night at Disney for at least 8 hours.
Probably once or twice topping off won't make that much difference, but it's best not to get into the habit of it. We only charge DD's power wheelchair when it gets down to 1 and 1/2 to 2 bars. And, then we charge it for a full charge.
It's also important to know how long a full charge takes for your equipment. For some scooters, it can be as long as 12 hours. If you are out late, using the scooter and then up early using it, the scooter may not be totally charged in the morning.
My DD is on her second power wheelchair and both had their original batteries. We never had to replace one.
The first was replaced when it was about 6 years old because of problems with one of the motors. When they were checking it to see what was wrong, they assumed her loss of power issue was probably the batteries since they were the original ones. The batteries were fine and actually could still be charged to full capacity. Same with her current power chair, which is about 5 years old.
We were told batteries typically need to be replaced every 1 to 2 years, so following the advice above worked well for us.
