I recharge my wheelchair every night, too. But, when I first owned my own scooter after several years, I didn't realize that even though the battery LED green light indicated the battery was fully charged, it only meant that the section of the U1/gel battery that was no longer dead was fully charged. I also noticed that it took less time to recharge. Probably because there were fewer areas of the batteries to recharge.
One day at MK my battery went from all green to all red and not running. I just asked a cast member where the nearest outlet was and recharged my scooter enough to get back to my resort room.
I was able to call Lake
Buena Vista Scooters and they changed out my batteries while at the resort. It cost a pretty penny. I always buy my own batteries now and change them out myself.
So if you own or rent your scooter, may sure to charge it every night. Make sure the electrical outlet is not part of the light switch system. Meaning that if the light switch turns off near the front door, it also turns off that one electrical outlet. That happened to me one time at a DVC resort a long time ago. I plugged my scooter in at an electrical outlet near the door and I noticed when I turned off the entrance light it also turned of the electrical outlet that I was plugged into. That only happened one time and I never forgot it. Make sure you plug it into recharge immediately when you get to your resort and try to charge it for the number hours the instructions suggest like 8 or 10 or 12 hours each night. Make sure you turn off the power during the day when you stop to save battery use. Some scooters do this automatically after a certain time, but I still turn off the power when I am sitting and waiting for whatever reason. I attach the scooter key to a stretchy band so that I can put it around my wrist. It is handy when leaving the scooter to ride a WDW attraction. Or if I was waiting in a very long line like for the standby line for the December EPCOT Candlelight Processional, I just turn the key off, but I still leave the key in the power slot. You can see the LED lights or power needle turn off to confirm that it is turned off.
If you have to recharge in the park because you forgot to charge overnight, you can do it while dining, etc..
This has just been my personal experiences when I was a newbie and everyone else may have other experiences.
I know when I go the parks that I may use my batteries every day for longer periods that when I am home and I am always aware of when I last bought my batteries and if I need new ones before traveling.
And there is no definite time for how long your battery may last compared to someone else because of the use by the patient or size of the battery and the weight limit of the scooter and the weight of the rider, etc..
Some people use their scooter all of the time and everywhere at home and outside. Some people don't. Some people just rent at WDW. So everyone's experience could be different.
It really is a learning experience.
But, as everyone has already mentioned.
1. Plug your scooter in to recharge every night until you are ready to travel the next day.
2. Try to teach yourself to turn off the power during the day if you are not driving to save battery life.
3. If the battery for some reason dies at the park, just ask a cast member where the closest electrical outlet is located to you. They are everywhere, but most nearby cast members are where they may be. And you may want to call the rental company and let them know that you think the battery is not holding a charge to see what they say. They might bring you another fully charged scooter. But, not, if you just forgot to recharge overnight.
