Mobility scooter batteries are one of the parts of a scooter that commonly needs replaced, no matter how well you take care of your scooter; however, you can make your battery last longer. When your battery does run out of juice for good, make sure you aren’t paying for something you don’t have to. Most insurers, including Medicare, will pay to replace your batteries, at least on an annual basis, so there really is no reason for your scooter to ever be immobilized, thus leaving you stranded.
Maintain the batteries properly. Just as you do with other parts of your scooter, maintain those batteries. This starts with keeping it charged and not draining it down all the time. In addition, don't expose it out in the open to harsh conditions and elements, such as heat or light. This, too, will shorten the shelf-life of your battery. If you are in a more harsh environment, you may want to consider a different type of battery (such as what's called a gel cell, as opposed to a wet cell).
Investigate payment options. Most insurers will cover the cost of regular battery replacements as they are, after all, considered to be medical expenses and are a common replacement with regard to scooters. Don't pay for anything you don't have to. Make sure you know what you are responsible for paying for, and what comes courtesy of your insurance policy.
Make sure you get the right battery. If you go back to the place where you got the scooter in the first place (a strong suggestion), be sure you have the right make and model of scooter so you can be matched with the appropriate battery for that scooter. If it's a merchant you have worked with before, the staff will already have your information on file or in a database, which will expedite the process and assure that you get the right battery for your specific scooter.
Develop a system. That way you don't have to arrange someone to drive you to the store, for example, for a new battery. You should be able to quickly order your battery via phone or online. Again, this is where a good relationship with a trusted merchant comes in handy.
Make sure the battery you are getting is a quality one with tremendous reserve capacity. Consider its physical size, cable hook-up and terminal type. In addition, check for the freshness of the battery, just as you would with the AA battery you use in your alarm clock. Most will have a manufacturer code on them which conveys the freshness of the battery, with a letter signifying the month (such as A for January) and a number signifying the year (such as 8 for 2008).
