If you have managed to get a mobility scooter, either by paying the costs for it upfront or by getting your insurance company to cover some or all of the costs, you are going to want to make sure that it lasts as long as possible. You are going to be putting a lot of weight on the scooter and are going to be depending on it to maintain your current level of mobility and quality of life.
Many people who have just started wearing hearing aids aren't happy at the life of their batteries. Many people compare their hearing aid batteries to watch batteries and expect them to last for the same amount of time, since they are a similar size and shape. This is inaccurate because hearing aids need a lot more power than watches in order to function correctly.
Hearing aid batteries, depending on the size, will last between a few days to more than three weeks.
