The four sizes of hearing aid batteries are 13 (orange), 312 (brown), 10 (yellow), and 675 (blue). This is made easy for people because the simple fact of the matter is that when people start to lose their hearing they also start to lose other senses as well such as sight.
Having the color code to meet the needs of identification is so much better than having to read the tiny print that is on the battery to decipher what is what. Of course not everyone who has fallen susceptible to deafness is going to be older but it is just the natural way of things.
The problems that persist with a hearing assistance device are usually misconstrued and finding the problem can be a chore all in itself. People who take the route of discount hearing aids will more times than not blame the device for the issue that is occurring.
If you are having trouble finding discount hearing aids you can simply ask your audiologist where there are bargains, search online auctions and Web sites, or just find any local retailer to help your search query. This might sound like common sense but if you have never had to look before there is no way of knowing these things.
Hearing aid batteries are more times than not going to come with the device you purchased. This can be good and bad because you will have no idea if the battery is new if it is already installed into the device.
This is something to watch for especially when you buy discount hearing aids because the reason it has been discounted might be due in part to the company you purchased it from using it as a rental or trial promotion product. If this is the case then the battery you receive might not be as new as you think it is.
Hearing aid batteries have the potential to cause you grief if you don't maintain them properly. Keeping your device powered down when you are not using it, not letting the battery be exposed to air, and always keeping it away from water damage are just a few of the ways to make sure you are getting the most out of the energy source you are relying on to power your device.
