Battery Drain Meters

Whether you are a hearing health provider in the office or a hearing aid specialist working in a lab, battery drain is an important factor for you. The amount of electronic current a hearing aid circuit is drawing can tell you a lot about whether an instrument is working properly. Many times, units are evaluated in a matter of seconds by simply reading the battery drain. You can use a drain meter to simply power an instrument, so next time you need to listen to a hearing aid why not plug it in to your drain meter and note the amount of current the hearing aid is drawing? And, knowing the actual battery drain is a great way to give your patients realistic expectations about how long their batteries should last.
