There's nothing worse than going about your day with a low battery, or worse, having your hearing aid battery die mid-day. Now you can accurately measure how much life is left in your hearing aid batteries with the BDM-1 Battery Drain Meter.
How It Works
The BDM-1 Battery Drain Meter works by measuring your hearing aid's milliamp draw (mA) and verifying your hearing aid manufacturer's specifications to determine how much battery life is left. It also identifies short- and open-circuit issues that may result in battery drain.
