MDHearingAid Battery Tester for Hearing Aid (Battery Tester Only)

The battery tester is useless. My hearing aid was warning me that the batteries were low. These showed that they were full. Tried the placing the batteries on for a few seconds as advised by others and they do show the percentage going down. However, placed brand new batteries and tried the same. Percentage is 100% when first testing, then goes down in percentage regardless on if they are new or depleted.Cleaning tools were good, so 2 stars.Update: Found a battery that was completely depleted and the tester showed the same. You need to test the battery as soon as they are removed from the hearing aid or they will recharge and incorrectly appear to show full when testing. The cleaning tools more than pays for the cost, so changing to 4 stars.

Great for cleaning out hard to reach spots in IEM. While it's intended for hearing aids, musicians will love these for their in ear monitors.

We had a dead battery but the indicator was showing it had a lot of juice left- yet it would power on the hearing aid.

Works as expected clearing obstructions and keeping your hearing device functioning.
