Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
While leakage is rare, it may still occur if the battery is used incorrectly. Leakage is usually caused by leaving the battery in an unused device or short-circuiting.
This is a guarantee that no mercury is added during production.
You’re always allowed to board the plane with your hearing aid batteries in the device. For regulations on bringing spare hearing aid batteries, please consider contacting your airline.
Always insert batteries with the poles in the correct direction. Not doing so will lead to a short circuit.
Panasonic strongly advocates not attempting to charge primary batteries such as alkaline, zinc carbon, or lithium, using Ni-MH chargers. Alkaline batteries are not designed for recharging, and doing so could cause leakage and in the worst case lead to the batteries exploding.
You’re always allowed to board the plane with your hearing aid batteries in the device. For regulations on bringing spare hearing aid batteries, please consider contacting your airline.
Panasonic hearing aid batteries, or zinc air batteries, need air to work. As soon as you pull off the seal, air will flow into the battery, making it able to release energy. Be sure to let the battery breathe for a few minutes before inserting it into your device.
Typically for an alkaline battery is a gradually decreasing voltage when it discharges, which means that for some appliances, which need a high base voltage to operate, the appliance stops working even while the battery has still a bit of energy left.
The memory effect is an occasional defect, which occurs in Ni-Cd and Ni-MH rechargeable batteries, where the maximum battery voltage decreases even though the original power of the battery remains the same.
Batteries are chemical products which internally undergo certain chemical processes over time. Due to this process some batteries slightly discharge during storage.
