Main Highlights

Battery CapacityEach button battery has a capacity of 15mAh. When fully charged, it provides 4 hours of battery life for Bluetooth hearing aids and 8-10 hours for non-Bluetooth hearing aids. Using our charger, a full charge takes only 4 hours. The compact size of 312 rechargeable battery has a relatively small capacity for safety reasons. Therefore, it is not suitable for higher-drain Bluetooth hearing aids. We also strongly recommend having multiple batteries on hand for replacement
Usage Instructions Connect to the Type-C charging port; the two indicator lights on the front of the charging case will illuminate. Place the battery into the charging slot with the positive terminal facing forward and the negative terminal facing backward. The indicator lights will display red, indicating charging has begun. Once charging is complete, the indicator lights will turn green. Note: If the indicator lights remain green continuously, it indicates poor contact and requires adjustment
Economical and Eco-FriendlyThis product transforms disposable batteries into rechargeable ones, effectively reducing the cost of repeatedly purchasing single-use batteries while alleviating recycling burdens. It offers an economical and environmentally conscious solution for powering your traditional hearing aids
DurabilityThe charging case is crafted from ABS material, offering robust durability and resistance to wear. Compact and lightweight, it is convenient for on-the-go use. The battery utilizes premium silver-zinc material, ensuring excellent conductivity and resistance to damage or leakage. Safe and reliable, it guarantees long-term, repeated use without compromising device functionality
Important Notes 1) Always use a compatible charger from the same brand to charge the battery. 2) Ensure the battery surface is clean and dry before each charge, especially avoiding sweat residue to prevent corrosion and extend battery life. 3) Never reverse the positive and negative terminals

Important NoticeDue to the rechargeable feature of this battery, to avoid too long charging times and ensure safety, it cannot provide the same extended runtime as disposable batteries. If you are concerned about runtime, please do not purchase this product, as it may bring you a poor user experience!
15mAh Battery CapacityThis 312 battery has a capacity of 15mAh. After a full charge lasting up to 8 hours, it can power a standard hearing aid for approximately 810 hours. Please note that due to the extremely high power consumption of Bluetooth hearing aids, this battery can only power a Bluetooth hearing aid for approximately 4 hours! The actual usage time may vary depending on the power consumption and usage patterns of different hearing aids
How to UsePlace the battery with the positive terminal forward and negative backward into the charging slot. Connect the Type-C charging cable both indicator lights will illuminate to show charging starting. Due to possible poor contact between the battery and the slot, the lights may appear green initially. If one side isnt working, its usually also a contact issue. Gently rotate the battery on that side to the correct angle to ensure proper connection, and charging will resume normally
User-Friendly DesignThis product features a clever design. The box-shaped device not only perfectly stores button batteries, effectively preventing small batteries from getting lost, but also makes charging operations extremely convenient unlike other button battery chargers that require precise handling. this charger is made of durable ABS material, sturdy and impact-resistant, compact and lightweight, making it easy to carry and charge your hearing aid batteries anytime, anywhere!
Economical & Eco-FriendlyA single rechargeable battery can be recharged 300500 times. Using rechargeable hearing aid batteries can reduce the number of discarded disposable batteries by approximately 50200 per year, not only saving costs associated with repeatedly purchasing disposable batteries but also reducing environmental pollution
Charging MattersBefore charging, please keep the battery surface clean and dry. Especially during the summer, when there is more sweat on fingers, if charge the battery while it is covered in sweat for an extended period of time, it may cause corrosion inside the battery, rendering it unusable!
