• 【Battery Capacity】Each 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

It offers an economical and environmentally conscious solution for powering your traditional hearing aids
• 【Durability】The 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.

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
