7680 mAh Backup Battery for Oxygen Treatment Machine

The backup battery for this oxygen concentrator is exactly the same as the original battery, with a capacity of 7680mAh and the same adaptation standards. You can use it right away. The single-battery life is 2-6 hours, and when used with the original battery, the life is doubled to 4-12 hours, which can easily cover scenarios such as the elderly going out for a walk, plateau hiking, and long-distance self-driving, saying goodbye to battery anxiety. It can be charged and discharged more than 500 times in normal use (can be used for 2-3 years), and it has overcharge and over-discharge protection, and is stable even in low temperature and bumpy conditions. It is not only a necessary guarantee for outdoor oxygen therapy, but also an emergency backup at home.
