935 935  LHT65N is equipped with a 2400mAH Li-MnO2 (CR17505) battery . The battery is an un-rechargeable battery with low discharge rate targeting for up to 8~~10 years use. This type of battery is commonly used in IoT devices for long-term running, such as water meters.
936 936  
937 937  The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.
