1642 = 5. Battery & How to replace =
1643
1644 == 5.1 Battery Type ==
1645
1646 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.
1647
1648
1649 The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.
1650 [[image:image-20220515075034-1.png||_mstalt="428961" _mstvisible="4" height="208" width="644"]]
1651
1652 The minimum Working Voltage for the LHT65N is ~~ 2.5v. When battery is lower than 2.6v, it is time to change the battery.
1653
1654
1655 == 5.2 Replace Battery ==
1656
1657 LHT65N has two screws on the back, Unscrew them, and changing the battery inside is ok. The battery is a general CR17450 battery. Any brand should be ok.
