User Manual for LoRaWAN End Nodes - CPL01 LoRaWAN Outdoor Pulse/Contact Sensor
4. Battery & how to replace
4.1 Battery Info
8500mAH ER18505 Li-SOCI2 battery
. The battery is an un-rechargeable battery with a
low discharge rate targeting 8~10 years of use. This type of battery is commonly used in IoT targets for long-term
running, such as water meters.
The battery-related documents are as below:
•
,
•
Lithium-Thionyl Chloride Battery datasheet
•
Lithium-ion Battery-Capacitor datasheet
The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery
performance.
Minimum Working Voltage for the CPL01:
CPL01: 2.45v ~ 3.6v
4.1.1 Battery Note
The Li-SICO battery is designed for small current / long period applications. It is not good to use a high current,
short period transmit method. The recommended minimum period for use of this battery is 5 minutes. If you use a
shorter period to transmit LoRa, then the battery life may be decreased.
4.2 Replace Battery
Any battery with a range of 2.45 ~ 3.6v can be a replacement. We recommend using Li-SOCl2 Battery.
And make sure the positive and negative pins match.
