This type of battery is commonly used in IoT target for long-term running, such as water meter. Dragino outdoor sensor models use this type of battery widely.

Edwin Chen 6.1 43 If we see the battery lower than 2.7v, it is time to replace battery.
44
45 Any battery with range 2.7 ~~ 3.6v can be a replacement. We recommend using Li-SOCl2 Battery. It is suggest to add SPC1520 super capacitor with the ER26500 battery,The SPC can enlarge the battery life for high frequency use (update period below 5 minutes).  If user can't find such capacitor, he can take out from old battery and add to ER26500 one.
46
47 Make sure the positive and negative pins match.

Xiaoling 23.2 54
Edwin Chen 14.1 55 The Li-SICO battery is designed for small current / long period application. 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 time to transmit LoRa or NB-IoT, then the battery life may be decreased.

168 Below factors will affect the battery life. If the battery runs out very fast unexpectedly. Please check below points:
169
Edwin Chen 12.1 170 1. Did you connect an external sensor? What is the power consumption of this sensor?
Edwin Chen 11.1 171 1. What is the (% style="color:blue" %)**uplink period**(%%) of the end node?
172 1. What is the (% style="color:blue" %)**DataRate**(%%) the sensor used to uplink?
173 1. Does the sensor sends re-transmit too oftern? See [[**this link**>>http://wiki.dragino.com/xwiki/bin/view/Main/Notes%20for%20ChirpStack/#H7.A0MultiplyUplinkinChirpStack]] for a possible issue with LoRaWAN server.
