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.

47 Make sure the positive and negative pins match.

Edwin Chen 6.1 53 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, then the battery life may be decreased.
