85		-GroPoint Air is equipped with a [[8500mAH ER26500 Li-SOCI2 battery>>url:https://www.dragino.com/downloads/index.php?dir=datasheet/Battery/ER26500/]]. The battery is an un-rechargeable battery with a low discharge rate targeting more than 5 years use. This type of battery is commonly used in IoT targets for long-term running, such as water meters.
86		-
87		-The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

138		-=== ​Battery Note ===
139		-
140		-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.
141		-
142		-
143		-=== Replace the battery ===
144		-
145		-You can change the battery in GroPoint Air. The type of battery is not limited as long as the output is between 3v to 3.6v.
146		-
147		-The default battery pack of GroPoint Air includes a ER26500 plus supercapacitor. If users can’t find this pack locally, they can find ER26500 or equivalence, which will also work in most cases. The SPC can enlarge the battery life for high-frequency use (update period below 5 minutes)
