	83	+== Battery Type ==
	84	+
	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.

	98	+== Replace Battery ==
	99	+
	100	+Any battery with a range 2.45 ~~ 3.6v can be a replacement. We recommend using Li-SOCl2 Battery.
	101	+
	102	+And make sure the positive and negative pins match.

	108	+Dragino Battery-powered products are all runs in Low Power mode. We have an updated battery calculator which base on the measurement of the real device. User can use this calculator to check the battery life and calculate the battery life if want to use different transmit intervals.
	109	+
	110	+Instruction to use as below:
	111	+
	112	+
	113	+**Step 1**: Downlink the up-to-date DRAGINO_Battery_Life_Prediction_Table.xlsx from: [[https:~~/~~/www.dragino.com/downloads/index.pHp?dir=LoRa_End_Node/Battery_Analyze/>>url:https://www.dragino.com/downloads/index.php?dir=LoRa_End_Node/Battery_Analyze/]]
	114	+
	115	+
	116	+**Step 2**: Open it and choose

	127	+
	128	+And the Life expectation in difference case will be shown on the right.

	146	+=== 4.3.1 ​Battery Note ===
	147	+
	148	+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.
	149	+
	150	+=== ​4.3.2 Replace the battery ===
	151	+
	152	+You can change the battery in the LLMS01.The type of battery is not limited as long as the output is between 3v to 3.6v. On the main board, there is a diode (D1) between the battery and the main circuit. If you need to use a battery with less than 3.3v, please remove the D1 and shortcut the two pads of it so there won’t be voltage drop between battery and main board.
	153	+
	154	+The default battery pack of LLMS01 includes a ER26500 plus super capacitor. If user can’t find this pack locally, they can find ER26500 or equivalence, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes)
