38.2	805	PS-LB is equipped with a [[8500mAH ER26500 Li-SOCI2 battery>>https://www.dropbox.com/sh/w9l2oa3ytpculph/AAAPtt-apH4lYfCj-2Y6lHvQa?dl=0]]. The battery is un-rechargeable battery with low discharge rate targeting for 8~~10 years use. This type of battery is commonly used in IoT target for long-term running, such as water meter.
6.2	806
	807	The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

6.2	818
38.2	819
6.2	820	Any battery with range 2.45 ~~ 3.6v can be a replacement. We recommend to use Li-SOCl2 Battery.
	821
	822	And make sure the positive and negative pins match.

40.4	854	=== 4.3.1 Battery Note ===
6.2	855
	856
	857	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.
	858
	859
40.4	860	=== 4.3.2 Replace the battery ===
6.2	861
	862
40.4	863	You can change the battery in the PS-LB.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.
6.2	864
40.4	865	The default battery pack of PS-LB 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)
