456 +Dragino battery powered product are all runs in Low Power mode. We have an update 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 interval.
562 562  
458 +Instruction to use as below:
563 563  
564 -Users can directly access the AT command set of the NB-IoT module.
460 +**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/]]
565 565  
566 -The AT Command set can refer the BC35-G NB-IoT Module AT Command: [[https:~~/~~/www.dragino.com/downloads/index.php?dir=datasheet/other_vendors/BC35-G/>>url:https://www.dragino.com/downloads/index.php?dir=datasheet/other_vendors/BC35-G/]]

472 +**2.9.3  ​Battery Note**
573 573  
574 -== 4.1  Access AT Commands ==
474 +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.
575 575  
476 +**2.9.4  Replace the battery**
576 576  
577 -See this link for detail:  [[https:~~/~~/www.dropbox.com/sh/351dwor6joz8nwh/AADn1BQaAAxLF_QMyU8NkW47a?dl=0>>url:https://www.dropbox.com/sh/351dwor6joz8nwh/AADn1BQaAAxLF_QMyU8NkW47a?dl=0]]
478 +The default battery pack of NLMS01 includes a ER26500 plus super capacitor. If user can't find this pack locally, they can find ER26500 or equivalence without the SPC1520 capacitor, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes).
