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.
563 563  
458 +Instruction to use as below:
564 564  
565 -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/]]
566 566  
567 -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**
574 574  
575 -== 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.
576 576  
476 +**2.9.4  Replace the battery**
577 577  
578 -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).
