510 +The NMDS200 battery is a combination of an 8500mAh Li/SOCI2 Battery and a Super Capacitor. The battery is non-rechargeable battery type with a low discharge rate (<2% per year). This type of battery is commonly used in IoT devices such as water meter.

512 +The battery is designed to last for several years depends on the actual use environment and update interval.

525 +=== 2.11.2  Power consumption Analyze ===
526 +
527 +
528 +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.
529 +
530 +Instruction to use as below:
531 +
532 +(% style="color:blue" %)**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/]]
533 +
534 +(% style="color:blue" %)**Step 2: **(%%) Open it and choose
535 +
536 +* Product Model
537 +
538 +* Uplink Interval
539 +
540 +* Working Mode
541 +
542 +And the Life expectation in difference case will be shown on the right.

546 +
547 +=== 2.11.3  ​Battery Note ===
548 +
549 +
550 +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.
551 +
552 +
553 +=== 2.11.4  Replace the battery ===
554 +
555 +
556 +The default battery pack of NMDS200 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).
