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. 608 + 609 + 610 + 611 +=== 2.12.4 Replace the battery === 612 + 613 + 614 +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). 615 + 616 + 617 + 567 567 = 3.
