| 43 | If we see the battery lower than 2.7v, it is time to replace battery. | ||
| 44 | |||
| 45 | Any battery with range 2.7 ~~ 3.6v can be a replacement. We recommend using Li-SOCl2 Battery. It is suggest to add SPC1520 super capacitor with the ER26500 battery,The SPC can enlarge the battery life for high frequency use (update period below 5 minutes). If user can't find such capacitor, he can take out from old battery and add to ER26500 one. | ||
| 46 | |||
| 47 | Make sure the positive and negative pins match. | ||

| 51 | |||
| 52 | === 1.4.1 Can i use send uplink in short period? === | ||
| 53 | |||
| 54 | |||
| 55 | 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 or NB-IoT, then the battery life may be decreased. | ||
| 56 | |||
| 57 | |||
| 58 | === 1.4.2 Can i replace battery with SPC1520? === | ||
| 59 | |||
| 60 | |||
| 61 | User can replace the battery with ER26500 without SPC1520, This will work. But will have reduced performance for example | ||
| 62 | |||
| 63 | 1) Shorter Battery Life. | ||
| 64 | |||
| 65 | 2) Not enough to provide enough current burst in low temperature. | ||

| 158 | |||
| 159 | Below factors will affect the battery life. If the battery runs out very fast unexpectedly. Please check below points: | ||
| 160 | |||
| 161 | 1. Did you connect an external sensor? What is the power consumption of this sensor? | ||
| 162 | 1. What is the (% style="color:blue" %)**uplink period**(%%) of the end node? | ||
| 163 | 1. What is the (% style="color:blue" %)**DataRate**(%%) the sensor used to uplink? | ||
| 164 | 1. Does the sensor sends re-transmit too oftern? See [[**this link**>>http://wiki.dragino.com/xwiki/bin/view/Main/Notes%20for%20ChirpStack/#H7.A0MultiplyUplinkinChirpStack]] for a possible issue with LoRaWAN server. | ||
