6.1 | 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. | ||

| |
7.2 | 53 | |
| |
14.1 | 54 | 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. |

14.1 | 57 | === 1.4.2 Can i replace battery with SPC1520? === |
| 58 | |||
| |
15.1 | 59 | User can replace the battery with ER26500 without SPC1520, This will work. But will have reduced performance for example |
| |
14.1 | 60 | |
| 61 | 1) Shorter Battery Life. | ||
| 62 | |||
| 63 | 2) Not enough to provide enough current burst in low temperature. | ||

| 121 | Below factors will affect the battery life. If the battery runs out very fast unexpectedly. Please check below points: | ||
| 122 | |||
| |
12.1 | 123 | 1. Did you connect an external sensor? What is the power consumption of this sensor? |
| |
11.1 | 124 | 1. What is the (% style="color:blue" %)**uplink period**(%%) of the end node? |
| 125 | 1. What is the (% style="color:blue" %)**DataRate**(%%) the sensor used to uplink? | ||
| 126 | 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. | ||
