Some of the Mictrack tracking devices will report the GPS data with backup battery voltage, when you integrate them with your cloud server and want to calculate battery voltage into percentages, this post will help you.
MT700
Rechargeable version
For the MT700/MT700-W, the battery info is as follows:
≥4.2V: 100% battery level.
≤3.4V: Low battery alert (report BLP status to server)
≤3.3V: 3%-5% (the device will shut down, on the server also can think it is 0%)
| Battery Voltage (V) | Percentage (%） |
| 4.2 | 100 |
| 4.1 | 89 |
| 4.0 | 78 |
| 3.9 | 67 |
| 3.8 | 56 |
| 3.7 | 44 |
| 3.6 | 33 |
| 3.5 | 22 |
| 3.4 | 11 |
| 3.3 | 0 |
In the original GPS data if the battery is “40” it means “4.0V”.
Non-rechageable version
For MT700-N/MT700-NW, the battery info is as follows:
≥4.5V: 100% battery level.
≤3.9V: Low battery alert (report BLP status to server)
≤3.6V: 0% (the device will shut down, on the server also can think it is 0%)
| Battery Voltage (mV) | Percentage (%） |
| ≥4500 | 100 |
| 4433 | 90 |
| 4367 | 80 |
| 4300 | 70 |
| 4233 | 60 |
| 4167 | 50 |
| 4100 | 40 |
| 4033 | 30 |
| 3967 | 20 |
| 3900 | 10 |
| 3600 | 0 |
1. This table is based on the Energizer L91
2. In the original GPS data if the battery is “4433” it means “4.433V”.
MT710
For the MT710, the battery info is as follows:
≥4.100V: 100% battery level.
≤3.400V: Low battery alert (report BLP status to server)
≤3.200V: 3%-5% (the device will shut down, on the server also can think it is 0%)
| Battery Voltage (mV) | Percentage (%） |
| 4100 | 100 |
| 4000 | 89 |
| 3900 | 78 |
| 3800 | 67 |
| 3700 | 56 |
| 3600 | 44 |
| 3500 | 33 |
| 3400 | 22 |
| 3300 | 11 |
| 3200 | 0 |
In the original GPS data if the battery is “3885” it means “3.885V”.
