From Gamebuino Wiki
| Level | Voltage | Status | Usual duration |
| 0 | <3500 mV | Auto-shutdown | |
| 1 | 3500-3550 mV | Critical | 30 minutes |
| 2 | 3550-3700 mV | Empty | 2 hours |
| 3 | 3700-3900 mV | Half | 8 hours |
| 4 | >3900 mV | Full | 8 hours |
Here is a typical voltage evolution during battery discharge (with no sound and no backlight):
