battery pins
| Pin | Name | Function |
|---|---|---|
| AL | Alarm/Alert/Allow | Used for signaling battery status (faults, over-temp, etc.) or enabling/disabling battery functions. |
| TH | Thermistor/Temperature | Connects to a thermistor for monitoring battery temperature, ensuring safe charging/discharging. |
| SC | Sense/Serial Clock | Used for voltage/current sensing or as a clock line in communication protocols (e.g., I²C/SMBus). |
| SD | Serial Data/Shutdown | Used for data communication (I²C/SMBus data line) or to control battery shutdown. |
| ID | Identification | Identifies battery type/capacity via resistor or chip, ensuring device compatibility and correct charging. |

How to Bypass Battery Pins
| Pin | Bypass Method | Notes / Risks |
|---|---|---|
| AL | Connect to ground or Vcc | Disables protection; may allow battery operation but removes fault detection. |
| TH | Replace with fixed resistor (10kΩ–100kΩ) | Simulates safe temperature; disables thermal protection. |
| SC | Connect to main battery terminal or leave open | Sensing/communication features lost. |
| SD | Tie to ground or Vcc | Keeps battery enabled; disables smart/shutdown features. |
| ID | Add resistor (e.g., 10kΩ) to ground or Vcc | Mimics correct battery type; may affect charging safety. |
⚠️ Bypassing disables safety features and can be dangerous. Use only for testing, not
