The SMBus pins (Clock and Data) will typically show a logic-level voltage (often 3.3V ) when the battery is active or connected to a charger.
Often a "detect" pin that must be grounded to activate voltage. NC / Reserved Frequently unused or reserved for manufacturer testing. Positive (V+) Main positive power terminal (typically 10.8V–11.1V). Positive (V+) Parallel positive power terminal for high current. Technical Specifications 10.8V to 11.1V. Cell Configuration: 6-cell Lithium-Ion (3S2P — 3 series, 2 parallel). Ranges from 4400mAh to 5200mAh depending on the specific model. Communication: SMBus (System Management Bus) protocol, often managed by a or similar Texas Instruments impedance tracking gauge. Amazon.com Critical Troubleshooting Notes Safety Lock:

If you are trying to read the battery telemetry using an Arduino, Raspberry Pi, or a specialized battery analyzer (like the EV2300/EV2400), you cannot simply apply voltage to the positive and negative terminals.
Be extremely careful not to bridge the Positive (+) and Ground (-) pins, as this will trigger the battery’s internal protection circuit (BMS) or damage the pack permanently.

Secure the battery flat on an anti-static mat. Locate Pin 1 (far left) and Pin 6/Pin 7 (far right).
The same pinout is found in:
Pin layout (left-to-right when the battery contact side faces you, contacts exposed upward): Positive (V+) Main positive power terminal (typically 10
The battery operates at a nominal voltage of 10.8V, which corresponds to three Li-ion cells connected in series (3 × 3.6V = 10.8V). Some versions are rated at 11.1V, reflecting slight variations in cell chemistry, and this voltage range is well within the acceptable input tolerance of most HP laptop charging circuits.
To trick the internal BMS into thinking it has been inserted into an HP laptop, take a small jumper wire or a metal paperclip. Connect one end to and the other end to Pin 6 or Pin 7 (GND) . Step 3: Measure the Output Voltage
when looking at the battery with the connector facing you and the label side up. Description Ground (GND)
Use a multimeter to find the outer pins. The pair showing roughly 10.8V - 11.1V is the Positive (+), while the opposite end with zero resistance to the case is Ground (-).
