FAQ
Q: How can I confirm this is an authentic LG HG2?
A: You can verify authenticity by: 1) Checking the QR code on the wrapper; 2) Measuring internal resistance (genuine HG2 is typically 15-20mOhm). We label this product as "Authentic & Tested," meaning we have performed professional screening on these cells.
Q: What is the difference between LG HG2 and Samsung 30Q?
A: LG HG2 (Chocolate) and Samsung 30Q are both famous 3000mAh / 20A cells. The HG2 generally offers slightly lower internal resistance and better heat management under high loads. The 30Q typically excels in cycle life. Both are top-tier. This listing is for the HG2.
Q: Can I use this battery in a standard flashlight?
A: Not recommended. Standard flashlights (<500 lumens) often draw only 0.5A-2A. Using a 20A HG2 is overkill and cost-inefficient. For standard lights, consider 2600mAh or 3500mAh cells.
Q: Does this battery have a protection circuit?
A: No. This is a bare, unprotected cell. Use with devices/chargers that have built-in over-charge and over-discharge protection.
Q: Can I use this battery in my power drill?
A: Yes, but primarily for small brushless drills or screwdrivers where the voltage matches (often in a battery pack). For single-cell use, ensure your device accepts a 3.7V flat-top bare cell.
