FAQ
Q: Is the actual capacity 3450 mAh or 3500 mAh?
A: Panasonic specifies the typical capacity as 3450 mAh (minimum 3350 mAh). Many retailers label it as 3500 mAh for simplicity. You can expect approximately 3400–3500 mAh capacity under normal charging conditions, with negligible impact on real-world runtime.
Q: Can I use these batteries for vaping or high-power mechanical mods?
A: No. Vaping devices with sub-ohm coils often draw 15–30 A, which exceeds the 10 A continuous rating. Using these cells for vaping can cause dangerous overheating, severe voltage sag, and reduced lifespan. For vaping, please choose high-drain cells like Sony VTC6 or Samsung 30Q (20A+).
Q: What’s the difference between Flat Top and Button Top, and how do I choose?
A: Flat Tops are standard for most flashlights and battery holders with spring contacts. Button Tops have a raised positive nipple, which is required for some devices that lack a spring or need physical reverse-polarity protection. The electrical performance is identical; button tops have a negligible increase in internal resistance. Check your device’s battery orientation and contact type before ordering.
Q: Do I need a protection circuit board when building a pack?
A: Absolutely. When connecting multiple cells in series or parallel, always use a BMS/PCM rated for at least 10 A to protect against overcharge, over-discharge, and short circuits. Unprotected series connections can lead to unbalanced cells, fire, or battery failure.
Q: How should I store and maintain these batteries?
A: Store in a cool, dry place at approximately 3.6–3.7 V (40–50% charge). Do not leave fully discharged or fully charged for extended periods. Charge before first use, and never discharge below 2.5 V. Always use a quality Li-ion charger compatible with 18650 cells.
Q: Can I replace my old 18650 batteries directly with these?
A: In most cases, yes, provided the device’s current draw does not exceed 10 A and the cell top type matches. Check your device manual for any size or contact requirements. If you are unsure, contact the device manufacturer.
