Sanyo NCR20700B 4000mAh 15A Battery

Product Overview

The Sanyo NCR20700B is a high-capacity 20700 rechargeable cell. Its 4000mAh capacity is much higher than the Hohm Tech cells listed on your store (about 3000 to 3300mAh), while its 15A continuous discharge rating is moderate. That makes it a better fit for long run time in devices that do not draw very high current, rather than for very high-power mods. It is a well-known cell model, widely used in flashlights, power tools, and some vape devices.

(Confirm the exact details before publishing: whether this is a genuine Sanyo/Panasonic-made cell or a re-wrapped or counterfeit one, which is very common for this model, whether the 4000mAh and 15A figures match the manufacturer’s datasheet, whether it is sold as a single cell or a pack, whether it is a bare cell or in a branded wrap, flat-top or button-top, and whether a case is included. This is a general-purpose cell and is not specifically a vape battery, so check that your devices’ current draw stays within 15A.)

Key Features

• 4000mAh capacity: Very long run time per charge. (Confirm against the datasheet.)
• 15A continuous discharge: Suitable for moderate-power devices. (Confirm against the datasheet.)

• Rechargeable: Reusable with a suitable lithium-ion charger that supports 20700 cells.
• Well-known cell model: Widely used across many device types. (Mention only if your supply is genuine.)
• Top type: (Confirm flat-top or button-top, and device fit.)
• Included items: (Add whether a plastic case is included.)
• Pack size: (Confirm single cell or multi-pack.)

How to Use

1. Check your age and local laws. For adults 21+ only.
2. Read your device manual to confirm it takes 20700 cells and check its current limits.
3. Inspect the wrap before each use. Do not use a cell with any tear, dent, or damage.
4. Insert the battery following the polarity marks (+ and -).
5. Use matched cells in multi-battery devices: same brand, model, age, and charge level.
6. Charge with a proper lithium-ion charger that supports 20700 cells, and never leave it charging unattended.
7. Carry and store in a plastic case, never loose in a pocket or bag with keys or coins.
8. Stay within the rating: make sure your device’s draw does not exceed 15A continuous.
9. Replace the cell if performance drops noticeably or it gets very hot.

Stop use immediately if the battery gets hot, swells, leaks, or smells unusual.

Why Choose It?

• Very high capacity: Longer use between charges.
• Moderate current rating: A good match for lower to mid-power devices.
• 20700 format: A popular middle size.
• Rechargeable: Better value than disposable cells over time.
• Easy to compare: Fits alongside your other battery listings.
