Eight-cell pack for portable power

This pack contains eight KingSener NCR18650B lithium-ion cells rated at 3.6V and 3400mAh each. They are designed as direct replacements for Panasonic cells in laptop battery packs or custom portable projects. Builders and technicians who need matched cells for series or parallel configurations will find the consistent capacity useful. The cells arrive new and ready for assembly into larger packs.

Cylindrical 18.5 mm by 65.3 mm format fits

Each cell measures 18.5 mm in diameter and 65.3 mm in height, matching the common 18650 form factor. The flat-top terminals suit soldered nickel-strip connections or spring-loaded holders without modification. No integrated protection circuit is present, so the pack builder must add a suitable battery management system. Physical dimensions match original Panasonic cells for drop-in compatibility.

Rated for standard CC-CV charging at 1625 mA

The manufacturer specifies a constant-current constant-voltage charge at 1625 mA to 4.20V, completing in roughly 4.0 hours. Minimum capacity is listed at 3250mAh, giving a predictable floor for runtime calculations. Cells should not be left on charge indefinitely and must be stored above 80% charge if unused for long periods. Operating or storage in hot or humid conditions will degrade cycle life.

Questions about this item

What voltage does the 3.6V NCR18650B cell reach at full charge?

The CC-CV charging profile terminates at 4.20V after roughly 4.0 hours at a standard 1625mA current.

Will an 18.5mm diameter by 65.3mm height cell fit my existing 18650 holder?

Yes, those are the standard 18650 dimensions so the cell matches common battery compartments and sleds.

How should I perform the initial charge-discharge cycles the supplier recommends?

Fully charge and discharge the cell at low current two or three times to condition the capacity before regular use.
