Acerca de Panasonic NCR18500A 18500 Li-ion Cell 2,040 mAh

The NCR18500A is the 18500-format member of Panasonic's cylindrical range: 2,040 mAh typical in a 49.36 mm height instead of 65 mm. It exists for housings that were never going to take an 18650 — medical monitors, industrial terminals, precision instruments and compact instrumentation.

Why pack builders specify it

  • 49.36 mm height against 65 mm for an 18650, with 2,040 mAh still available
  • 33.5 g max, so multi-cell packs stay light in handheld equipment
  • 536 Wh/L volumetric and 204 Wh/kg gravimetric at the bare cell
  • Panasonic NNP electrode technology with HRL heat-resistance layer

Typical applications

  • Medical monitors and infusion pumps – Compact equipment where battery bay depth is fixed
  • Industrial handheld terminals – Scanners, handheld computers and test instruments
  • Security devices – Alarms, sensors and access control with a shallow battery compartment
  • Precision instruments – Metering and laboratory equipment needing a stable 3.6 V platform

Where it fits

Specify the 18500 A when the enclosure cannot take a 65 mm cell. Capacity and current are lower than an 18650 by design, so it is not a substitute for a GA or BD in a pack that has room. Panasonic does not publish a maximum continuous discharge rating for this cell — the 3.8 A figure in circulation is distributor data, so confirm against the datasheet before setting BMS limits.

Charging and pack integration

Charge CC-CV to 4.2 V (4.15 V for cycle life) within the current limits listed above and stop discharge at 2.5 V. These are unprotected industrial cells: a BMS or protection circuit is required, interconnects must be resistance or laser welded rather than soldered, and cells of different model, batch or state of charge must not be mixed in one pack. Charging below 0 °C is not permitted unless the pack implements a low-temperature charge strategy.

Certifications and documentation

UN38.3, MSDS, IEC 62133-2, CE, RoHS, REACH, PSE, KC. UN38.3 test summary, MSDS and the cell specification are available on request.

Preguntas sobre esta celda

Panasonic does not publish one for the NCR18500A. A 3.8 A (2 C) figure is widely quoted by distributors. Confirm against the current datasheet before you set pack limits.
49.36 mm versus about 65.1 mm, roughly 16 mm shorter, with the same 18.15 mm bare-cell diameter.
0.7CA, about 1,358 mA to 4.2 V with a 0.02 °C cut-off, roughly 3 hours.
