Maximum energy for demanding applications

The PANASONIC NCR18650B battery is the first choice for producing high-performance battery packs. Its high capacity makes it the ideal energy source for long-range pedelec and e-bike batteries, professional power tools, premium LED torches, power banks and medical devices. Wherever maximum runtime is required with low weight and volume, this cell offers the optimum solution.

Advanced lithium-ion technology

PANASONIC's lithium-ion technology stands for high nominal voltage and excellent energy density. The NCR chemistry (nickel-cobalt-aluminium) is characterised by a particularly high capacity and good cycle stability. The cell is designed for high continuous loads and provides a stable voltage curve during discharge, which optimises the efficiency and performance of the end device.

Developed for industrial assembly

As a highly specialised unprotected industrial cell, the NCR18650B is intended for professional further processing. Its standardised dimensions and flat positive terminal (Flat Top) ensure reliable welding into multi-cell battery packs. PANASONIC's high batch consistency enables the assembly of large, reliable battery systems with homogenous performance.

FAQs about the PANASONIC Li-Ion Battery NCR18650B

What does "unprotected" industrial cell mean?

"Unprotected" means that the individual cell does not have an integrated electronic protection circuit (PCB/BMS) that protects it from deep discharge, overcharge or short circuit. It is intended exclusively for installation in battery packs where external protection electronics (BMS) take over these safety functions for the entire pack. Direct operation as a single cell is not safe and not intended.

Who is this battery suitable for?

This cell is intended exclusively for professionals and commercial customers who have experience in handling and assembling Li-Ion batteries and are able to implement the necessary protective measures (BMS/PCM). It is not a battery for direct use by end consumers.

How is this cell charged?

Lithium-ion cells require a special charging method (CC-CV: constant current, then constant voltage). Charging must only be carried out with a suitable Li-Ion charger or charging circuit which precisely maintains the final charging voltage of 4.2 V. Incorrect charging can destroy the cell and poses a safety risk.

How should this battery be disposed of?

Batteries must not be disposed of with household waste. As an industrial waste battery, it is subject to the provisions of the Battery Act. Please take the used battery to the appropriate industrial or municipal collection points (e.g. GRS Batterien) to ensure proper and environmentally friendly recycling.
