12-cell 14.4V Li-ion Replacement Battery

The KingSener M5070A is a 12-cell lithium-ion battery rated at 14.4V and 6.75Ah. It serves as a direct replacement for Inspired Energy NL2054 modules used in medical and portable equipment. The pack is built with high-quality cells and a matched PCB to deliver the full design capacity without inflation. It is intended for technicians and operators who need a dependable power source for compatible devices.

Voltage and Chemistry Constraints

The 14.4V output is fixed by the 12-cell series arrangement and Li-ion chemistry, so it only suits equipment designed for that exact nominal voltage. Using the pack with systems expecting a different voltage risks damage and will not function. The battery requires a compatible charger that follows the correct Li-ion charge profile; continuous connection to an unsuitable adapter can degrade the cells. No other interface or communication protocol is specified.

6.75Ah Capacity and Operational Limits

At 6.75Ah the battery provides extended runtime for supported Inspired Energy devices, reducing the frequency of recharge cycles during field use. Runtime scales with the load drawn by the host equipment; high-drain applications will exhaust the charge sooner. For storage, the pack should be kept above 80% charge and topped up at least once a month to preserve health. It is not suitable for devices requiring a different form factor, voltage, or higher capacity than 6.75Ah.

Questions about this item

How do I know this 12-cell 14.4V 6.75Ah pack is the right replacement for my device?

Match the original battery model or part number to NL2054 and confirm the physical dimensions against the product photos; the pack is built to the same size as the original unit.

What does the 6.75Ah rating mean for daily runtime in a medical device?

The 6.75Ah capacity at 14.4V delivers a high energy reserve, so compatible equipment runs longer between charges during continuous monitoring or transport.

What interface does the NL2054 use and what does it limit?

The battery connects through the proprietary Inspired Energy interface, which governs communication, charging control and safe power delivery to the host device.
