Replacement battery specifications

The KingSener M5070A is a 10.8V lithium-polymer replacement battery rated at 5200mAh and 56.16Wh. It uses Li-ion 18650 cells and a black housing that matches the original dimensions. The part carries model references NF2040HD, NF2040XD, NF2040DY, NF2040AG24, NF2040QE34, NF2040SM24, TY 3CGR18650D-2, N9330B-BCG, N9330B-BAT, 72R6893, N9910X-870, SM206 and KSE2040-2. It is supplied new and ready to install.

Compatibility and limits

This unit suits owners of laptops that originally shipped with the listed NF2040-series batteries and need a direct swap with no case modification. It will not help buyers who require a different voltage, a higher capacity than 5200mAh, or a form factor that differs from the original black pack. Verify the exact model number and physical appearance before purchase.

Deciding specification

The critical figure is the 10.8V 5200mAh rating; only devices designed for that voltage and capacity should use this battery. Using it in a system expecting a different voltage risks damage and will not deliver the intended run time.

Questions about this item

Which original battery part numbers does the KingSener M5070A replace?

It replaces NF2040HD, NF2040XD, NF2040DY, NF2040AG24, NF2040QE34, NF2040SM24, KSE2040-2, TY 3CGR18650D-2, N9330B-BCG, N9330B-BAT, 72R6893, N9910X-870 and SM206.

Will the 10.8 V 5200 mAh capacity match the runtime of my original battery?

The 56.16 Wh rating equals or exceeds the original design capacity, so runtime should be at least the same as a new OEM pack.

How can I confirm the battery is working correctly after the first few charge cycles?

Fully charge and discharge it two or three times; the pack should then hold a full charge without unexpected shutdowns.
