Replacement Battery for GE 2044978-004

The KingSener SM201-6 is a lithium-ion replacement battery rated at 11.1V with selectable capacities of 39WH, 47WH or 56WH. It matches the original GE part numbers SM201-5.0-35, SM201-4.2 and DR201 for direct fit in compatible medical and power-tool equipment.

High-quality cells and black housing

Built with Grade-A Li-ion cells and an integrated protection circuit, the pack delivers the full design capacity without inflated ratings. The black enclosure mirrors the original dimensions, so installation requires no modification to the host device or mounting bracket.

Stable output for extended shifts

The chemistry provides consistent voltage under load and supports longer running time between charges. For best longevity, perform two to three full charge-discharge cycles at low current initially, avoid continuous adapter connection during use, store above 80% charge if unused for a month, and keep the pack away from heat and humidity.
