FOCUSTEC M5Y1K 40Wh 14.8V laptop battery 5566 3552

What this battery replaces

This FOCUSTEC M5Y1K replaces the original Dell M5Y1K and dozens of matching part numbers such as GXVJ3, HD4J0, K185W, VN3N0, 451-BBMG, 453-BBBP, WKRJ2, P51F, P47F, P63F, P64G and P52F. It matches the factory 14.8V 40Wh 2600mAh rating so the laptop sees the same voltage and capacity as the pack it shipped with. The jump is worth it when the old pack no longer holds a usable charge or reports a permanent failure code.
