Check original battery model and connector layout

Confirm the original battery carries the XSBT420AS XSBT420UK XSBT420EU part numbers and compare the physical appearance with product photos. Verify the connector position matches exactly before ordering. The pack is the same size as the original so no adaptation is required. Units that use a different part number will not fit.

Li-ion cells with integrated protection circuit

Black plastic housing encloses cells made in China with a built-in PCB for overcharge and short-circuit protection. To maintain capacity, fully charge and discharge from low current two or three times initially. Avoid leaving the charger connected during use and store above 80% charge if removed for a month. Do not disassemble crush puncture or expose to fire or water.
