FAQ
Q: Which ThinkPad models take the SB10L84121 internal battery?
It is compatible with ThinkPad T570, T580, P51s, P52s and ThinkPad T15 G1 / G2 internal battery slots. Confirm the SB10L84121 / 01AV493 code in Lenovo Vantage or on the pack before ordering.
Q: Is this the internal or external battery?
This is the internal (built-in) battery (also called Battery 1). It works together with the removable external battery (Battery 2) to extend total runtime. It is not a replacement for the external power bridge battery.
Q: When should I replace my internal battery?
If your laptop only runs for a short time after removing the external battery, or Lenovo Vantage reports “failure” / “poor health” for Battery 1, it is time to replace the SB10L84121.
Q: What warranty is included?
A 1-year warranty applies, with high-quality cells and BMS protection for safe charging.
