FAQ: Frequently Asked Questions 

ThinkPad X1 Carbon Gen 3 Battery (00HW002 / 00HW003) — FAQ
Is this battery compatible with my laptop?
Yes — it’s designed for ThinkPad X1 Carbon Gen 3 (2015), commonly the 20BS / 20BT models. It replaces FRU/ASM codes 00HW002 / 00HW003 (also seen as SB10F46440 / SB10F46441 on some labels).
What are the capacity and voltage?
51 Wh (4-cell) at 15.2 V nominal. Some listings quote 50–51 Wh; both reflect the same 4-cell pack class.
Will it fit Gen 2 or Gen 4 X1 Carbon?
No — battery shapes/FRUs differ between generations. This pack is for Gen 3. Check your exact model (e.g., 20BS/20BT) before ordering.
Is it an original Lenovo battery?
Memox lists a compatible replacement for the Lenovo FRU. It’s built to the same form factor and connector spec and is a direct fit for Gen 3 X1 Carbon.
Do I need to disable the built-in battery before replacement?
Yes — Lenovo recommends disabling the internal battery in BIOS/Lenovo service mode (and disconnecting AC) before removal. Follow Lenovo’s HMM/replacement video for Gen 3.
Any tips for a successful install?
Power down, disable the built-in battery, remove base cover, disconnect the old pack, fit the new one, reconnect, reassemble, then charge to 100% and let it rest on AC for 2–3 hours.
Will 14.8 V batteries work?
Some aftermarket listings note 14.8 V and 15.2 V are cross-listed for this model family. Use the correct Gen-3 FRU (00HW002/00HW003) to ensure fit and connector alignment.
How long will the battery last per charge?
Runtime depends on screen brightness, CPU load, age of the laptop, and background apps. Expect normal day-to-day use to vary widely; heavy tasks will reduce runtime.
Does it need calibration?
Optional but helpful: after a few cycles, do one full charge to 100%, then discharge to ~10–15%, and recharge. This helps the gauge learn the new pack.
What’s the warranty?
Typically 12 months on replacement batteries (see product page for exact Memox terms).
Which FRU/part numbers does this replace?
00HW002, 00HW003; often cross-referenced as SB10F46440 / SB10F46441.
