By perusing an old tabook, I figured that I'd probably want the biggest one, that is 43R9255, 9-cell one.
1. Where should I buy them online and how much do they normally cost?
2. How do I recognize an original battery from a third-party one? (original is more expensive and supposed to be better, right?)
3. Should I expect the replacement battery I buy online to be as good as new one was back in the day, or would they be old and dead? In which case, I would rather get a dead one and upgrade it at a local company: there's a local company fixes old batteries for laptops and other battery-operating equipment; they are in business for 10 years already, they are using new high-quality cells and appropriate equipment (spot welding, nickel tape) and give 1 year warranty on their work.
4. Do X200 and X200s use the same batteries? If you got either, please tell me its stated voltage and capacity.
To the best of my understanding, the options for both X200 and X200s are:
- ThinkPad Battery 47 (4-cell) 43R9253
- ThinkPad Battery 47+ (6-cell) 43R9254
- ThinkPad Battery 47++ (9-cell) 43R9255
