1 out of 5 eggsNowhere close to Lenovo quality

Pros: - Low cost
- Only available battery option for T61p 14" laptops

Cons: - Contains 2.2Ah cells rather than 2.6Ah cells like Lenovo original
- Isn't complete plastic clamshell, has stickers to cover battery terminals
- Plastic smells like phenolic rather than ABS like original Lenovo part (ie, smells toxic)

Other Thoughts: This is clearly a low quality knockoff of the original Lenovo part. If possible, I'd shop elsewhere for an authentic part.

I'm an electrical engineer and I don't understand how this thing could possibly pass UN testing for shipping. It also doesn't carry any safety certification labels.
