I am very happy with this product,awsum product in cheaper price. Giving charging more than 3 hours.
for lenovo any series this battery will be fine.

Worst product ever :'( I thought it was a good product as it gave 2.5 hours back up a the start..This battery would suddenly die out unlike most batteries, which put computer to sleep or hibernate..It did not even last three months....The company needs to build good batteries and release them only after testing...
