I bought this extra battery for my torch 9860 there is a little over 2 years so that the original does not wear out too quickly, I am now in bold 9900. As a result, my original battery walk wonder and one that does not work at all correctly, my laptop itself off and not even restarts, even removing / putting the battery it does not restart every time with (a problem that I do not meet with that of origin). Frankly disappointed, lost 20 euros. Seller: online Digital Electronics.
