I bought this battery this summer, so I step back to have an objective opinion on it. I must say I am very satisfied, it is perfectly consistent with the description. There is no major problem, the battery goes and come out of the machine without forcing and fits in the slot if you remove the back cover. In terms of autonomy, it stands as the original battery, a day for me to have a fairly intensive use, I have generally 30-40% at the end of the day, which is still enough to take a few hours. Restricted use, it takes 2 or 3 days, which is quite satisfactory in my opinion. So a positive assessment regarding the battery. However, the package if we can call it that, is really short of what is needed. I received blister in an envelope. It may therefore be subject to impact deteriorating the lot. I was lucky, she has no problem but others have certainly been less fortunate than me. The minimum would be bubble wrap surrounding it. It's costing him 1 star in my opinion.
