Delivered very quickly, even before the maximum date announced (48 h). Very well packed. And perfectly compatible. In terms of autonomy, it is too early to say, this is my 1st use! If it is the same as the original, it is still almost 2 times cheaper. To be continued! Finally, after a year of use, one can say that it is a good replacement battery. But in terms of capacity, it is almost 2 times less than that of the original, despite an announced capacity of 1900 Ah. Finally, for very fair price compared to what you can find also good 2nd battery!
