Only one month of decline for using this battery. So far she has good behavior and attire entirely correct. It is true that the 300 mA / h more capacity compared to the original (1500) are just a little more that can be virtually undetectable. That said, goal achieved because the original cell had trouble holding 1/2 day after 20 months of use. With the new, back up at 1 - 1.5 days depending on use. Now see if these performances held in time. I recommend this product which is 2 times less than a cell of the brand and shipped very quickly in France for Germany for 1 only.
