After the original battery is quite expensive, I decided for this product. I have never regretted the investment: compared to the original battery, I could notice a difference either when charging and in use - the battery is reliable and allows to manage a longer time without recharging. In this respect, this battery offers a second battery. I use it for the past several months, even a Kapizitätsreduktion I could not find andCountry.
I would buy it at this point at any time, as a summary assessment is only a 5/5.
