After 3 years, a new battery was due. I had already 1 year ago replaced times, supposedly there was an original but there was evidence that the not so was and after 6 months he was also broken. My original has been doing for 3 years, but is now out quickly. So now I have this bought here and am surprised he is doing what he should, and he has a subjective longer performance than my old to its modern era. I travel a lot on the internet and now I'm most of the day from it. Now he has to prove itself and show that he still does well in 1-2 years. So far he gets from me a praise and a clear recommendation.
