The charger is doing what it is and for my battery does that.
Whether the service life also hinhaut reasonably, I now can not judge. Do I hope not;)
IMPORTANT: This article image suggests that you get a charger with a plug including cable..
But that's not right, because the charger is designed so that you always get sent with only the respective adapter plug for each outlet in the country.
Because you can then either to the two poles of Stadtion it stuck or arrange, if you eg only loads in the car. Overall a rather unsatisfactory solution.
Therefore, a total of 3 star - average.
