Absolutely no recommendation to buy vehicles with this type of battery, short battery life and are expensive.

On 07/04/2015 I add: I've turned me over the contact of Stadl Baur homepage to customer service and since I had good luck with a judicious collaborator. She has led the 3 new batteries and I get a new charger. Maybe that went so well because I bought through a dealer from Amazon and I have also sent the invoice where the name Amazon is on it. When I used to be turned me Customer Service Stadl Baur had one myself handled quickly by saying that these batteries have no guarantee and I got no substitute. Perhaps it was also due to the Easter Bunny ???

But I have here rated the product the battery and I can not stand still for good, but I would now adds one star awarded for whatever reason.

When the batteries a note that these are to be removed after use and must be loaded and all I know 4 weeks was also noccmal must be nachgelden etc. This can be in a child's toy monitor bad or think about it at 2 vehicles and 3 batteries. I would buy whole systen micht more, but for something good in a Model-dealers to spend more money for cars with good professional and rechargeable batteries and charger.

Original Review:
I have hunted now 3 of these batteries over the Jordan, that's enough, I do not buy more.
I recommend this system of vehicles not with these batteries.
It's almost unmöglch obtain these batteries alive, much less for a child.
One forgets again to take this battery out of the vehicle and after a few days, has this deep discharge and bye.

Supplement on 30.03.15: The vehicles are cheap and good, the business is the battery, which is like the coffee capsule machines .....

The seller here on Amazon is not exchanged to the battery, should I turn directly to Carrera.
