Attention! Battery is not fully charged in the separate battery compartment!

In a separate battery compartment is the battery unfortunately only up to max. 75-80% charged (with decreasing tendency, because it was getting worse).
I did it with three different batteries tries (1x original Samsung, 1x Avanto battery, 1x Polar Cell Battery) and had even a trial basis over 24 hours in the charging cradle - but unfortunately always the same, weak result.
While the customer service of Avanto asserts that this error does not occur at their charging stations, but it is my opinion to exactly the same product as here ->; qid = 1348035567 & sr = 8-3 with its Avanto lettering!
And there the same problem is detailed in the reviews!
When I did Avanto reminded me a credit was offered instead of a repair or replacement. So you must be aware of the problem and it is not probably an isolated incident ...
Item returned anyway and is not recommended!
