Unfortunately, just at the beginning hui ...

After I had the battery about 3/4 a year in use, it is necessary to clearly advise against this replica.
Initially equipped with a running time of just 2 hours, this fell to less than 1 hour.
Particularly annoying is the totally inadequate indication of maturity.
If one looks to the start of work on the term and is in good spirits, to end this well, are at 5 minutes in the office only 45 minutes available.
This means that the capacity does not continuously after but extremely erratic. So after 30min again an external power source must be driven.

Of course, these experiences were always carried out with the exact same settings on the computer. The battery was when he was charged, disconnected from the mains and then discharged to 10%.

In my view, never provide these quality replicas of an original battery, which admittedly has also twice the price.
