More power than the original LG

I have looked after one year, two batteries ordered because I am much on the train on the way and the battery is thus sucked literally. The original battery in my LG-P990 keeps doing no sixth-hour ride through the tunnel and because of the bad power through the overhead lines. The Polar Cell holds since almost nine hours. Home creates even two days without recharging, where the original after only 20 hours, the hooves tearing up.
From the other reviews I conclude that the importer under the same label several manufacturers offering with different quality. I am fully satisfied with my two batteries and can recommend it only. My first Polar Cell battery has thrown after one year an acquaintance in the trash because he thought it would be a match for any packet-Hotel. Even after one year no fatigue was evident. Now I'll see what the two new batteries are good.
Tip: To remove the battery easily from the phone, I have a small strip of adhesive tape adhered to the lower edge as a tab to single out the battery.
