The battery fit a little tight in the SK17, the advantage it does not dissolve easily and fall out. Can not fault on the part. My phone is working normally again. The original battery had passed away and died with a hard-to-follow error image. When logging into the network, the SK17 crashed. In flight mode, it still held by, seemingly no longer brought the "old" the necessary power under load. That's over now. The spare battery in, reasonably fully charged and all was well again. Its price is worth it. No negative points on my part.
By the way I have in the context nor the useful app "Battery Doctor" discovered. The now cares drum that I no longer so much torment and discharge the battery to get no.
Résumé: Who the EP500 Sony had in his unit, associated with this replacement battery is a viable alternative that probably has slightly more capacity possible (in any case not less;)). Anyway, in my opinion fit your price and product quality together.
