Since the original battery of my Gigaset SL400A service after 4.5 years, bloated that even the cover has been pressed out of the phone, it was high time for a replacement battery. Because this phone only ekes out its existence as a second unit, I wanted to spend no more 25.- EUR for a originalen- battery. So I ordered this battery here because it is cheap and 250mAh has more to offer. The battery was recognized without problems and semi-loaded on the phone. The battery makes his service so far as good and long as the Compatible- battery. Qualitatively there's nothing to complain about and fits perfectly into the phone. With 250mAh more effort should be directed to keep an extra day I put the charger always off when the battery is fully charged. Eco and Eco + are activated and the display outside the charging cradle always enabled.
I will report from time to time, when I have the battery two or three times a full charge and discharge cycles.
Addendum:
15/02/2015 With the settings set with me, the battery lasts nearly 5 days with the unabridged original battery it were at the same settings 4 days ...
