need voltage of fully charged high capacity battery

[daseth007]

I have adapted a nokia 6100 1300mAh battery to work with my siemens sl45 sw56. But i have the feeling the battery isn't fully charging. When fully charged(12h of charging) i read the voltage with an external multimeter and it shows 4,13-4,14 Volts.
What i want to know is what is the voltage a battery this size(1300mAh) should be charged at without any problems(killing the battery or shortening its life). I want to know this value because i vant to increase the charging voltage using SST but i don't want to kill my battery.
help from people with high capacity batteries(over 900 mAh)is wellcomed.
if anyone has gone through the trouble of measuring their battery voltage after fully charghing and fully discharging their accu please write values here. it would be very helpfull.

I'm not sure but, know that it's 4180 mV when bat is fully charged.

i've tweaked my phone with SST 1.3 and now my battery is 4.20 V fully charged and 3.45V-3.50V completly discharged. I belive it is ok this way.
Does anyone know if the LiIo batteries have shorter live if they get extra discharged. And what is considered extra discharged?
