Question about Vtech i5808 Cordless Expansion Handset
I've been having problems with short battery life on my Vtech
5.8 Ghz model CS5121-2. Tried "zapping" the 3.3 volt batteries, which helps for a while.
Determined (via DMM) that the base unit battery charger reads
10.45 volts DC no load - while the remote charger reads 12.5 volts DC no load. Xfrmr output is supposed to be 7.5 volts according to info molded into the unit. Might be the problem!!!

This model of phone have serious problem regarding the battery. This phone use a lot of juice out of the battery. I'm pretty sure that when your battery is foul charge it doesn't do it. So the problem is in the handset. When your battery starting to get to low you loose your connection. Why?...Because the detection to LOW_BATT in your handset is not calibrate adequately. So it thinks that the batt is weak, to weak to make a conversation.
The other problem could be that your handset doesn't really foul charge your battery. So when you are to far from the base or talking for to long . There's not enough power in the battery to raise the output signal level(db) to your base.
