I want to build a 12volt emergency lighting system for my house with some old car batteries that I have. I'd like it to be when main power supply fails, it switches to emergency lighting of the batteries. I will be building a grid throughout my house to do this...it's going to be a lot of work since I will be placing lights pretty much everywhere, even on the staircase, on every step..... Any tips and/or suggestions?
Also, my cell phone (nokia 6230) is having problems in charging the battery.....it charges it up and depletes it in around 17 hours... I know it's not the battery because I have bought 2 brand new ones and the same problem.... When I checked the voltage being supplied to my battery from the cell phone when charging, I got 2.8 volts. My battery says 3.6v 850mAh. A friend I have told me that its probably the power regulator in the phone...is this easy to fix?? Thanks a whole bunch!!
