Question about Motorola Mobility RAZR V3
Totally discharging the battery is the way to go. But what you can also do to use your phone in the meantime is this. Plug your charger into the phone withOUT your battery in. It will tell you "Unable to Charge." When it says this, put the battery in. It might tell you "Invalid Battery" a couple more times, but it did eventually say "Charging Battery" for me. After that, simply turn the phone on and it will return to normal. This is when you drain the battery completely. Once I did that, I did not get the invalid battery error again.

My V3 also said Invalid battery to me so I took it out, cleaned all of the contacts and left it for a couple of days.
When I put it back in I then did not turn it on but plugged it in and charged it overnight.
In the morning it had charged and the problem seemed to be sorted. Fine battery wise ever since.
Hope this helps/works for you

Simple solution here...
...totally discharge battery, then remove battery from V3 for about 5 mins, then put back in and recharge for 12-14 hours.
Reason, bat needs recalibration with phone.

I took the battery out, cleaned the terminals with an eraser, then swabbed the terminals with alcohol and left it over night. I put it together and plugged in to recharge but the error keeps coming up "invalid battery."
