Razor v3 wont charge is there anyway to fix the problem

try taking out the sim and blow the stuff out of it. Then put it back together and see what happens

I hooked a 12 volt car battery charger to the battery for about two min. Then I put it in it's own charger,the yellow & green lights came on for about 5 sec. then the red light came on . About 30 min. later the green light came on and the battery is fine.

Your Charger Port On Your Phone May Be Loose or Begining To Have A Break in The Wire, Seek A Phone Technician If You Do Not Have An Advanced Understanding Of Phone Circutry

Hi, I had the same problem with my Old Razor, I bought a new battery and that fixed the problem.
New Batteries for Razors are around £6 - £7 online. google it.

the unit uses power EQUAL to what it is being charged with, when plugged into the USB.
you need to leave it on the DC (cigarette lighter) charger overnight to charge it fully, or use an AC plug for the Motorola Razor (min-USB) to charge it in the house

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.

the steady red light showing when in charger shows that
it is charging. the blinking red light when taken out of
charger or turned on and off means it is not fully charged.
leave it in charger till red light turns green.

reflash the firmware this will correct the charging issues and if that does not fix it then have the mainboard replaced.

plug it into and see if it is connect...if not let me know

You simply need a new battery. Razr batteries are notorious for loosing life and the entire problem is the chargers you are using. You MUST have one with an IC chip that tells it when to stop charging otherwise watch how long you are charging it. Also when you have a new battery let it fully charge and fully die twice before you start normal charging this helps a lot.
