Cant charge my battery

My 20V battery was stored completely discharged for over 8 months. After all that time I bet the battery was holding no charge whatsoever. When you plug a completely drained battery to a charger the charger will experience a big demand in current and will fault out, flashing red. So we need to put just a little bit of charge in the battery for the charger to start working. What I did is with the battery in charger unplug and plug the charger like 10 times. Every time you plug it in it will send voltage to the battery for a split of a second before the charger fails. Eventually the battery will get enough charge for the charger to start working.

new charger or battery no good.if brand new return.

I had the same issue -- charged it for days and still red light flashing. I was ready to break it open and see if I could replace battery. Then I looked on the opposite end of the charger and seen a little round hole thingy. I put the end of a pen in there and pushed it twice and -- the red light went away . Plugged the charge in and steady red then purple and now blue. Looks like that is a reset ..Try it -- it worked for mine.

The battery is gone for sure... You must get new one... take a look on amazon (my recommendation): Amazon com nailers paslode battery

Try this , it helped me. 1. plugin the charger (or data cable) for about 15 minutes and keep the red light blinking. 2. while the charger (or cable) is hooked to the phone, remove the battery and memory card for 10 to 12 seconds. 3. keep the memory card out and put the battery back in and whalah, it startes up. (really hope this helps)

I had the same problem with flashing red light on my charging dock (within 10 sec after 2nd green light came on). I did fix it. There is a rust brown securing tab that holds the battery in place. Mine must have a broken spring..... So, I put the battery into my camera, pushed securing tab over the battery and then wedged a toothpick tip to keep battery tab in place. Once back on the charger, I had no more flashing red light. The battery is charging correctly. The problem was that the battery was not held down into place correctly. I now just have to unwedge the toothpick tip to remove the battery...but not really an issue at all as I keep the battery in there all the time. Very easy fix!!!
Others suggested to reseat the plastic dock. But mine was secure. Somewhere there is not a good battery connection that is causing the red flashing light. I am thankful to figure it out. Hope this helps you.

Dust getting in the charger is a problem, Try blowing it out with a moisture-free dust remover, found at most any store. Green flashing means improper power, due to dust or power from the outlet, try a differant wall outlet. Red flashing means the charger or battery is to hot and must cool down before it will charge. The charger will not charge a battery if the lights are flashing. Solid Red light means it is charging and solid green light means it is charged. Plug the charger in first before putting the battery on the charger. If the charger has been droped or hit the floor the coil inside could have broke loose and dammaged the charger requiring it to be replaced.

You may want to send an email to [email protected]. In the meantime, try keeping it plugged into the USB port for at least an hour, or perhaps overnight. See if the light stops flashing and stays on. Then try plugging it back into the Wii Fit unit.

My personal suggestion is to return the charger and battery and buy a 15-minute charger and four more NiMH AA batteries than you need for all of your accessories. Not only are AA batteries compatible with all your accessories, but you won't be out a gizmo while it's needing to be charged.

Good luck!

I had this problem a few weeks ago (i.e. flashing red LED). All I did was remove the power plug from the charging unit, turned it around 180 degrees, then plugged it back into the charging unit. Red LED came on steady & the battery (which is the one that came with the camera) recharged as normal.

sounds like a dead battery. Plug the origional charger into it and the front led (below the flash) should flash red. If the red led in the back of the camera flashes or stays lit, then you have the wrong charger plugged in. (the camera won't power up if the back red/green led is on when plugged in)
