If your battery is totally flat some chargers see this as connecting to a short and will not charge. If the battery has a charge run it down some, my batteries often don't take much of a charge if any. Does the charger light up.Does the charger have any fuses on its out put wiring. Open the charger up, do you see fuses. When the charger is on do you see any blinking lights. If you get a blinking yellow light when hooked to a battery there is something wrong with the battery. Hope this helps
Batteries don't always look degraded but if they've been in use for a while or have a bad cell, they will show up bad on the charger and it won't charge them. The only way to test the batteries is to try to charge them on another charger. If the batteries show defective on another charger, they are bad and you'll have to replace them. Also try to charge some batteries you know to be good on your charger to see if it's the problem. If your batteries charge on another charger, your current charger is bad and they don't have any replaceable parts in them so you'd be looking at replacing it.
Red light indicates that the battery is charging. The light will goes off to inform you the charging is complete. Possible that the battery was alreay damaged since you left it charging overnight. Charging time is approximately 5 hours only.
I suggest that you have to replace your battery with a new one.

I had the same problem and found a solution on another forum...
Plug the battery into the charger. The yellow and green lights come on. Leave the battery plugged into the charger. Plug and unplug the charger power cord from it's power source a few times until the the red charger light comes on..... problem solved!
I think the "smart" circuit in the charger that is supposed to trickle charge before the regular charge cycle needs at least some battery power to test and start the cycle. If the battery is totally discharged, the test can't deternine the battery status and will not charge.... Plugging and unplugging the charger seems to bypass this teat and charge the battery normally. The charging process should work normally after this method.
all chargers show a light of some colour when charging , green or red , depending on make of charger , when the battery is fully charged the unit monitor this and automatically switch of to stop from over charging , a safety feature that has to built in for safety reasons ,
It is supposed to stay on. If it is blinking then your battery has gone completely dead. You can force the charger to charge the battery by applying a voltage (AA battery w/ wires worked for me) across the charging terminals while inserting the battery. You'll have to take the charger apart for this.
The Sidekick 3 is notorious for having the charging port go bad. New battery or charger doesn't help when this is the issue.
YOu can get it fixed for around 100 dollars or ou can get a charging cradle that has a spare battery charger. Since you have an extra battery it will work well for you. They are about 30 dollars from ebay.
If you use
a car charger, use a wall plug instead and replace the battery;
because a lot
of car chargers can harm battery life…especially if that is all you’ve
Also check the settings on the phone, if you have disabled power saving
features that dim the screen after so many seconds then the back light
drain the battery very quickly. Use name brand batteries and not the
come with the phone, Sometimes the ones
that come with the phone can ****. Finally, make sure that you do
have a short in your wall charger and that the first time you use a new
you charge it fully to begin with and don’t charge it again until it is
completely depleted. Supposedly newer batteries do not have to be
primed, but I
find it is a good practice anyway. Use the charger that came with your
phone, the voltage/amps are not always just right if using a radio
