There may be a short in the motor or wiring, or the gearbox is broken or otherwise seized up. Dewalt provides replacements for most parts at reasonable prices, so it's worth taking the drill apart to find out what is going on. I suspect you will find damaged wiring inside due to overheating; you may be able to identify the problem by seeing where the wire insulation is charred or melted. Unless you have a good drill of the same model so you can compare electrical resistance, it's a bit hard to ID a bad motor with an ohmmeter. However, you can try visual and olfactory inspection - if it looks and smells burned, it probably is. You still should check the transmission to make sure it isn't the source of the problem.

You may have a failing capacitor on the secondary side of charger power supply circuitry. The output voltage will be low or have a lot of ripple; this would cause the error detected. Pictured below is a bad electrolytic capacitor next to several good ones (this is not from a battery charger). Notice how the top is bulged upward instead of being flat - it indicates pressure caused by the capacitor burning out.

There are other failures that could cause this error code, but this one is highly probable.

Yes, when a battery is being used for a long time, you need to let it cool down and take it to charged. Although there is many fast charger now, but in order to protect the battery, I recommend you to buy a second battery for replace.

And, if you do not know where to find the right one? Here is some suggestion for your Dewalt DC920KA Battery

When a Dewalt charger is showing a fast blinking red light it means the battery is no longer chargeable. It may be because of a bad cell or short inside the battery. Whatever the reason the charger will not charge the battery and it needs to be replaced.

Rechargeable batteries do have a lifespan, they won't recharge forever. If you have fully discharged the batteries then fully recharged them and they still don't have full power or they only last a couple minutes then they are done. If they won't charge or the charger shows them as defective, the only fix is to replace them.

it sounds like you have a problem with the switch or battery. Try cleaning the battery contacts first and then remove the battery and look into the tool and see if the switch contacts are bent not allowing battery to seat firmly. If that is OK then I would think that you need a new switch. MAKE note of how you remove it because it is polarity sensitive. Let me know if you need more assistance.

I am thinking the switch or motor is bad, check the switch first. you can locate parts at dewaltservicenet.com. Make a wiring diagram before removing anything, these parts are polarity sensitive.

Depending on how old or more to the point how many times you have already charged the battery, it may be worn out. All rechargeable batteries do reach a point where they won't charge up anymore. If you have fully discharged the battery and tried to fully charge it up again and it won't take a charge or only lasts a few minutes on a charge it may be time to recycle it and buy a new one.

Go to http://servicenet.dewalt.com/, put your model number in the "find parts" search box. A couple models of the DC825 come up, select yours and on the right side of the product page you can download the parts breakdown and manual.
