Both batteries charged but nothing there on my bosch drills
You did not say what kind of battery they are. Most lithium batteries will die if they go lower than a certain voltage. Going to zero volts will do that. That can happen when you leave the drill in the garage, where its not only hot which is not good, but not using the battery for long times it will drop in voltage until it stops working altogether. There are ways to try and repair the batteries but it is a dangerous thing to do if you do not understand. I can't share that with you because it can be dangerous. You may need to search Ebay for a new battery, and be sure to keep it charged and out of the heat of a garage. The battery charger should not indicate that the batteries charged, it should indicate and error. So your question did not give enough details for me to give you anymore information.

Has anyone else had problems with the BOSCH "BC004" Battery Charger???
The problem is resistor R3 on the circuit board.
Since there is 310 Volts (!) across this resistor, I would highly recommend taking it to a TV repair shop for repair unless you know exactly what you are doing and have the skills for repairing a PC board. Take this email with you when you go there.
Be sure !!! to discharge the two large capacitors with a 10K resistor before attempting this repair - for days they will retain 165 Volts each across them after the power plug is pulled.
The repair is easy - simply replace the resistor R3 with two 130K metal film 1/2Watt resistors in series. The existing resistor is marginally power rated and there is too much potential difference across it for safety. Make sure the two replacement resistors are enclosed in a heat-shrink tube before soldering onto the board.
