How to Jump Start an Aibo ERS-210 Battery

WARNING: Try this at your own risk. With ERS-2X0 batteries there is a risk of frying the PCB through this method and making the battery non-repackable. I have never encountered this issue myself, but it is a legitimate concern. There is a difference between a dead battery and a battery that has dropped below the voltage that the charger recognizes. This method will not work on a battery with dead cells and could be dangerous. A lot of people don't seem to know this trick and I didn't learn about it until late last year, so I wanted to share it with everyone so no one has to pay for a repack on a working battery! You can skip the middle five minutes or so of me actually jumping the battery because it is not very interesting, but I wanted to show the whole process so people know not to give up if it doesn't work at first. Also, ALWAYS be very careful when handling Li-Ion batteries. These can be major fire hazards and when a battery fails to charge, it's because the charger has detected a problem and will not supply energy to the battery as a safety feature. In many cases, the battery has just been run down too far, but some batteries may have more serious issues that could pose a risk if energy were delivered to them. Do not try this for over 100 repetitions or if your battery has any strange lines or dark spots on it and stop immediately if the battery begins to heat up. Do not leave Li-Ion batteries on the charger unattended and never take apart an Aibo battery for any reason.
