Just a note on battery chargers for electrolysis. If you have a newer, electronically controlled charger it may not work. Something in the circuitry will turn the charger off when you connect the leads to the bath. Instead, try one of the many old wall warts most of us have. Just make sure they are a DC charger and not an AC. I use one from an old laptop power supply and it does a good job at about 3.5 amps. Many wall warts are much lower amps than that, but they will do the job, just take much longer.
