If the battery is indeed appearing as a short circuit then it will probably require a pretty hefty "zap" current to have much affect. I used a power supply that is rated as 15 volts at 10 amps. Lesser current may have done the job. It is not really an exact thing, so you can start with the smallest power supply at your disposal and work up to the largest if the smaller one(s) doesn't do the job. My guess is that a supply of <1 amp will probably not do much good, as the duo is already trying to charge the battery with a current in that range, and it is not have any success. Although, the duo may be giving up (so to speak) prematurely. Perhaps your 1 amp supply connected for a longer period would stir things up enough. It would be useful to have a voltmeter connected while applying power to the battery to see how much the voltage drops. If it drops a lot (several volts) you know that you need more current, or perhaps the same current for a longer time, up to the point of the battery getting warm/hot.
The is of course always a danger present doing something like this. I have never had an explosion or fire, but I often instinctively close my eyes and/or turn my head away whenever doing something that might be explosive. It should be pointed out that I have no dependents. If I had a wife and children to care for I would probably be more careful! Greg > > Thanks.
