- Never ever try this suggestion, as a car battery (especially a healthy one)
- is capable of delivering 70-80 Amps through the NiCad, which might cause
- the NiCad to explode. Always use a device with controlled current. If you
- can't revive the NiCad with about 10 Amps, throw it away, it's really dead.

- I reply:
- The only reason I mentioned using a car battery is that I've seen that
- suggestion made in this newsgroup before. The poster of that suggestion also
- said things like [paraphrasing] "if the cable welds itself to the battery
- pack terminal and you can't pull it off, RUN", and "this is very dangerous."
- I agree. I recommend NOT using a car battery, for all the reasons mentioned
- and others not yet mentioned. However, in theory, if you tried it and lucked
- out and nothing bad happened, it would work, and perhaps knowing that will
- help someone imagine other, safer, equally effective solutions.
