Every once in a while, I need a 12 v. DC power source to trouble shoot
something. I have been using a battery charger, 12 v. around 6 amp.

Is that okay, or is there a dedicated power source for this purpose?
Maybe one of those power rescue jumper battery pack thinguses? Kinda
spendy, but sure I could score one at a yard sale. How do they last?
Very rechargeable?

Something with variable connectors for the times when you need a clamp, or
just a probe to put the juice at the right place.

Battery chargers are usually charging at about 14 V, iirc. And proly have
considerable ripple.
How bout an ole car/motorcycle battery, kept on a trickle charger when not
using it as a power supply?
