OK, so I missed that. Here's one that does address the dead battery you would be connecting the vehicle to. My apologies for missing the dead one that is not charged. Link is below: https://blog.napacanada.com/en/how-to-safely-and-quickly-recharge-a-dead-car-battery/ There are similar articles to connecting batteries to capacitors (which is basically what a battery essentially is), although we're dealing with DC circuits. Good Luck. Charles Lucas |

Driving around can't revive a battery below 12 volts, and attempting to do so might damage the alternator." If that is true, what has worked for practically everyone that has ever jumped a significantly discharged battery has risked damaging the alternator of the car used to jump it. Ever hear of that happening without reversing the cables? And driving around has worked fine for millions of people with battery drained before jumping after they left the lights on. Parts dealers web pages are highly "sales biased", like the one I saw that claimed that wiper blades should be replaced every 6 months. |
| "Peter W." <peterwieck33@gmail.com>: Jan 30 11:41AM -0800 This is the 94th post on the basics of separating fly-shit from pepper - oops, how to jump-start a vehicle. What we have learned: a) this venue is proof-positive that common sense is rarer than an ethical politician or a moral evangelical preacher. b) that this venue exists to give the most impractical, obscure, possibly dangerous advice to the mostly lazy, ignorant or otherwise challenged individuals who appear to look for and cherish such device rather than seeking it for themselves, or reaching out to organizations that actually might know. c) that if there is an opinion - fact-based or not - there will be an equal-and-opposite opinion - fact-based or not. d) that the posters in this venue as exemplified by the above should not be exposed to anything sharper than a rubber spoon, more powerful than a D-size battery (large enough to make swallowing it difficult), or requiring reading or understanding directions, written or otherwise. https://magazine.northeast.aaa.com/daily/life/cars-trucks/jumping-a-car-battery/ Now, how hard was that?

The "bad" battery will start charging when connected, and there will be no current limiting. -- Cheers, Carlos. |
