In the old days they did it all the time, course you had to have a

If you have 2 half dead batteries it is possible to use them to juice up
one
battery completely and leave the other dead.

I dont' even see how you could do that. with jumper cables? no.

with a power inverter and battery charger? no, (not really)

your "half dead" battery won't produce enough power to keep the
inverter AND battery charger up (ona 12v. system) 14v DC [+/-], at
least for any real length of time to charge the other "half dead"
battery. especially fully charged.


Tim:

I can do it with two capacitors and a set of jumper cables. It is called a
"charge pump" which is a common type of electronic circuit for
transferring charge from a low potential to a high potential. The
circuitry is explained he

http://en.wikipedia.org/wiki/Charge_pump

The power inverter and charger will also work just fine. From this link:

http://www.batterystuff.com/tutorial_battery.html

You can see a discharged battery produces nearly 12 volts (says so in the
above link). The discharged battery just can supply high current at 12
volts, which is fine you just have to set the charger at trickle charge.

An inverter can operate on DC voltage inputs of of 10-15 as seen he

So it will definitely work with a fully discharged 12v lead acid battery.

Heh.

it will discharge faster than it is charging

Now there's an honest answer!

It recharges the batteries much faster than the inverter uses the power up.
If you leave it running, you can even run an electric trolling motor from
the surplus power and eliminate the diesel or gas engine that gives so much
trouble.

This works even better if you have a small thermonuclear charger like:

Pay no attention to what it says about radiation. Russians have been
running their navaids off them for years!
