Huh? The wire length limits the charge current? I may be dense but you
are going to have to explain this to me a bit more.

How else would you control current other than with an appropriate
length/size of wire? You can if you wish coil it and package it and call it
a resistor.

Perhaps he is able and willing to stand by the battery and monitor the
process, but I'd rather buy a charger: it could regulate the current,
measure the amp hours delivered, and shut down automatically when the
battery is fully charged or the time has run out.
