Sirs,
I am on an "old man" streak Emoji. Turns out I installed one of the batteries (lead acid) backwards and charged the pack for about 6 hours and of course had no real power. Studied the installation and found the problem (me)! I disconnected it but now I am uncertain of my next step. With red tester lead on + post and black on - post shows "6.2v", reversing the leads shows "-6.2v" so I'm thinking the polarity did not reverse.  Should I charge it separately for awhile or just reinstall it among the pack and start charging (and thank my lucky stars)?

Again, thanks for your collective expertise.
Mike

A few of the old-timers on the EV Discussion List used to recast battery
terminals in their own garages.  They wrote about it and here's an edited
version of the thread.  Not to be a downer, but sorry to say 2 of the 3
writers, Bob Rice and Roland Wiench, are no longer with us.

Note that I don't really recommend trying this yourself. The writeup is
mainly intended for information and entertainment.  To find an expert in
the recasting and/or repair process, try industrial battery suppliers.
