[RE-wrenches] Battery polarity check

[Mark Dickson]

Happened to us once too with a Surette S-530.  Now that "free" battery sits
in my home's bank with some sharpie + and - symbols on it.  Easy to see how
the symmetrical cap could be placed on backwards.  Seems a keyed notch on
the cap would prevent that. . .

 

Best regards,

Wow. I always check my batteries for voltage when they arrive before
installation. I never thought to check the polarity. I'll look for that
negative symbol on my meter from now on!

Hey All......just wanted to send out a reminder to not take the markings on
the terminals of batteries for granted.....we were installing a brand new
bank of 2V 2400Ah batteries today and had one battery mis labeled direct
from the manufacturer......had the potential to be catastrophic, just so
happened that luck was on our side.......I will not be relying on the
manufacturer's polarity markings any more.......
