So I know it can't be good to short batts. . . Today I was removing fuses to install D3100 #3 when the allen wrench touched a battery hold down post which I didn't even notice (face palm fuck). My question is if it is possible that the lifespan has now been significantly reduced by a brief contact? At least the D3400 and the new D3100 weren't raped but I've got the other two on the charger and the only thing I noticed is that the voltage climbs to like 16v for a couple minutes before coming down to normal charge voltage. The XS manual clearly says to never let it go over 15.5v 5 minutes max or they will gas, could they already be FUBAR? Thanks all
