No, not really. If the battery is trickle-charged back to full strength, it may go on with no further problem for a long time. But every time a battery gets dead enough to need charging, it "takes a little something" from the battery, and ultimately, it has a shorter life than it might have had, if it has had to be recharged repeatedly.

Have a 480v industrial battery charger that still arcs when plugging it in after changing the 3 phase male cord cap the 20a outlet and pulled new wire?

Shut the charger off when you plug the charger into the battery. The low charge on the battery will cause arcing when brought into contact with the charger. If the arcing continues with the charger shut off check the diode bridge in the charger, there may be a blown diode gone to ground. Make sure that the output of the charger is smooth DC at the proper voltage output. If there is a problem with the battery, the over load protection on the charger will trip due to excessive current draw by a faulty battery.
