A/C output from battery charger

Posted by William A. Cormack (wacormack@…>)

In the past year or so someone posted information about battery damage from A/C current leaking into the output of a battery charger and, therefore, into the battery and damaging it. It seemed to me that they said anything more than a very small voltage shown on an A/C voltmeter across the battery terminals was detrimental. I’ve searched both the current and old archives for this but can’
t come up with it. Can someone re-post or otherwise let me know what a/c current is acceptable, if any, please?
