It took a while for someone to come up with the reason for the reason for the old "you must disconnect the
battery before recharging it." Must be less of us old buggers on the net these days (are many of our generation dying off?)
I disagree with this being a myth. If you still have one of those old chargers around and you wish to use it then disconnect the
battery first. Some of those old carbon pile and Tungar tube rectifiers could put out some pretty ropey outputs. A lot of those chargers would put out some furious outputs for fast charging applications (charge your
battery in 20 minutes.) It was better to disconnect the
battery than.
It's a case of knowing what you are doing. The modern 12 V chargers are
well behaved, nol need to disconnect. If you do hapen to have one of the older style chargers then disconnect.
