The Old Ferroresonant MAGNATEK Converters...
These dinosaurs were 30X as common as competitive converters and were a flawed design from the word go... OEM chose the BW Magnatek units because they were the least expensive of the lot. I came a MAG...

I have an 18 year old Magnatek 950 and a 40 amp portable B&D charger. I use the B&D to charge (2) 6v Sam's Club GC batteries quickly then float with the Magnatek for several days. Mine only puts out 13.2 volts once batteries are charged. Is this normal or is the lower voltage due to age? I don't remember if it ever got to 13.8 v when batteries were at 50% SOC.
Normally, low voltage on these means the capacitors on the resonant circuit are getting tired, but for maintenance I would probably leave it be. Note the capacitors are not that easy to find, as they are 660 volt (there is around 50-600 volts on the resonant circuit, so care should be used when servicing).
