A colleague has a very flash Corvette which is very seldom driven. To counter the constant drain he maintained with some expensive modern smart charger. When he went to start the car the $350 (L170) battery exploded , the whole end blew out and acid everywhere but fortunately largely contained by the battery housing. I cannot recall the figure but i was surprised at the voltage it maintained. now runs through a timer.
A charger I use on the very rarely used inherited "modern"' Jazz pulses at 13.2 volts and settles to 13.1, lower than its claimed 13.7 performance. Other makes claim to float at 13.6 but all are primarily for Ca batteries.
The advent of Ca batteries, now often not distinguished, has complicated everything and rendered much older advice practices and voltages obsolete.
i dunno what present 6v are, but Ca batteries with their 14.6/7.3 or so limit seem unsuited to original Sevens reliant on in car charging.
In the days of the cap type battery connectors I have had mysterious effects due intermiitent connection on 1960s car. Did in two bulbs on a tour but did not twig. Only months later did it suddenly fail to crank
