Another point in their favor is that it seems 6 V batteries are able to recover better after being discharged for a long time. The 51 2-door hardtop I'm tinkering with had not been driven since 1981. I figured the battery would be sulfated beyond help from sitting so long, but after a few charge/discharge cycles, it can crank up a 216 I've got on a run stand in the school shop! Not bad for a battery that sat unused for almost 30 years!
