29, 30, and 31, are acid starved specials, just like 65's and 34's.
They scrape by in engine starting duty but fall flat on their face if cycled. A real hoot was Delco's calcium/calcium sealed RV battery. Known as the single cycle special. After 1 discharge the "eye" stayed red until shortly after when the battery played possum.
The mark of a crappy quality battery is flaky hydrometer readings. They reflect poor capacity, horrible charge efficiency factorials and early death. The battery regresses to its evil habits very soon after a lengthy equalization. I have had scumbag brand golf car batteries revert to .03 differential 5 cycles after equalization. Six months old. The owner of the Screwy Battery described a charge regimen of jamming 200+% electricity back into the battery. Pretty much a disaster as far as Charge Efficiency Factor is concerned. Using CEF to determine health of a battery is a good way to stay out of the swamp. This is true for any rechargeable battery including lithium with all of the variants. If a battery advertises CEF of 1.15 and you find yourself at 1.26 Houston, you have a problem.
