Is flooded equalization charge always timed?
I have (2) of the 6v interstate costco batteries. Would like to do an equalization charge on them. Using the Trojan users guide for directions. Trojan is saying to equalize for 2-4 hours. But it a...

I eq'd some 3 yr old costco interstate gc2s today. Not sure when they were last charged.
Put my meanwell set to 14.8v on them. 32 initial surge amps tapered to 1.1 amps in about 45 minutes
Electrolyte level in cells midway.
All cells 1.260 +/- 0.003.
Crank up meanwell to about 11 amps. This is 15.64v.
12 minutes later specific gravity has not budged. Amps tapered to 7.65. Crank it back up 11 amps. This is now 15.92v
10 minutes later amps holding at 11. Specific gravity jumped to 1.270
10 minutes laterthey are accepting 9.92 amps@15.92v sg 1.275.
Crank it back upto 11 amps and now 16.11v
8 minutes later 1.280 same amperage and voltage.
10 minutes later 1.283 same voltage but amps rose to 12.67.
Terminate eq charge.
Topped up cells with distilled water. Set it to 15.5v. 6 amps.
15 minutes later 15.5v ampsrose to 6.97 did not bother checking SG.
Remove meanwell, clean off whitefuzz from hold down hardware,and go home.terminals still coated in red wheel bearing greaseiput there last year,
and corrosion free
Top up screw31 in workshop with remaining distilled. 2 cells plates were exposed.
Relatively slow Charge still in progress, but it was accepting 40 amps briefly at 14.7v before i cranked the dial way down to low mid 13s and sub 11 amps. But some of that was powering leds and fans.
Got to go raise voltage now in a few stages. Perhaps dip the hyddrometer.perhaps just watch the ammeter and terminate when amps stop tapering and begin rising.
If the screwy31s performance was judged solely by the ability to power 12 to 30ah each night.
Then i could say it still going strong!!!!
But the fact that 100 watts of dedicated solarpanel can no longer get the battery above 14.2v,even when not discharged the night before, In strong sun all day.....speaks otherwise.
