1. clean, adjust H2O as necessary.
2. Preliminary charge - watch for shorts and other anomalies.
3. Bulk charge. - Usually to around betwen 14.5- 15.5V.
4. Bulk charge manually switched to lower current to remain around 14.5 - 14.9V
5. Eq charge at low current for a day or more if the SG indicates further progress is likely.
6. Long float charge. Again, if the SG has shown signs of improving then continue until improvement has practically stopped.
7. Rest. - after rested, test SG & Voltage and check for shorted/shorting cell.
* This may be the end of the charging regime for a lucky few.
8. Load test (in multiples of 65 Watt h/lamps at the moment). Discharge batt to between 10.5 & 11 Volts, Add EDTA, Pulse-charge slowly up to (usually) 14 -14.2 Volts. - This can take a day or much longer.
9. Adjust electrolyte, load test again.
10. Final (hopefully) charge.
This is essentially what I am doing.
* I have noticed little difference between pulse-charging using my 1 - 3 ppsec setup and a carefully monitored & lengthy manual charge. Perhaps others have more obvious success with pulse-charging over other methods than I have?
* I have two surviving pulse-chargers at the moment. One charges a 30,000 mfd cap at about 28V and discharges this into a batt at a rate of 1pps. I can select the pulse duration between 0.5 secs on - 1 sec off, and 1 sec on - 0.5 sec on.
The other is similar, but the caps total about 16,000 mfd, and the Voltage is in the region of 60 - 80 V. (This blew the MOSFETS in short order). It is now effectively attenuated via a sturdy rheostat and other resistance elements as necessary.
* I have noticed more success with the little pulse-charger over an extended time than I have noticed from using the larger one. But it is not so clear at the moment.
