Step-by-step instructions:

Items required:
Multimeter, 20 V DC
Thermocouple thermometer
Variable power supply with adjustible voltage and current limits of 10-20 V and 3-5 A
3-10 A dummy load (24 V halogen bulbs, or 2 car headlamps in series will work if you don't have a proper constant current load at your disposal)
Stopwatch

1: Check cell voltages, confirm that there's no dead cells, all stick pairs should be over 14,3 V
2: Set lab power supply to 18 V, 3-5 A current limit and charge each stick pair until temp reaches 40 C
3: Discharge at 3-10 A until voltage is 10,8 V, and use stopwatch to note the time. DO NOT DISCHARGE UNDER 10,8 V!
4: Allow to cool to 30 C or lower
5: Recharge with the lab power supply at the same settings as before, until temp reaches 40 C, then terminate charge
6: Repeat steps 2-5 one to four times, until capacity stops increasing

Good luck!
