I have 1700 and 2000 nicds from 6 years ago when i raced i slow charged them and drained them down using the 10 bulb with deans discharge unit and recharged them with my Astro #110 D at 4.5 amps the readings i got on the 1700's 1795ma at 16.5volts . What are the chances these battery's may still be used for sport running ? I realize to compete 3300 mah nimh cells are used, any info would be good.
