Trickle Charging LSD Cells

Common knowledge says trickle charging is bad for low self discharge NiMH cells. But how bad? Should one care? This test is to give us some answers.

Test Method

Test performed on SkyRC MC3000 for its accuracy and ability to terminate on 0dV and Fujitsu White cells for their consistency. The test consists of these steps

  1. discharge the cells at 1.0 Amp (about 2 hours)
  2. charge the cells at 1.0 Amp, terminate at 0dV (another 2 hours)
  3. trickle charge the cells for the remaining 2 days (44 hours) with 0mA, 20mA, 50mA, and 100mA respectively
  4. repeat steps 1-3 until feasable

This test is going to take months to finish…
