Deep Discharging NiMH LSD Cells

Does deep discharging harm NiMH cells? To find out I ran a test.

I took two Panasonic eneloop AAA cells, labeled one Test and the other Control.

I kept charging both on OPUS BT-C700 at 700 mA and

Every 5 cycles I measured the capacity (TEST function) and internal resistance (QUICK TEST function) of both cells on OPUS BT-C700.

Here is how the cells performed.

Conclusion: Deep discharging Panasonic eneloop AAA cells causes their internal resistance rise 2 times quicker.
