difference between MH-C800S and MH-C801D

The main difference between the MH-C800S and MH-C801D is the charge rate. The 801D charges at 2000mA, so 2700mAh AA rechargeable batteries take 1.35 hours to charge if completely flat, and 2100mAh low discharge AA rechargeable batteries take just over 1 hour. The 800S charges at 1000mA, so the 2700mAh batteries take 2.7 hours to charge if completely empty.

Both battery chargers have a “soft charge” function which will charge at half the normal rate.

The other difference is that the 801D has a commercial grade power supply with a DIN connector, whereas the 800S has a smaller wall-wart style power supply.
