Hi,

I'm planning to buy one of these dischargers, but don't really know which one to choose:

ATOMIC AAA Battery Discharger (Ver. II) Price= 20$

1.) Discharge Current:
0.1 - 2.5A (Auto)

2.) No. of Cells:
4 Cells AAA

3.) Auto Cut off Voltage:
0.7 - 0.9V

or this other option:

SKYRC AAA MiMH Battery Discharger Price 30$

•1000mA Current For Fast Discharge.
•Cut Off Voltage =0.9V.
•Aluninum Case For Superior Heat Dissipation .
•Four Independent Discharging Slots.
•LED Indicator For Easy Check Of Discharging Statud.
•Screw Type Battery Terminal Is Comfortable To Fix Battery.

Are they the same, but one in plastic and the other in aluminium?
Is there any difference?
Is one more reliable than another?

Thanks for your help!

I think the most important thing to find out is if the outo cutoff realy works.
Not like my PN that keeps discharging to 0.4V.
I know some people using the atomic one, never heard them complain.
Dont know about the other one.

I used the ATM for a while, havent really had any problems. The other looks more compact, but has a slower discharge rate, so it will take longer to discharge. It will keep the cells cooler, but at 1A, they dont get too hot anyway.
