Question 1

NewEgg says in description that it's NiMH/NiCD.. but when looking at the picture of the box it only says it will charge NiMH. Which is it???

Accepted Answer

Dear Nicolas P,

Both.

Go to the Maha/Powerex MH-6000 site.  Look at "Description".

I've sent a request to "the manufacturer" for the instructions download site.

I'll attempt to reply again after Monday, March 16, if I receive an answer.

Note:  I've used this charger on NiCad (NiCD) cells and NiMH cells for my amateur radio hand held transceivers for several year in different countries (100-240 VAC) and from various 12 VDC sources.  It's still working well.  Best and most versatile AA cell charger, etc., I've had so far.

Sincerely,

Robert M

Question 2

At what rate of charging is right for the POWEREX MH-8AAI-BH 2400mAh?  I don't want it too fast and too slow of charging that may damage the batteries.  Thanks

Accepted Answer

The best charge rate is about 33% to 40% of battery capacity. So a battery that is rated at 2000 mah is best charged at 700 to 800 mah. You can charge at a higher rate if you're in a hurry but it will diminish the life of the battery. Never charge below .3C or above 1C (C=battery capacity) If you charge below .3C, the automatic shutoff may not shut off. Above 1C may fry the battery or even cause it to explode. DO NOT TRY TO CHARGE ALKALINE BATTERIES IN THIS CHARGER! It's a good way to ruin this charger. Alkaline batteries are a higher voltage and aren't meant to be recharged.

Question 3

Where is this device manufactured?

Accepted Answer

The units are manufactured in Taiwan.  Having purchased two of them back in 2013, they seem to be well engineered and well made.  I am especially impressed with their measuring accuracy.  If you get one, be sure to read the documentation start to finish before use.  That is important for proper setup of various charging and/or analyzing situations.  These units are designed for use by electronic technicians and engineers who can understand their use, NOT consumers.
