Ultra 8 Cell Rapid AA/AAA charger

I found a charger on Tigerdirect and I want to know if it will be any good. I currently have a timer based charger so any smart charger would be an improvement. I just want to keep cells charged for my Mini-Mag and my camera (if necessary).

Personally, I'd look at the MH-C800S or the MH-C801D if you're looking for a good 8-Cell charger. I own the C800S and have been very happy with it.

I've not had any experience with that charger, but I'd want to know more specs, such as the charge/discharge rates along with any built-in safety features.

Hello Jrmcferren,

That unit looks similar to the one that Amondotech is offering. I have no experience with the Tigerdirect unit, so can not comment on it.

The 8 cell Amondotech charger is made from two of the TG2800 chargers. The TG2800 is a very decent charger.

If you get the one from Tigerdirect, let us know how you like it and how well it works.

I'm getting this so I don't have to discharge my cells all the way to prevent an overcharge, like with my current timer charger.

Ok, I got this charger on Wednesday.
The charge time table and the specs do not seem to agree on the charge current. I had to do a few manual terminations (reset the charger -dV not detected), -dV not detected terminated due to how hot the cell gets, and so on.

When I try to do NiCd I will have a fan over the cells and will monitor for abnomalities. I don't know if this charger will adjust charge current automatically per chemistry or not.

Hello Jrmcferren,

Interesting...

If the -dv is set to a higher level, it may account for the higher NiMh cell temperatures. Perhaps it was originally set up for NiCd cells...

NiCd cells usually don't heat up until the end of the charge, whereas NiMh cells heat up throughout the charge.

What are you getting for charge times?

I'm not timing them, I'm just topping cells off anymore now. The instructions say 2.5 hours for 1 or 2 2500 mAh AA cells.
