I'm looking for a charger to replace the Radio Shack one I currently have, which apparently isn't charging my batteries to full capacity, won't take different sizes of batteries simultaneously, and requires them to be inserted in sets instead of being able to charge individually.

This is actually a two-part question - first one is how much would I have to pay for the features I want, second is what features can I get for the price I propose.

Features I want:
smart charger - I can put in a battery and regardless of its charge level or capacity, I can charge it to its full capacity, for example
ability to put in multiple different cells simultaneously - for example 2 850mAh Lenmar AAA's, 4 2300mAh Lenmar AA'ss, 1 1800mAh DynaCharge AA's, 3 2000mAh Panasonic AAA's - at different charge levels - for example one 850mAh AAA is almost fully charged whereas the other won't even light a flashlight, 3 2300mAh's are half charged and the other is almost totally dead, etc.
can accept at LEAST 8 (preferably 10, 12, or even 16) cells simultaneously (AA and AAA size)
would also like to be able to charge C and D (willing to accept it not taking as many cells simultaneously)
an on-demand conditioner - I press a button, and it discharges the batteries until FULLY depleted (<0.001 volts at <0.001 mA) then charges them.
ability to select multiple charge currents (or times or whatever) - so I can do anything from an overnight charge for best performance to a 1 hour or 30 minute (or less) charge for panic mode ("The groom is kissing the bride and all my batteries are dead".)

The proposed price is in the $35 to $50 range.
(I'd be willing to give up a few features, like multiple charge current times (would prefer something between a 1 hour and 4 hour charger), ability to charge C and D, for example)

Among the NiMH AA/AAA chargrers, I suggest these models:

Check out Ansmann8 charger, it's the closest to what you describe. Pictured below is the even bigger "16" model but it is very similar.

I just purchased the AccuManager 20 and have been very happy with it! It doesn't discharge the cells, but claims to use an algorythmic type of charging method to condition cells. I don't have any testing equpiment, but have noticed that it brought some sluggish NiMH back to life for me. It automatically adjusts the voltage based on the capacity and condition of each individual cell, has a 3 year mfgr's warranty and is right around the $50 price range :-)

It's not the fastest charger on the market for AA and AAA cells, but you will probably have to sacrifice speed for the C and D cell charging no matter what.

Thanks for the suggestions.

One feature I forgot to add to the "wanted features" list was a display that shows the charging current and the cell capacity, among other things. I seem to remember seeing a charger that had this while I was looking online a few days ago, but I can't remember which one it was.

The only charger I know of with that type of a display and variable charging currentis the LaCrosse BC-900. Of course, there is some other electronic charging equipment out there with displays, etc, but they aren't 'self-contained' chargers where you just put the cells in and away-you-go (you have to hook up wires and leads, etc.)

yes that's what I was referring to, but I'd like one that could take 8 or 12 cells or more at a time. Would it be cheaper to get 2 or more smaller chargers and use a power strip to plug them into the same outlet, or one big charger?

I think it willjust depend on the priorities of what you're after and what your needs are.

I bought my AlphaPower LaCrosse BC-900 package athttps://www.jsburlys.com/shop/

Though it won't handle the C and D cell batteries, it seems to do everything else you listed. Best of luck and happy charging. Steve
