It should also have a discharge mode and ability to evaluate life/capacity.

I'd like it to be a "table top" model, rather than those big chunky plug-in/wall-wart types.

I have a now discontinued MH-C9000 which works well enough but after a couple years of light use, the aluminum electrolytic capacitors needed to be replaced.  This is not the first time I have had to do this and I suspect this is a common problem on all similar chargers.

It has a poorly designed user interface which apparently the MH-C9000PRO which replaced it has fixed.

Really, how did you figure out the caps are bad? Did it show some signs or you just opened it? Mine still works well for many years but now you made me worry.
The user interface looks identical to me on the pro.

I have a LaCrosse BC-900 charger that I've been pretty happy with. A major downside is it only handles AA and AAA cells although I've used clip leads and magnets to connect it to larger cells.

I have this model as well but I can’t recommend it. It cooked my batteries. Maha never does it.

beanflying:
Not a fully recommended product as I have only used it 5 or 6 times and it lives in the truck for on the road use eBay auction: #154503330184 but fairly well put together for the price point and independent charging of each cell. Cells came off well charged and not hot so something was working properly  ;)

Great resource here by HKJ, one of us.  :-*

I'm still using the Maha C9000 from a decade ago, so I don't know what's good value here in Australia. My next charger might be the SkyRC MC3000.
