Which NIMH rechargable batteries should I buy?

I need about 20 AAA, and 10 AA NIMH batteries, plus two chargers (I'm splitting the order with someone). What are the good brands and what's the best deal on them for around the amount I need?
Seems many people here use batteryspace and thomasdistributing. Which is best?
 
You don't wanna know.

I picked up a 4pk of Energizer AA 2300mAh for $9. Unfortunately the slow charger I have takes about 15hrs to recharge them.

Energizer is making 2300mAh's now?

Link?

Could be a good deal, assuming they're as good as their 1800mAh ones.

And.. that's not a bad thing. Fast charging = heat = shorter battery life = bad. 😉

I always have my C401-FS set to slow charge.
 
Target had them on sale last week. Oddly enough the Energizer 2100mAh were the same price.

I also saw the Energizer AA 2300mAh 8 pack for $19 @ Wal-Mart.
 
I bought some of those 2300 ones. Can someone sort of sidetrack on this thread and explain to me the difference between 2100 and 2300 in technical terms?
 
Quite simply, it is how much power the battery holds.

A 1800mAh battery should theoretically be able to put out 1800 milliamps(mA), or 1.8A, for an hour, hence 1800milliamp-hours(mAh).

A 2300mAh battery should be able to put out 2300mAh, or 2.3A, for an hour.

Or 1150mA for 2 hours. Or 575mA for 3 hours... etc.

Of course, when you connect multiple batteries together in series, the capacity raises with each additional battery. So if your camera takes 4 batteries and you use the 2300mAh flavor, you have a total of 9200mAh available, compared to only 7200 with 1800mAh batteries.

Not really sure if that does a very good job of explaining exactly what it is, if you don't have a concept of amperage/current.. but.. if not, go read some basic electronics.. lol.

Edit: grammar, corrected abbreviations..lol

Nope, that makes sense to me. Thanks Eli.
 
because the larger the mah rating the more charge that is stored and the longer the battery will last
in the same current draw situation.

and thomas-distributing is a great place to get them.

I thought they used to have different combination/larger quantity sets? Now all I see in powerex are packs of 4.

And whats the best deal on a charger? I'd rather not have a 15hr charger, but don't need a 1hr either. All I know is that the best chargers charge each battery until it's charged, then turns off. Whereas others charge them all a certain preset amount of time, which may overcharge or undercharge the batteries. Aren't some of the ones at Walmart/Target like the latter?

BTW, this says rapid charging isn't always bad.

I think that technically when you run them in series your volts will increase by 4 (with 4 batteries), but your capacity (amps) will stay the same. So you'll now have 6 volts at 2300mah vs. 1800 and 1.5 volt with one battery. Now, if you run them parallel you will keep the same volts but quadruple the longevity of the battery, since you've got four times the amps! Or something.
