Default Largest charger for AA batteries

Hi,

I'm have a bunch of cameras that take AA batteries, and I often need to charge these batteries all at once. I've seen chargers that can accomodate 8 batteries, are there chargers that can take more than? Does anyone have specific advice?

I've never seen one that done more than 8, but that doesn't mean they don't exist (obviously.)

Make sure that whatever you get has independent monitoring circuits for each battery. That way you won't have to worry about how much charge each one is starting at.

Here's one that does up to 10 cells at a time:

But the 8 battery charger is a lot cheaper:

A quick note from looking at those links.

You have to charge in pairs (2,4,6,8) in the smaller charger.
You can charge any number of batteries in the larger one.

This also (usually) means that the smaller one requires batteries which are as basically the same level of discharge. This is hard to guarrenty. I consider this a deal killer myself, but maybe you don't.

They are both fairly slow chargers. 10 hours for 1800mAh is kinda slow. But your goal is many at once, not amazingly fast.

Thanks for the tips. I'll probably go with the 8-battery models. I was really hoping to find some industrial type chargers that would do dozens, but I guess the solution is to buy a bunch of 8-battery units and string them up.

If you got so much batteries charged, won't you run out of memory-
cards before all batteries are empty?

I already can fill my 128mb card with pics and still have juice left
in my 1700mah batteries!

Ya, but there will be (many) more than 1 camera. I essentially need 2 sets for each.

The problem is that your memory cards might be non-volatile, but your batts are discharging when not in use. So you keep 1 set in the camera for instant action, then 2 sets on low trickle to guarantee that plug and play shoot. But if you're preparing the night before and you anticipate lots of flash, you might need space to charge 12 batts.

Consider chargers that can be connected to car batteries as well.
