I cannot find any up-to-date info on the best batteries out there at the moment.

I have found some positive reviews of the Energizer 2500 mAh batteries, someone recommended the Uniross 2700's

Is there anything better?

By the looks of things I will also need an intelligent charger, that decharges the batteries first then trickle charges them and automatically knocks off charging when the batteries are at full capacity? Any charger recommendations?

Thanks... I will be charging 4 batteries at a time btw...
 
You can recharge non-rechargable batteries, waste of money buying rechargable ones if you ask me, let alone expensive ones.
 
my Uniross Hybrios are excellent batteries, they hardly lose theyre charge over time and have a high capacity

What a load of crap, Normal AA batteries wont last nowhere near aslong as a good set of 2500-2700 ni-mh.
 
They do last quite a while though. I was always under the impression it wasn't possible to recharge non-rechargables. Until we got some new fangled charger at work, which has been recharging our non-chargables for over a year and a half so far alongside our Nimh's.

RS Components also have a make of rechargable that suffers from no memory effect, which has been an issue at work for the past few months. Those buggers work nicely.
 
They will be used with camera equipment such as flashes. They may have a couple of weeks between use....And so it is fairly important that they hold their charge.

Just been doing a little more research and have found both the;

Sanyo Eneloop NiMH AA 2000mAh

and

Uniross HYBRIO AA Ni-MH 2100

will both hold their charge for a prolonged period.

What about chargers? any recommendations?
 
Sorry for the battery n00b question: But does more "mAh" = longer use before depletion?

I'm following this thread because my HTPC keyboard takes four AA batteries, so I need lengthy use.
 
Best rechargeable AA batteries are ones manufactured by Sanyo this is fact, 2700mah currently highest. They're rebadged and sold as duracell 2650mah as well some other no name makes but I can't remember at them moment, still I would buy the sanyo branded ones.

If the batteries are going to be left standing any amount of time then get some of the new low self-discharge batteries, most companies offer these now all at very similar capacities. Again I would go with Sanyo eneloops they tend to have a lower internal resistance.

Chargers are like for like unless you want to spend a bit and get a proper DCD, the chepest of there kind I know of is £18, this has an lcd and will tell you battery capacities, test them, refresh them etc etc. It's branded as 'Angeleyes' but I can;t tell you where to get it as per forum rules.

Oh and lol at the recharge normal battery comment, just so wrong, yes you can do this but there are so many reasons not too I'm not even going to get in to it!

Yes, it's a measure of how much current it can supply for one hour.

There is proof it works, thats all a battery needs to do isnt it? Anymore effort and you're as enthusiastic and slighty sad as the guy in the video is pretending to be over batteries.

Of course this is just my opinion and a radical suggestion to the OP, I didnt mean to hurt your feelings.
 
Whatever you do, don't get one of the manual/timer chargers ie. £5-£10 including batteries.
Get an "intelligent" / -dV cutoff one. The Maha c9000 is apparently good (£50 though). I got a Vapextech VTE 4000 for about £20, does 4 batteries in 32 mins, has a fan to keep batteries cool.
Sometimes they get warm/mildly hot but i just leave them on till the charger cuts the fan off (5 mins after they are done) to cool them down.

Cells get hot if you charge them fast, and -dV can sometimes result in overcharge, but at £5 for 4 AA's, who cares if it shortens the life a bit?

JAMAL said they won;t have anywhere near the capacity not that you can't do it, and he is quite correct.

Not to mention that alky's are totally unsuitable for any kind of high ampage application.
