I have 48 of the 2000mah eneloops used in various remotes, controllers, mice, keyboards, etc and they all last an extremely long time and none have died or given me issues so far. Here are some stats on Eneloops:

2000mAh seem to be the best deal. >3 Times the life cycles and only 1/5 less charge than the 2550mAh.

If the batteries magically didn't lose charge capacity (all batteries lose capacity with use/age) and always reached maximum charge cycles (charge cycles are averages):

Maximum lifetime mAh:

lc = life cycles (recharge cycles)

2000mAh max x 1800 max lc = ~3,600,000mAh max

1000mAh max x 2000 max lc = ~2,000,000mAh max

2550mAh max x 500 max lc = ~1,275,000mAh max

Minimum lifetime mAh:

1900mAh min x 1800 max lc = ~3,420,000mAh min

900mAh min x 2000 max lc = ~1,800,000mAh min

2450mAh max x 500 max lc = ~1,225,000mAh min

Average lifetime mAh:

1950mAh avg x 1800 max lc = ~3,510,000mAh avg

950mAh avg x 2000 max lc = ~1,900,000mAh avg

2500mAh avg x 500 max lc = ~1,250,000mAh avg


So with the 2000mAh battieres you get more mAh max (milliampere-hour or more simply a higher max useable quantity of power) over the life of the battery. You will have to recharge a little more often than the 2550mAh (about 20% sooner) but the battery will last for >3 times as many charge cycles and >3 times the mAh power over it's lifetime. Meaning you get 3 times the gameplay out of the battery before full replacement at 2/3 of the financial cost.

In other words go with the 2000mAh AA seen here. I wouldn't go with the XX unless your only concern is maximum time between charges regardless of shorter recharge quantity, larger cost, and shorter mAh life.

This is the pack I bought.

Edit: For a recharger I bought 2 of these years ago. I was using energizers at that point but most of them have dropped dead (cheaper energizer rechargeables are crap imho. The charger is a smart charger though so it does a decent job with the eneloops.

Wonderful device. I have a tip though if you are interested.

I highly recommend getting a set of these as well.

Powerex 2700 mAh

And a fast charger


You see a lot of complaints of people not getting a good enough draw from the MFLB. It comes with a set of 2 slow charge NiMH batteries (I believe the brand is Eneloop, unless they have changed it) which are nice because the charge lasts weeks to months but they take hours to charge and have a lower capacity. The higher capacity batteries can be charged in 15 minutes (with the right charger) and give you a quicker heat time so you can get a better draw.


Two warnings: You will have to peel off the plastic lining on the batteries to use them this way and do not mix up the chargers. The fast charger can destroy the slow charge batteries. You can get a smart charger to avoid having to worry about this.


tldr: The batteries it comes with work just fine, but I have had better results with these ones.


Enjoy :)

Energizer pack that comes with 4

---

^^i'm ^^a ^^friendly bot

I have 4 rechargeable AA's and 4 rechargeable AAA's, why are you buying disposable batteries? Chargables and the chargers are very cheap.


http://www.amazon.com/Energizer-CHP4WB4-Recharge-Charger-Batteries/dp/B003SP4QAE/ref=sr_1_1?ie=UTF8&qid=1382645693&sr=8-1&keywords=rechargeable+battery+kit

If you're fine with a $20 face cover (I'm a savage on a budget, tyvm) I'd recommend rechargable AA batteries for the Touch controllers. I got an Energizer pack that comes with 4 so you could theoretically keep 2 in the charger at all times while you're using up the other 2.

And why is it a bad idea to keep them in the controllers? I assume in case they leak, right? but that seems like a strange warning since I have dozens of peripherals and I keep batteries in all of them unless I shelve them for long periods. Is there another reason?

Thanks! One more question about the Wii remote batteries...do most people just buy rechargeable batteries and swap them in and out (charger like this: http://www.amazon.com/Energizer-Rechargeable-Charger-Batteries-Included/dp/B003SP4QAE)? I'm used to just being able to plug in the micro or mini USB cable for the PS4/PS3.

Yep those should work fine. I'm not entirely sure about the charger. It'll probably work though. The ones I ordered came with a charger, sort of like this one: http://www.amazon.com/Energizer-CHP4WB4-Recharge-Charger-Batteries/dp/B003SP4QAE/ref=sr_1_5?ie=UTF8&qid=1397232002&sr=8-5&keywords=energizer+rechargeable+batteries

edit: just saw Amazon doesn't ship to Brazil, but I'm sure you can find some energizers sold with the charger out there somewhere.
