| Do AA Lithium batteries leak like the alkaline batteries do ? Also where's a good place to order some where the chance of counterfeit is low ? |

I'm assuming you mean the standard AA voltage and not the higher 3.7 volt lithium ion batteries (14500)? Despite the cost, I use ithium batteries, either CR123, AA or AAA for mission equipment applications, self-defense tools or when backpacking. Lithium batteries (in general as there are several different chemical variations) don't leak. Unprotected cells can heat up and explode or catch on fire, but those are extremely rare and often involve a defective cell.
Lithium batteries have a vastly longer shelf-life than alkaline; they are lighter and perform better in higher temperatures. For 90% of my battery needs, I rely on rechargeable LSD NiMH batteries. For serious tools and backpacking I almost always go with lithium batteries. ROCK6 |

Oops. Regular voltage . Battery Junction dot com had them in bulk quantities. Shelf life is up over 20 years now, making them the kings and their out of pack voltage is about 1.80v. They're about half the weight of alkalines. Here's a good review of the L91 Ultimate: Energizer L91 Lithium Ultimate AA 3Ah at a 1A draw is pretty impressive. Chris |

See above. Nimh doesn't either and is pretty much the safest chemistry out there. Costco had Eneloops $20 for 10 some time ago and one of the large name brand companies uses theirs rebranded IIRC. Fast charge capable. NiMH have a lower nominal voltage, 1.3V per cell as opposed to 1.6V for lithium AAs (alkaline 1.5V as a comparison.) NiMH are great rechargeables, much better than the old NiCADs, but the lower voltage can cause problems with some electronics. They also self discharge, so aren't good for storing. I keep Lithium AAs/AAAs for immediate use and NiMH for recharge and for backups when I can solar charge. I also use the lithiums in camping equipment, BOBs, GPS/Beacons, etc. And high dollar electronics like NODs and my Bosch laser level. I get Energizer lithium and NiMH AA/AAA batteries at the military commissary for about half of retail cost (I'm not sure of other deals out there). |

Fast charge capable. Fujitsu markets their own brand which is more, or less, identical to Panasonic's offerings. Duracell Ion Core AA/AAAs are pretty much sourced from the FDK plant (more akin to Eneloop XX/Pros), as well as some of the Amazon offerings, Ikea and Energizer 2300s, which are marked 'made in Japan'. There are some variations, but Fujitsu is selling to everybody and their grandmother. Chris |

I haven't tested the Eneloop 4th Generation batteries, but I've had their Low-Self-Discharge stored for well over year and work quite well. I could only estimate about 70-80%, but it wasn't too noticeable for intermittent use. ROCK6 I'll have to try some. |

Fifth Gen. Eneloops are 70% after 10 years, so there's no worry about that. Chris 1 year self discharge test: Eneloops, GP and Imedion... |

Thanks Chris. That's pretty amazing...70% after 10 years is phenomenal for a rechargeable! I won't even consider alkaline batteries anymore unless I'm on the trail and need an emergency replacement. Lithium or rechargeable (Li-ion or NiMH) are all I buy these days. ROCK6 Quoted:

Chris ROCK6 Fujitsu, Eneloops, hi-cap (semi-LSD: Eneloop Pros, Duracell Ion Core, Fujitsu/Amazon Hi-Caps) offerings, Amazon, Duracell, whatever, are ultimately the way to go. I'm at about 5+ years into my first batches of Eneloops and they're still in the 1.5x volt range for internal resistance on my Maha C9000, so they're good and my AAAs are a bit higher. Some of the better brands of HSD batteries, like my Sanyo 2700s, AccuPower 2900s and AccuPower 1200 AAAs have long since bitten the dust, so I won't be buying any of those. I do take out my batteries that don't get used much and run them through the Maha for a few cycles, to keep the electrolytes spread out, so that's always a good practice. Get an analyzing charger, like the Maha C9000, LaCrosse BC-700/1000, Opus BT 3100/3400, or Liitokala Lii 500 Engineer and a person can get an idea of the health of their NiMH and Li-Ion batteries and cells. I'm a bit more anal about it, than some, but I've mellowed over these five years, lol. Chris |

Battery junction allowed me to seriously stock up on the cr123a batteries over time. Free shipping and tiny coupons got me to place orders a couple times a year and over a few years I built up a nice stash.
Sam's is where I get the bulk packs of energizer lithium aa and now aaa batteries. If I don't go I ask an aunt to pic some up a couple times a year. They have mostly swapped over to these as well. My eneloops are the glitter ones from several years ago on clearance, I also agree with the maha charger. I guess I will shop new eneloops this holiday just to get some newer ones in and mess with them. Since I got rid of alkaline I really don't deal with batteries all that often. Kind of nice. |

I got two of them and they're the 9/2012 5th Anniversary jobbies and tested quite well out of the pack. I don't think that they've changed all that much from say Gen. 2 through Gen. 5, it's just like with Mountain House and LifeStraw, the products were new and they really didn't know how good they could be, or how long the shelf life is/was, so they guesstimated.

I have three Maha C9000 chargers to feed my ham radios and flashlights. Great charger.
All long term batteries are NIMH because I have lost too many electronics from alkaleaks. Have some lithium for extra long storage in emergency lanterns. Still use alkalines for short term use where I plan to use until exhausted and throw away for fear of leaking. |

Woot it was. Before amazon got ahold of em.
The aa have proven themselves so what I really will order will be aaa rechargeable. Should also get some decent 18650 batteries as well, got some cheap lights that came with junky batteries. I like to stagger lifetimes of stuff, so 4 aa will probably show up as well. |
