Looking for highest capacity NiMH AAA's

[JimH]

What are the highest actual capacity (as apposed to advertised) AAA NiMH batteries. Low self-discharge is not a consideration - the batteries will be recharged frequently. I'm looking to upgrade the AAA NiMH batteries in my Coleman Quad LED Lantern. The lantern comes stock with 3 X 600 mAh AAA NiMH batteries in each of the four removable modules.

That page says it runs off D cells - I'm guessing it charges 3 AAA cells in each little peel-off module from those D cells? If there's space, go for AAs - they're about 2.5x the capacity. With that said, few AAAs will have an actual capacity far over 800 mAh.

Battery Junction is a popular choice for stuff these days.

Correct

No space for AA's. AAA's are easily replaced - no wiring or soldering required.

I would try and get some duraloops for it, that way you wouldn't be fighting the self disharge of non LSD nimh cells constantly. The capacity may be less but all the high capacity AAAs I have here (energizer, rayovac non LSD, kodak) discharge almost completely after a week to a few months while my duraloops and rayovac hybrids only need to be charged when I drain them. I have generic green sleeved nimh AAAs 550/650ma that hold a charge longer than all my non LSD nimh AAAs.

Thanks, Bill. The thread is over 3 years old, but it looks like Sanyo 1000's would be a good bet. I was kind of leaning that direction anyway.

Jim, I have more experince with AA cells than AAA cells, but just the same I have worked with Sanyo 900 and 1000mAh cells. Between the two I have to say that the 900's are/were a better cell. Initially, yes, the 1000's do have a bit more capacity. Down the road however, the 900's end up holding up better.

Then there are the eneloop AAA's. Again, initially they are very slightly less in capacity than the 900's. With these cells though (the eneloop's) it doesn't take long before they actually have the same, or even more capacity than the two higher capacity cells. I use my AAA cells hard, with up to 2A loads at times. This may be why I'm seeing what I see, but in my experience, after 10-20 cycles, you'd be ahead to just go with the eneloop AAA's.
