If you need to use it for an emergency, you can always charge it for as long as you can and use it. A higher capacity merely indicates the maximum power it can store, and hence the maximum time required for full charge which is higher, but you can always quarter or half charge it and use it to meet your needs. Granted, half-charging your rechargeables repeatedly can be damaging for them. :) Just to point out that having a larger mAh will not require you to always charge for 24hrs.

I've been using their battery packs in two-way radios for years and they've been very good. Maha has a new product out called Imedion that claims ultra-low self-discharge, but I haven't tried them yet. They also have 11,000 mAH D cells if you're looking for capacity. Sony's "Stamina" AAs are pretty good, too. And you're right, Troy: I have a fistful of Duracell/Energizer AAs and AAAs. They're great for about 25 cycles and and blow chunks after that. --Mark Try Maha/Powerex. I’ve been using their battery packs in two-way radios for years and they’ve been very good.

Who makes quality batteries? Please let me know for i would like to start purchasing thier batteries. Ok,

NiMH cells don't trickle-charge well. In fact, most mfg's like sanyo and gold peak actively discourage trickle charging in favor of a dV/t terminated fast charge. Also, from what i've seen, most products that take "D" cells, and there aren't many anymore, require 4 to 8 batteries. Four tenergy D batteries go for about 50 dollars. Not many people are smart enough to realize that it's not a bad deal, and a good portion of the rest simply can't afford it. Not many people are willing to put 50 bucks in batteries in a flashlight. Hell, "D" batteries aren't even common for OEM purposes. Even EV's and stuff use SubC. Energizer D rechargeables are really mostly just legacy support. In addition to the above:

However, two problembs bubble up. According to Amazon, two Energizer D NiMH cost $12.87. Four Energizer AA NiMH cost $12.00. All of them are composed of the exact same 2500 mAh cell. This follows your guides of production, the D's and the AA's are made of the same cell off the same assembly line using the same tech and the same R&D etc. The price is not even close, basically 2x for the D's. Secondly, as you point out they perform terrible in flashlights because of discharge problem. So basically, once the consumer wastes their $12.87 and finds they don't work very well in their flashlight they can throw them away and buy regular alkalines again. Basically, Energizer should not sell D rechargeables because they are a bad product to begin with. This is my spin on that logic, I love rechargables myself, in everything.
