for everyone else, OP included, Rice has set up a perfect example for why i use eneloops, lithiums, and standard NiMH batteries (though i predict that baka-chan would then tell me never to mix batteries....)
To PentaxPZ:
Originally posted by RiceHigh Digital DSLRs and rechargeables are not two separate things IMO.
I'm sure rice believes "Digital Digital Single Lens Reflex" cameras have internal batteries that don't come out. this is wrong. all DSLR batteries are removable. Actually, i've yet to see a decent still camera (SLR or otherwise) that doesn't have a removable battery
Now, i do use my camera almost every single day. i may take 1, 2, 5, 20, 100, 15 or no shots with it. but if i want to use it, i don't want to have to wait to charge my batteries. the Lithium AA batteries means that it's ready to shoot when i want it. for play, testing, impromptu shots, documentation. whatever the reason, the Lithium batteries means i can pick up my camera whenever i want and shoot.....

..... however, on the 28th & 29th, i have a photoshoot. it's a date set in stone. this is when i swap out the Lithiums, and use NiMH batteries for the whole day.
If I know there's going to be a shoot "on a specific day". i recharge my NiMH batteries the day/night before, use them on that day, then put them back in other AA stuff i use (flashes mainly), and the Lithiums go back into the camera. It's like charging any other camera's battery before something like a wedding or a birthday party, or something like that.
Originally posted by RiceHigh Eneloops do NOT have any lithium advantages, no matter in terms of weight nor adequate voltage and power delivered.
I am, however, lazy sometimes. when i do run out of charge on my Lithium batteries (this generally happens with an impromtpu photoshoot, which my friends love springing on me.
) a set of 4 charged eneloops are always in my camera bag for backup. They're also in my flash as i don't always use that. the great thing about eneloops is that they lose so little battery charge over time, unlike standard NiMH AAs that will be at no charge at the end of the month. they don't give me as much power, partially because they're not as powerful, and partially because they have discharged a little over time. but it's generally enough to get me through the shoot and until i have time to go to the shops to get a new set of Lithiums
But that's just me
If, however, you wanted to have the convenience of being able to shoot whenever you like and not worry too much about battery self drain (Standard NiMH), Lack of shots (Alkaline), adding to the waste problem (Lithiums) and the cost problem of buying disposable batteries time and time again (Lithiums and Alkaline), Eneloops are great. Keep a charged set in your camera. it'll be ready for you when you do use your camera. you don't have to wait to recharge the batteries because they've discharged over a short time.
For the record, the only thing that rice was right about is that NiMH is a little heavier than Lithium batteries. How much heavier?
My Sanyo 2700mAH batteries weight 116 grams and my Energiser Lithium AAs are 56 grams. Are you really going to notice 60 grams? on a 1.45 Kilogram setup (*ist DS + Tamron 18-200+ AF540FGZ), i don't. Alkalines are, for the record, 90 grams...
