I use Energizer lithium metal batteries (not rechargeable Li ion batteries) in my equipment because they weigh so much less than other batteries. The motor grips in my both my 35 and my 645 take six batteries, plus my Sunpak 544 which also takes six. This makes for a huge difference in weight, especially when carrying multiple cameras. I noticed when I first switched over to Li that my motor drives were zippy as hell, though that could have been just the fact that the batteries were new. But I wanted to roughly test for any power difference, so I timed the recycle on my Sunpak when firing at full power, which was about 6 seconds. Then I loaded 6 new Duracell Ultra's into it and re-tested: 7.5-8 seconds.
I like Energizer Lithium', the only thing I noticed, which I heard beforehand is how they die all of a sudden instead of just slowing everything down. ( in motor drives )
Yep no surprise there. I most definitely wouldn't want to keep paying for them though. I'd rather take the speed hit and be able to recharge. Money better spent on equipment / enlargements, unless of course you're in the position to desperately need to quick cycle time.
Well the recycle time isn't even that big of a deal. I'm rarely shooting my 544 at full power anyway. What makes the difference is the weight. And for that I'm willing to pay.
In my SB-800, I use Energizer Lithiums. I got some rechargeable Li Ion batteries this weekend, but my Lithiums haven't died yet. And I'm not sure why I'm capitalizing things so liberally. Anyways, I use lithiums (there we go, proper capitalization), or have been using them, because the recycle times are noticeably better than regular batteries. But they were getting expensive, so now I'm gonna use the rechargeables, like I said. We'll see how that affects recycle time.
Oh, they totally do end up in landfills. Rechargeables are the most 'green' way to shoot I think. And aren't Energizer rechargeables cased in green? Is that like, their way of saying the batteries are the most eco-friendly?
Is there a difference between rechargeable and non-rechargeables in terms of battery life? Like, for one use of course.
My guess is that the non-rechargeable ones will last longer than rechargeable ones in the same device.
