e-Electric Batteries & Chargers > odd sized Lithiums? Chargable? How? =)

I've found a few different Lithium batteries that were odd sizes. One I found was actually made by Energizer. They have AA batteries that are Lithium (or at least it says lithium on the package and says it lasts 4 times longer then normal batteries which would make sense if they were in fact lithium). The thing that doesn't make sense is that since they are AA batteries, they would be the standard 1.5v. I thought you can't get less than a single cell which is 3.7v...

How is it that they are able to make them 1.5v, and is there any way to charge them? I have a Triton 2 charger, so it's capable of every battery type imaginable, but it goes by how many cells in the pack, and calculates voltage based on number of cells, so if 1 cell is the lowest it goes, I'd blow the battery up =P

The other batteries I was wondering about recharging is the small batteries like watch batteries etc.. They say 3v, not 3.7v on them, and all of them say "Do Not Recharge" which I can understand them putting that on for the morons who'd use a regular el-cheapo battery charger to try and charge them. Would I be able to successfully charge those with my charger however? Are they actually 3.7v but just labeled as 3v? What's the deal?

Ok, I'll try. First, are you sure of what you are calling "lithium"? There are several battery types that are in the lithium family, but are not necessarily rechargeable. The rechargeable ones are specifically marked as such. Don't try to recharge a standard lithium cell. Bad things can happen. As far as I know, the only types that are rechargeable are "lithium-manganoxid", "lithium-ion" and "lithium-polymer". There may be others, but I'm not an expert. I don't think the ones you mentioned are rechargeable but even if they are, they're probably 1.2 volts per cell, not 1.5 vpc. I wouldn't bother messing with them. Stick with what everybody else is using. Just my 2 cents.

well for standard AA batteries, I'm using NiMh for all of my stuff so I can recharge them as I go through them quickly (having 8 or so staff each with mini mag lights being used every day tends to burn batteries quickly). Using the NiMh works ok, but I thought if I could get the lithiums, they'd be even better for the job. I'd like to eventually switch over to using LED lights, but they are a bit bright for the job which would cause more distraction to other guests, and they don't come cheap...
