low cost high performance batteries
(OP)
What rechargeable battery type gives the most bang for the buck. I have a commercial product in need of a thin battery that can be worn on a belt clip, probably a 9 volt battery to power portable wearable electronics. The power consumption is 30-60 watts, so the units are used for only 1-10 minutes before battery recharge or replacement is needed.
Who's the best source for them in medium volume? 1000/month?
Thanks,

Sounds very painful, I can almost smell the burning flesh already...
Best bang for the buck is often good ole lead acid. There are gel cells that don't leak. I dimly recall flat lead acid cells (years ago).
Something more modern would be an off the shelf NiMH or Li-ion pack. Not cheap.

I'd prefer a flatter battery than AA if possible, especially when you add the battery holder. Although the long skinny form factor of six in a row may be useful, although a bit tricky.
VE1Bll, thanks,
I looked up Varta and asked for prices. They have a 3.7 V, 2 amp hour battery that's 0.5 x 1.5 x 2.5 inches size, not bad, not too heavy, 60 grams. The qty=6 NiMh AA math seems a bit better.

The definition of low cost, high performance, *non-rechargeable* batteries is still alkali batteries.
However as pointed out by VE1BLL lead acid are great batteries if you can stand the weight/size.
Li-Polymer are only for those who absolutely, positively, must have small and light. Like the product will not be viable with out them. Expensive!

all good input.
Is China the only option for purchase economically nowadays?
I'd guess yes if the volume is high enough.
