i think this is the model # Model: 30041-0. (on the amazon webpage i clicked "See more technical details" and that's where i got the model number) i did a quick google and that led me to this page http://cgi.ebay.com/Li-Ion-SANYO-18650-3-7V-2-8Ah-2800mAh-Cell-30041-0-/330522127829#vi-desc and that page has a .pdf with specs for the battery wich is here http://www.all-battery.com/datasheet/30041-0_UR18650ZT.pdf and i noticed is says ZT there. thanks for the tip.

Well this is the specific model 3UR18650SAX-BDA. If it does not say that specifically, then it's not going to be the same chemical makeup.

Why is there 5 posts?
Does this battery have the protective electronic like the DC9180?

is this a ZT battery http://www.amazon.com/Li-ion-Cylindrical-2800mAh-Rechargeable-Battery/dp/B004JPSS1K/ref=sr_1_fkmr1_3?ie=UTF8&qid=1307460687&sr=8-3-fkmr1 if it is i may grab some and upgrade my pack to see if there is anything gained.


It will not be an upgrade unless you want to drill 1/8" holes for a day. Cant supply high current.

I see what you are saying... I am new to understanding this technology. I read this the other day...



and this...

**Abundant variety of models meet wide variety of uses(UR18650 series)

>F: High capacity with steady operating voltage model.

>E: High current model for power applications.

>Y and A: Cost performance and improved standard model by optimization of material.

>L: Cost performance and robust model by optimization of material.

>SA and W: Excellent power model for power tools by optimization of material and structure.

>U: Long storage life and high current model.

>ZT: Neo hybrid positive electrode enables higher charging voltage, which realizes further high capacity model.

so I'm guessing these SAX batteries are already putting 20A draws continuous. Although, now that I think about it, what would those ZT batteries do for the longevity of the flash light that use this batt. Pack? From what I have noticed, my flash light dies faster than my drill... well, I work in dark places  and use the flash light mostly continuously... i'm guessing the flashlight does not need high power but more of high capacity batteries.

So what if I upgrade one pack with ZTs for the flashlight and A123 APR18650M1 for the drill?

When deconstructing this battery did anyone check what the five contacts are for?

I am actually going to use these for an outside project, and I am working on my design.
