These are the first set of batteries I got from 18sixfifty…they work GREAT and every light I put them in run like a champ…of course I only run them in my “daily driver” lights at around 3~ max
Sure would extra mAh be nice…but if you can get em dirt cheap go for it!
The ones with the blue ring around the + connector are 2600mAh and work just as well
The price for these are good and they’re listed as genuine and new. Only thing that concerns me is they’re for a model which is very dated now. It’s for an Acer TravelMate 3200 which is from 2004. So these batteries are at beast from around 2005/6? That would make them pretty old. What do you guys think?
Just pulled appart a Fujitsu Siemens pack BTP-C1K8 , 11.1v 4400 mAh
It came from a defect lapop, probably main board defect. (wouldn’t turn on)
it contains 6 cells, Sanyo UR18650FJ, they are 2200mAh
The sanyo labeling is very difficult to see at first, the clearly printed info on the cells lead to nothing
All 6 read 3.8v after separating.
Kept 4 out of 6, 2 of them were dented on the side and bottom.
This was a new, never been used pack that I was able to tear open with my bare hands. Either I’m turning into a monster or this was an exceptionally easy pack to open.
All 6 Samsung 26D cells were sitting at 2.9V and are charging now. I have no reason to think that they won’t charge up to just slightly lower than their rated capacity of 2600 mAh.
Last week I got a Dell battery back (here: http://www.amazon.com/gp/product/B000WDRXL4/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1)
It had six light-blue/green colored cells in it, no brand name on the wrapper - just a bunch of numbers. Look similar to the LG's in #2 in the OP.
All six tested to 3.88-3.89 volts on my multimeter. I have no means of testing capacity at the moment. I figure the cells have to be pretty new to test with that high of a voltage right?
