Re: Test/Review of Sanyo 18650 2600mAh (Red)

btw, are they li-co or advanced chemistry?

I got mine very recently (See date in info box), but I do not know how long time they have been stored in different warehouses before that.

There it not any obvious print on the cells, as can be seen on the pictures.
In the red plastic there is some engraved tiny letters: "SANYO L" and "UR18650FM R1122"
Under the red wrapper, there is some print directly on the cell: "PJKM4PE" and "135836"
Note: The text is very difficult to read, i.e. I might have a letter or number wrong.

you think these cells are good for repacking laptop batteries?

Re: Test/Review of Sanyo 18650 2600mAh (Red)
HI HKJ,
I was reading your charts that compare all of the 18650 cells with one another. I am a little confused about some of the labeling in the charts thought.
The chard shows this cell which performed well "sanyo 2600mah Red" Then right below it another cell that says "sanyo 2600mah Red BV" that perfomed only half as well under a 5 amp load.
What is the difference? Whats BV?
I am also not clear on what many of the other letters after the cell description are, like
SB, LB??? I can guess at a few like FT is flat top? BT is button top?
Thanks again for all your work on these.

It would be good if you went to that thread and asked the question. It is sort of OT here.

Protected or unprotected.

I can only have the same name once in my test, this means I have to add something to the name when testing more copies of the same battery.
Usual it is some letters from the dealers name, but if the batteries are from the same dealer I have to use something else like bt and ft (button/flat top).

The battery top exist in 3 styles: Small diameter Button top, Large diameter Button top, and flat.
