Anyone have tutorial or pics on how to harvest cells from laptop batts?

Yep, right on both. Tabs are welded, not soldered, and those are temp sensors for the pack. What brand is the laptop? Those are some clean cells…

The laptop was I think a Toshiba. Older, not even dual core. Ive had the pack for maybe 2yrs now. She bought it as the old one was not holding charge, but then decided she was due a new laptop anyway (got herself an i5) so the pack never saw any service, at least not much, maybe a month.

The replacement pack is a ‘2 power’ brand going off the cardboard box it came in.

Are they safe tech? I assume they are no longer protected.

Edit: and they test at 2@1.6v, 2@1.8Xv and 2@1.9Xv. Interesting how they appear to be in pairs.

They will be unprotected cells (all laptop pulls are).

Note: clip one wire at a time. These half-charged batteries can produce a surprisingly powerful arc if you try to cut 2 simultaneously

This was the mistake I was making. I was doing quick, deliberate cuts but still once and a while getting a spark when I made the cut. After that I started paying attention to how they were wired together
