Without knowing the history, Panasonic.

Re: Which of these 2 used Lenovo batteries is the better pic
Again unless you know the history, I would not trust cycle count. It can be deceptive. A laptop always attached to an external dock and never ever allowed to discharge or discharged a bit then recharge again in a very hot environment is not good. That's only a few scenario of many.
What I would look for is age (about the same), remaining capacity (about the same but Pany is 6 months newer), manufacturer (prefer Panasonic), and history (unknown). So given those options, I'd say Pany.

You can't beat'em
Look at these figures, for a bunch that I bought in one lot earlier this year (most of them already sold with FrankenPads)
