Tldr: can anyone confirm which pin in the battery is pos/neg for a manual "jump start"?

I bought a used lymow one that was advertised as having a bad battery. The seller said the battery will not charge in the mower, but will manually.

Based on my research of the charging system (after the fact unfortunately), I'm second guessing that a battery that can be manually charged would be the issue in on board charging. So wanting to test before buying a new battery.

To start I need to charge the battery. I'll also test the charge system with a multimeter to see if I can find a different point of failure.
