Fits and works well so far.
Shipped about 80% charged. Dimensions were as described, just soldered on my old connector. Seems to work well in my Autel TS501 scanner. Good upgrade from the original 3000 mAH battery which was giving me problems.

mooie vervanging
Goed product maar wel opletten dat je de versie met of zonder electronica aan de + en - draden bestelt, volgens vereiste van toepassing.

Working well!
I bought this battery to replace the one in my Keychron K2 Keyboard. Unfortunately, the connector was not plug-n-play. After cutting off the connectors and re-soldering , the batter is working great. I can go several days of heavy use without having to recharge. Make sure you know what style of connector you need to avoid having to solder the connector. You may be able to find a battery that is plug-n-play. Still, I am happy with my purchase.
