That is a suitable replacement. It is a simple pouch battery with an easy connector so the actual physical work to replace it is fairly simple and the cost is very low for the convenience of using your system for long hours. It should also prolong the life of your laptop delaying replacement for a fairly long time.

The big question is about the quality of the internals of the battery. Is the material consistently folded? Are there overhangs or under hangs? Are there areas where the anode and cathode are close and will short in a few years of usage? I honestly don’t know how to actually check for this.
