Battery only year old but says service battery

My brother installed a battery from ifixit a little over a year ago in my MacBook air. Its been working fine for the past year but recently been holding less charge. The battery is now only lasting a few hours for each charge and says service battery. It only has 361 cycles on it and I only charge when it 2%. I really don’t have the money for a new battery is there any way to fix it. I thought it would last at least a few years.

here are the results

Go ahead and try calibrating it and then run the Coconut again. You sure have a lot of cycles for only the short time you've had the new battery.
