@mohdafzal40548 all of this will depend on where you bought the battery from. We really can't speak about RMA or even the quality of the battery. You may need to contact the original seller for that. Remember, they are one of the biggest commodities that are being counterfeited right now.
Since we do not know which OS you are using, we are assuming it is a Windows version of some kind. Let us know what you are using so we can tell you how to run the battery report. It may or may not be different then what you are getting from your software. Remember that all of this will depend how often you use the battery and the more you use it, the more it will degrade.
You also want to go ahead and calibrate your battery, so that you do get the accurate information from it. Something [https://www.howtogeek.com/172271/how-to-calibrate-your-laptops-battery-for-accurate-battery-life-estimates/|like this] should work for your computer as well.
