new replacement battery

So my macbook was randomly shutting off on its own at like 15-20% with no warning so I called Apple and received a replacement battery. I just checked coconutbattery and it says it's current battery capacity is now 100% while my other one was at like 60%. And the battery-loadcycle is at 1. My question is, what can I do starting now to preserve this new battery? I already plugged it in the moment I got it. My last battery had over 300-something battery loadcycles and would last for maybe a little over 2 hours. Thank you!
