If you really never use it just unplug the battery from the motherboard... Run it to about 40-50% first. Hook it back up to cycle twice a year or so is also good. It's bad to leave lithium batteries too full or too empty for long periods of time. In fact, my sony phone has a feature called battery care that prevents leaving a full battery overnight https://www.sonymobile.com/us/xperia/technologies/battery/ Lenovo power manager also lets you set charger start and stop level on my thinkpads, but there is no feature like this for razer. Maybe some windows program will do it, but these tend to work poorly and only when the PC is booted up.
