Hey Roger,
When disconnecting a battery it is always recommended to disconnect the negative terminal first. You'll want to make sure the vehicle is off and locate the battery. Typically is is a 10mm wrench on most batteries, you can use that to disconnect the negative terminal. After that you will just follow the instructions for the disconnect depending on what brand or model you got and install as the instructions say.
The Blazer EV is a little different so let me know if you have the EV trim and I can walk you through that.
