Hey Ashley, great choice with the SigmasTek SP12-7.5! When installing the battery, ensure the system is powered off, and follow the manufacturer’s guidelines for proper connection – typically red to positive (+) and black to negative (-). Double-check the voltage matches your system requirements, and securely fasten the terminals. Once connected, power up the system and perform a function test. Don’t forget to document the installation date for future reference. If you have any concerns during the process, feel free to reach out!
