Won't start

Sounds like bad or dead battery, bad battery or starter connections. Start there.

Charge battery but also check your starter solenoid. Clean your electrical connections. Check for corrosion on terminals/ cable connections. Pour coke if necessary. Soda will eat corrosion. Apply a good splash of Vaseline afterwards. Apply weekly or as need. Vaseline melts in heat yes so that's why we check under the hood for the basics. Put that one on your basic checklist. Stay on top of things, less issues
