As some one who comes across stranded motorist on a semi common experience, a few pre broken down pointers. Up grade to the largest battery the self will hold. Many cars/trucks have under sized batteries and all those electrical gadgets are killing them. Next up grade that bigger battery to an AGM, shorted dead cells are nearly impossible to create. They’ll deep cycle hundreds of times. These batteries have huge reserves but need to be sure it’s got the needed cold cranking amps. These batteries have a 5-8 year life and are in many emergency vehicles. In the auto stores there often the Gold or Platinum series. At Bass Pro or Cabela’s in the boating section.
