battery is like a piggy bank. If you keep taking out and putting nothing back you soon will have nothing. Present day chassis battery power requirements are huge. Consider today’s vehicle and all the electrical devices that must be supplied. All these electronics require a source of reliable power, and poor battery condition can cause expensive electronic component failure. Did you know that the average auto has 11 pounds of wire in the electrical system? Look at RVs and boats with all the electrical gadgets that require power. It was not long ago when trailers or motor homes had only a single 12-volt house battery. Today it is standard to have two or more house batteries powering inverters up to 4000 watts.
Average battery life has become shorter as energy requirements have increased. Life span depends on usage; 6 months to 48 months, yet only 30% of all batteries actually reach the 48-month mark. You can extend your battery life by hooking it up to a solar charger during the off months.
