A vehicle’s battery powers everything from the ignition to lighting when the engine isn’t running. Proper maintenance keeps batteries working optimally, preventing being stranded with a dead unit. Learn the best practices regarding battery basics, testing, replacement, and care for peak performance. To that end, employ these tips to enhance reliability and extend service life of this crucial component.
Understanding Battery Function
Lead-acid batteries feature lead plates submerged in sulfuric acid within a sturdy plastic casing. Complex chemical reactions between the lead and acid generate and store electrical energy when engines run. This stored electricity then powers key functions like starting, lighting, and ignition when the vehicle is off. Nonetheless, batteries gradually lose their ability to hold a maximum charge over time.
Inspecting Connections
Battery terminal corrosion or loose connections trigger starting problems, flickering lights, and electrical gremlins. Use a wire brush to remove any white, green, or blue crusty buildup on connections. Reconnect tightly and apply a corrosion-fighting spray afterwards as added protection. Repeat cleaning every six months, especially in ocean climates promoting heavy corrosion. Faulty grounds also affect performance negatively, so check chassis connection integrity.
Testing and Monitoring
Portable battery load tester
While appearance clues indicate battery age and coarse connections, only testing confirms whether yours holds a proper charge. Portable battery load testers connect via the terminals to diagnose remaining capacity and output, according to the folk at Clore Automotive. Advanced models perform automated multi-point inspections delivering pass/fail verdicts on battery fitness. Conduct testing annually once your battery passes 36 months old regardless of appearance or symptoms. Earlier and more frequent assessments work better for vehicles subjected to extreme hot/cold operation.
Voltage warnings
Modern cars have sophisticated voltage monitoring systems providing early failure warnings. Battery light illuminations, stuttering electronics, or error messages during operation likely indicate capacity issues before no-start conditions happen. Heed these warnings promptly and pursue formal testing to figure out if replacement becomes necessary. Catching problems early on avoids being stranded roadside later.
Replacement Intervals
Hot climate degradation
Sustained heat exposure above 90°F degrades lead-acid batteries quicker than lower temperatures. Expect closer to a 3-year average lifespan for warm environments like the southern or western U.S. Cooler northern tier locales may see up to 5 years from a well-maintained unit. Vehicle usage also plays a role, with frequent short trips and extreme stop/go duty shortening usable life substantially.
Aftermarket vs OEM units
Seeking savings prompts many owners to replace failed batteries with cheaper aftermarket models. Nevertheless, sticking with original equipment manufacturer (OEM) approved units typically delivers longer service. OEM batteries feature better warranties against premature failure, with pro-rata terms reducing replacement costs if problems develop earlier than expected.
Maintenance and Care
Keep it clean
Prevent future connection troubles and maximize battery lifespan by keeping your unit’s plastic case and terminals clean. Wash surfaces every six months with diluted baking soda/water when inspecting cables. Rinse residue away using plain water afterwards. Then dry completely with a clean shop towel prior to reconnecting terminals.
Avoid deep discharging
Attempting to restart a vehicle continuously with a weak battery worsens its condition through deep power depletion past safe margins. Refrain from grinding the starter motor endlessly during cold weather or when capacity drops because of age. Car battery jump-starting or recharging works better for iffy situations until swapping in fresh replacement battery.
Conclusion
Monitoring battery age, testing capacity annually, and maintaining clean connections guarantees optimal performance from these crucial components. Assist lifespan through proper care during storage periods or extreme usage conditions. Employ the guidance in this piece so your vehicle battery exceeds design expectations. Then expect reliable operation with no untimely failures stranding your travels.
