Your car battery powers the electrical systems that run your accessories and start your engine. Over time, however, its capacity decreases due to constant discharge/recharge cycles causing some plates to wear away and reduce its capacity.
Most cars use lead-acid batteries. These contain plates made of lead and other materials immersed in an electrolyte solution; when the ignition switch is turned on, chemical reactions in the battery produce an immediate surge of electricity that revs the engine.
Battery Type
Your car battery is responsible for starting your engine, turning up the tunes, and activating rainy-day wipers. It creates electricity through a chemical process by converting individual lead plates into electrons that power your ignition and electrical systems – with an alternator charging it back up as you drive so it’s ready for its next start up!
Traditional lead-acid batteries contain an electrolyte of sulfuric acid and water that must be regularly checked and replenished to avoid dry-out, which shortens its lifespan. Modern low-maintenance technologies use alloy plate elements which reduce how much water decomposes during charging; as a result, inspections and topping-off are less frequent and inspections should take place less frequently.
An AGM battery (absorbed glass mat battery) uses a fiberglass mat between each cell to absorb and store electrolyte, without venting gases or leaking battery acid; they often offer superior performance and longevity compared to traditional FLA or EFB lead-acid batteries.
Modern high-performance cars and luxury vehicles often utilize lithium-ion batteries. These cells store energy using multiple lithium-cobalt cells and offer superior efficiency over conventional lead-acid batteries, in terms of weight reduction.
Furthermore, lithium-ion batteries offer longer lifespans than their traditional counterparts making them an excellent option for drivers taking long trips across mountainous terrain.
Battery Maintenance
A battery produces electricity by means of chemical reactions within each individual cell. Lead plates interact with an electrolyte solution to generate electrons that power your car’s ignition system and start its engine. However, over time these chemicals deteriorate and lead to the loss of its ability to hold charge in your battery’s cells – eventually depleting your charge permanently and necessitating replacement.
Dead batteries can leave you stranded on the side of the road, so proper battery maintenance is crucial in order to avoid costly and inconvenient breakdowns.
If you own a lead-acid wet cell battery, regularly check its electrolyte levels and top them off when necessary with distilled water. Clean the tray on an ongoing basis as debris accumulation can impede stability and performance.
Corrosion on battery terminals can restrict electrical flow, decreasing efficiency and shortening battery lifespan; regularly clean them using baking soda-water solutions or commercial protectants to extend their lives.
When not driving, unplug electronics such as radios and charging devices to reduce drain on your battery. While parked, use a car cover or park in shade for added cooling to protect its cells. Furthermore, consider getting your battery tested annually to monitor any deterioration that might reduce its lifespan.
Driving Habits
Your car battery produces electricity by means of chemical reactions within individual lead cells that release electrons to help start your engine and power electrical systems when your car is off, such as headlights and heaters.
But many factors can negatively impact the lifespan of your battery, shortening it more rapidly than you expect. Extreme temperatures can quickly drain the battery while prolonged inactivity or short trips over time can also erode it significantly.
Failing to perform maintenance may cause corrosion to form on terminal connections and reduce efficiency while left-on headlights or chargers that draw power directly from it can further deplete its energy reserves.
However, we can help you remain on top of its health and longevity:
- Listen out for any clicking or buzzing sounds when turning on the ignition
- Remove cables in their proper order (negative first)
- Clean and dry terminals to eliminate corrosion and help protect against potential damage.
- Test and replace batteries as necessary so you’re safe when driving.
Weather
Car batteries must withstand extremes in heat and cold in order to perform their primary task: starting your engine. Depending on where you live, an AGM battery may be best suited to withstand frequent starts-and-stops in hilly or mountainous terrain.
Inside a battery are six individual cells filled with lead and lead dioxide plates surrounded by sulfuric acid solution. When you turn on your ignition, this sends a small electrical current through to a starter relay (or solenoid), triggering it to close its contacts and produce enough voltage to start your engine and power accessories such as radio or wipers when not running.
Conclusion
On average, car batteries usually last three to five years before needing replacing, although many factors can shorten its life such as extreme temperatures, infrequent driving, poor maintenance and parasitic draws on the electrical system.
Therefore, it is recommended that an annual battery test be scheduled around the three year mark and to look out for warning signs such as visible corrosion on terminals or pungent sulfuric smell.
