  3. 3. Lithium Ion Batteries:
    Electric Vehicles (EVs) use lithium-ion batteries since these batteries are designed to endure daily charging and discharging. These batteries are warranted for about 5 to 8 years but can easily last for 10 to 20 years.
  4. 4. NiMH Batteries:
    Hybrid Vehicles require Nickel-Metal Hydride batteries to operate properly. These batteries have a lifespan of about 8 years.

Factors that Affect Battery Lifespan

However, the chemical composition of these batteries is only one of the reasons that affect their life. There are several other external factors that influence the life of these batteries. These are:

  1. 1. Time:
    Batteries tend to suffer from wear and tear with the passing of time. This happens because of the frequent charging and discharging. Batteries that are pushed beyond five years can suddenly fail.
  2. 2. Temperature:
    Extreme weather conditions can also cause the batteries to deteriorate over time. Extremely hot weather can cause the battery fluid to evaporate and damage the internal cells. On the other hand, cold weather can decrease the performance of the battery.
  3. 3. Vibrations:
    Sudden or continuous vibrations can severely impact the life of a battery. Mount your battery securely and use rubber cushions to further minimize the impact.
  4. 4. The proper amount of charge:
    Proper charging of the battery through the alternator is vital. It is crucial to note that undercharging, overcharging, or letting the battery dry out completely can all lead to reduced lifespan.

A proper understanding of the different types of batteries and the external factors that affect their lifespan will equip you with an understanding of how to extend their lifespan and avoid unwanted breakdowns.

How to identify if a Battery is About to Die?

A well-maintained car battery will keep your car running smoothly for years at length. But sometimes the battery may silently struggle. Recognizing the signs of a failing battery will not only prevent you from being stranded on the road but also enable you to intervene in a timely manner and get the battery replaced. Here are some signs that you must look for in your car to notice if the battery needs a check:

  1. 1. Look for Electrical Issues:
    Notice if your headlights begin to dim while sitting idle but brighten upon revving the engine. This is a clear sign that the battery is about to die. If other electrical components show similar signs, the battery needs attention.
  2. 2. Multiple attempts to start the engine:
    If you have to twist the key multiple times to start the engine, this is another clear sign that the battery is nearing its end. You might be able to squeeze in a few more ignitions before battery replacement becomes inevitable.
  3. 3. Check the engine light:
    While a lit engine light doesn’t necessarily mean a failed battery, it is often a sign that there’s something wrong with the alternator. This is not a good sign since the alternator directly affects the battery.
  4. 4. Check for a foul smell:
    A damaged or leaking battery is likely to release an unpleasant foul smell. This is because of the presence of sulphuric acid.
  5. 5. Check for corrosion in the connectors:
    With age, the battery terminals usually develop corrosion. Corrosion causes ignition problems and terminal failures.
  6. 6.Deformation in battery:
    If your car battery is losing its shape, cracking, or bloating, it is a sign that your battery needs to be changed immediately.

Keeping track of all the above warning signs of a battery can help you address these issues early on and avoid inconvenient breakdowns. Regular checkups also help extend your battery’s life.

Regular Car Battery Maintenance: Steps for Longevity

A healthy and well-maintained car battery is the key to guaranteeing that your vehicle starts reliably, even in adverse situations. In order to extend the life of your battery and avert unexpected breakdowns, consider the following tips:

  1. 1. Timely battery replacement:
    Lead Acid batteries have a fixed lifespan: anywhere from 3-5 years. Yes, they can keep running for a longer time in certain cases but it is best recommended to get the battery replaced after four years. Adhering to this schedule will avoid the frustration that comes with a sudden breakdown.
  2. 2. Regularly Check for acid levels:
    When the battery is not completely charged, and its charge remains below 80% for an extended period, it can lead to acid stratification. This will prevent it from regaining full charge again. If your vehicle is only used for short trips or uses multiple power-hungry accessories, make sure to check the acid levels in your battery since acid stratification causes the electrolytes to concentrate at the bottom, leaving the upper part starved.
  3. 3. Maintain water levels:
    If you notice that the electrolyte levels are low, this means that the plates of the battery are exposed. Add distilled water to cover these plates. Use a funnel to fill the battery and avoid spillage. Use a battery charger to recharge the battery after adding water. This will ensure optimum battery performance.
  4. 4. Perform battery load tests:
    It is advisable to have comprehensive battery maintenance conducted each month. Ask a mechanic to perform a battery load test and verify that the battery is in a condition to charge efficiently even in freezing temperatures.
