Why is My Car Battery Losing its Charge? Reasons & Fix

This post was most recently updated on May 16th, 2023

Batteries are a necessary component of daily life. Our laptops, cell phones, and other electronics are all powered by them. Nevertheless, batteries frequently lose their charge over time, which is a problem. This could be more pleasant, especially if your device is essential to you. This article will examine the causes of battery discharge and offer some advice for resolving the problem.

Reasons why batteries lose their charge

1. Ageing 

Batteries lose some of their ability to hold a charge as they get older. As a result, they won’t be able to retain a full charge like they could when they were brand new. Unfortunately, it is impossible to stop this natural process. But, depending on factors like usage, temperature, and humidity, certain batteries may age more quickly than others.

2. Overcharging

Overcharging can harm the battery and hasten the rate at which it loses charge. Overcharging a battery results in heat production, which can hasten the battery’s deterioration. Explosions and other safety risks could result from this.

3. Undercharging

Similar to overcharging, undercharging can hasten the battery’s loss of charge. In addition, a battery may experience a memory effect if it is not charged ultimately. This means that even after a lengthy charge, the battery won’t be able to maintain a full charge.

4. High temperatures

Batteries can lose their charge more quickly in hot weather. This is because a battery’s internal chemical reactions may intensify at high temperatures, hastening the battery’s deterioration.

How to fix batteries that are losing their charge?

Now that you are aware of the reasons why batteries lose their charge, and you must know how to extend their life. You can maintain your battery’s performance for years to come by using a few simple tips and practices.

1. Refrain from deep overcharging

This process occurs when a battery is used to the point where it causes damage. Degradation of capacity and the potential for short circuits result from it. Anything below 2.5 volts per cell is typically considered to be the line in the sand since it will eventually cause the battery to activate a safety circuit and halt further operation. So try to limit your discharges to partial ones instead. However, experts advise that once every 30 cycles or so, a discharge to very close to that threshold will assist in resetting your device’s digital memory.

2. Avoid Physical Damage to Your Batteries and Its Components

This ought to be self-evident. Any number of things can happen when a battery sustains physical damage. There is a risk of fire when the film separating the electrodes from the electrolyte is punctured. The container may begin to leak toxic contents. Physical harm is quite risky. Despite their durability, try to avoid striking, scratching, or otherwise negatively harming your battery. Don’t charge your battery if it has physical damage. 

3. Prevent High or Low Temperatures

The ideal temperature for batteries is 20 degrees Celsius, or 68 degrees Fahrenheit. However, batteries dramatically reduce their efficiency between 40 and 50 per cent at extremely high and low temperatures, which adds to general deterioration. This explains why starting car batteries in the dead of winter can occasionally be challenging. Nevertheless, charging a battery is a completely different game. Consider the range between 5 and 45 degrees Celsius, or 41 and 113 degrees Fahrenheit, as the ideal ambient temperature for charging lithium-ion batteries. Lithium-ion batteries become far more prone to failure when charged in subfreezing conditions because of a phenomenon known as “plating” of the lithium component.

Bidding Words

In conclusion, batteries are a vital part of our daily life; thus, properly caring for them is crucial. You must go for a periodical battery check to ensure whether it’s time to get a service , get it charged or need a battery replacement. There are solutions to the problem of batteries losing their charge for various causes. You can increase your battery’s lifespan and ensure your device functions appropriately by limiting usage, lowering screen brightness, closing unnecessary apps, changing the battery, and keeping the device cool.
