How to tell if your battery needs replacement whenever it gives bad battery symptoms

In today’s world, batteries play a key role in energy storage and the production of electricity. Batteries are the power source for most devices, including phones, laptops, cars, solar panels, power bikes, television, and many other gadgets. Why does someone else’s battery last so long, while my own battery quickly fails.

However, when batteries get old, their potential to power devices reduces over time. When a battery is getting weak or dying, it gives signals (bad battery symptoms). However, many people only use their device daily, they are not familiar with the bad battery symptoms batteries give.

Do you feel like your battery symptoms are getting worse? Through this article, you will acquire useful and helpful information about a faulty battery, and the symptoms they have when they can no longer power your device.

Take your time to explore this article, you will learn more about how a battery behaves when they are bad. You will also know the things that cause a battery to go bad, how to keep your battery from dying and tell if your battery needs a replacement.

What are the bad battery symptoms

There are several bad battery symptoms or signs a battery gives when it is weak or damaged. Some of the symptoms include corroded terminals, rotten odd smells, and failure to charge. Also, if after withdrawal of the charger, your battery instantly drops its charge, that is a symptom that your battery is no longer fit to power your device. There is swelling is also a bad condition. The ones that signal an instant replacement of the battery include failure to charge and low energy storing capacity. In addition, overheating is also among the bad battery symptoms a battery gives when it’s weak or damaged.

What happens when your battery is bad

There are a lot of negative effects of a bad battery on the device it is used to power. In situations where you leave a bad battery in a device, it will enhance the bulging and swelling up of the device. Also, when charging a bad battery, the effect of the battery on the device will instigate an unfavorable rise in the temperature of the device which usually leads to overheating.

Batteries such as lithium-ion batteries are designed to charge faster, when you experience a slow charging rate of these batteries unlike when they are new, that is a sign of weakness that calls for battery replacement.

How can you tell if the battery needs replacing

When a battery need to be replaced, it finds it difficult to start (switch on) the device to which it is applied.

Also, when a device goes off immediately after charging, it shows the battery is no longer capable of storing the energy required to power the device, hence it should be replaced. Sometimes, batteries would not give bad battery symptoms, they just stop working, in cases like this, it is advisable to get a new battery.

What causes a battery to go bad

Several factors could instigate the weakness or destruction of a battery. A battery might get damaged as a result of poor maintenance, or as a result of aging. Some batteries have a long cycle life, such as lithium-ion batteries, which can reach 4,000 cycles. While some batteries have a shorter cycle life, such as lead-acid batteries, whose capacity decays to 80% after 500 cycles

Scientifically, batteries generate electricity according to their chemical reactions. After many
chemical reactions, the electrolyte would become weak, leading to obstruction in the flow of electrons from one electrode to the other, hence damaging the battery.

Also, when there is poor maintenance of a battery, it may lead to its destruction. For instance, if a battery is left uncharged for a long period, it would lead to a reduction in the battery’s capacity to store up energy, hence making the battery ineffective.

Is a dead battery a bad battery

A dead battery is not necessarily a bad battery, because it can still be recharged. When a battery is bad, it is in a situation that even when charged, it will instantly lose all its charges. If a battery is giving bad battery symptoms, it is believed to be in a stage where replacement is unavoidable.

How do I keep my battery from dying

A battery can be prevented from unwanted damages through good management and maintenance. Proper charging will help your battery go a long way. If a battery is kept unused for a long time, it may cause damage to the electrolyte that serves as a conductor inside the battery, leading to the damage of the energy storing capacity of the battery itself.

When you keep your battery safe from water, and other physical abuse that can cause corrosion, your battery would not develop unwanted faults. Also, if you want to keep your battery from dying, make sure you charge it at a favorable temperature.

Can a battery be fully charged and still be bad

It is possible to get a bad battery fully charged or maybe the reason is that the battery is unbalanced, and a battery cell is broken. When your battery drops all its charge immediately after its fully charged, it is giving bad battery symptoms, hence it requires an instant replacement.
Also, when your battery charges for a longer period before getting fully charged, it shows the battery is weak or bad.

Will my battery come back to life

In situations where the battery has lost its capacity to store energy, it is advisable to get the battery replaced. Also for batteries that get damaged and result in a swollen state, it is best to get a new battery, because the battery container of  swollen battery has been badly damaged.

Final thoughts

A battery just like your devices (phones, laptops, solar panels), requires proper management. When a battery gives bad battery symptoms, do the needful by charging it properly. If after charging the symptoms persist, quickly get the battery replaced.
