Cons Of Using An Overvolt Car Battery

Each technology that is present around humans is developed with the aim of making their lives easier. A lot of effort and resources go down in bringing an idea to life. However, everything that comes out such as a revolution is flawed with one problem or the other. The same goes for car batteries.

A car battery is one of the two sources utilized by a car to derive power and perform necessary actions. To accommodate the needs of each and every type of car, car batteries are offered in different compositions and capacities. However, this advantage sometimes proves hazardous for some customers due to the lack of proper knowledge. Car manufacturers often suggest a certain volt battery that is best suited for a specific car model through the medium of websites and manuals. However, such resources are barely referred by most customers upon the purchase of a car.

With that in mind, here are some cons of using an overvolt car battery:

Needs dedicated protection:

Lithium-ion batteries which are over the recommended voltage limit are quite famous for being unstable in certain cars. They intake and give out charges now and then; leading to a continuous charge-discharge. This phenomenon classifies current as an unstable charge that often breaks the barriers of safety limits. The absence of a device like a dedicated electronic circuitry can seriously harm car components by enabling it to flow over safety limits.

While modern cars come equipped with smart voltage controllers, the same couldn’t be said for old cars. The presence of smart circuitry allows people to make use of any car battery without having to have a piece of special knowledge. This protection circuitry not only blocks excessive voltage that could damage the cells but also assures that the battery power doesn’t go too down if a discharge happens.

Faster aging:

Car Battery Faster Ageing

Since high power overvolt batteries have to deal with a lot of power, they are at an ultimate disadvantage of faster aging. A typical Car battery has a lifespan of 3-5 years. This lifespan is typically decided by different factors like weather, driving habits, and the cycles undertaken by a car battery.

Overvolt car batteries end up discharging more than required power across different car components. This cycle of aging is also rapid if the battery is of lithium-ion nature. Hence, using a overvolt car battery is not advisable as one might have to visit a maintenance shop to repair or replace car battery over and over again. High voltage car batteries are also infamous for losing excessive charge on standby mode if they are not stored with a partial charge in a cool space.

Transmission upgrades:

Making use of a high volt car battery can also lead to excessive protection costs. This is especially with regards to upgrades that a car owner would need to do to the transmission of the car. These costs are large with respect to insulating the current moving conductors as well as getting better terminal components switchgear and transformers. Going for such costly installations for the sake of installing a high voltage car battery can also bring up unexpected upgrade costs.

Expensive:

The higher the voltage of the car battery, the higher its price. Price is indicative of multiple factors that go behind the construction of a battery. It is generally noticed that the price of a car battery is affected by the materials and power of the cells inside the battery. For instance, a battery made with nickel-cadmium cells is about 40-50% cheaper to produce as opposed to lithium-ion cells of the same size. Cost becomes a prime factor of concern for buyers and manufacturers where additional costs may arrive if unexpected costs show up.

Physical problems:

Overvolt car batteries may not necessarily fit within a certain assembly. Each car interior comes with a fixed area for specific components and their compartments. A battery compartment can only handle a car battery properly when it’s under its maximum limit. Trying to fit a heavy, big, and overvolt car battery forcefully may damage the holding assembly. Even if the bigger battery gets fixated inside the assembly, there are chances that it may explode under extreme conditions due to a lack of proper ventilation and space around it.

Installing new wires and controllers:

Wires that are responsible for transmitting current from the battery to components are limited by the amount of charge that they can pass at a time. Installing a higher voltage battery may also lead a car owner to install thick wires. Thicker wires are capable of handling excessive amperes pushed out by car battery and ensure that they don’t burn out and keep working to deliver the power without damaging the windings.

Apart from this, a car owner also needs to ensure that a proper controller is installed to accommodate a newer power distribution system. This system also includes the installation of components like capacitors and LVC that help regulate excessive charge properly across the car. This too adds up being unnecessary for the sake of having an overvolt battery.

Motor heating:

Overheating Car Battery

Car motors are known to overheat under excessive phase amps. Cars that are befitted with throttling systems are best known for controlling excessive amperes delivered to motors and prevent internals from heating beyond limits.

Component incompatibility:

This is one of the biggest reasons why one must not opt for an overvolt battery. For example, installing a 24v car battery in which 12v is the maximum limit can cause some components to stop functioning in extreme cases. Generally, components like connectivity and telephonic equipment are affected by this. To make an overvolt battery work with such components, one needs to assure that a proper voltage regulator or controller is installed to assure their working.

These are some of the most serious cons of installing an overvolt car battery. As it is a challenging process to make a car suitable for higher voltages, most car manuals suggest car owners install a car battery only after referring to the max limit as prescribed in the documentation. In this way, a car owner gets the benefit of a proper battery installation and no unexpected costs at the same time.
