Should I replace the car battery with a larger capacity than the original?
After a period of use, the car battery will be damaged, run out of power and need to be replaced. However, when choosing a replacement battery for a car, many people wonder whether they should replace it with a new battery with a larger capacity than the original battery installed in the car (!?)
Similar to some parts and accessories such as engine oil, gearbox oil or spark plugs, the battery in a car will be damaged after a period of use and need to be replaced. According to auto technicians, depending on the habits and environment of the car, on average a battery installed in a new car usually has a lifespan of 1.5 - 2 years, some cars even have a longer battery life. However, there are also many cases where the battery in a new car has been damaged after less than 1 year of use.
With the development of the automotive support industry, car users in Vietnam now have many choices when they want to replace their car batteries. With dozens of battery brands entering the Vietnamese market in recent years, with a budget of 1.2 - 3 million VND, car users have dozens of different choices depending on each brand and different battery segments.
However, besides price or brand, one thing that many car users wonder about is whether or not they should replace the battery with a new one with a larger capacity than the original battery in the car when it is damaged (!?)
Capacity is measured in Ampere (Ah), this parameter helps car users know how much electricity the battery can store. Most popular car models in Vietnam today are usually equipped with batteries with a capacity of 40Ah - 60Ah.
In fact, during the process of using cars, many car owners have chosen to replace them with new batteries with a larger capacity than the original battery. For example, in the case of Mr. Nguyen Huy Cuong, residing in Thu Duc City, Ho Chi Minh City, he is using a 2021 Hyundai Accent. According to Mr. Cuong, this car was bought new and was equipped by the manufacturer with an original 45Ah battery. After more than 2 years of using the car, when the battery was damaged and needed to be replaced, after consulting with a number of auto repair technicians, Mr. Cuong chose a new battery with a capacity of up to 60Ah to replace his Accent. Up to now, the car is still operating stably.
In fact, after a period of use, the car battery is damaged, you can still choose a new battery with a larger capacity than the original battery to replace it. However, according to the recommendations of technicians specializing in car repair and maintenance, you should choose a new battery with a capacity larger than the original battery by about 10% - 15%.
In addition, if you choose a new battery with a larger capacity than the old battery, you should pay attention to whether the battery size and the location of the terminals are suitable for the battery installation space on the vehicle or not. Because there have been cases where car owners choose a new battery with a larger capacity than the original battery but cannot install it because the battery size is larger and there are no pins to fix the battery. In addition, some types of batteries also have the battery terminal positions (negative terminal, positive terminal) opposite to the original battery on the vehicle, so it is also difficult to install.
In addition, before choosing a new battery with a larger capacity to install in the car, you should consult with technicians specializing in car repair and maintenance. Because depending on each car model, installing a new battery with a larger capacity than the battery capacity equipped by the manufacturer will more or less affect the generator as well as the car's charger.
