Find out the typical life span of a car battery and get tips on spotting signs of battery problems and faults with the RAC guide.
The life cycle of an automotive traction battery is structured along two main paths: the primary life cycle, which lasts until the end of the battery’s first life in the vehicle, and the secondary life cycle that follows. In this white paper, the focus lies on the latter. The term “end-of-life battery” (EoL) is used in this context to

There is no simple answer, but based on decades of industry experience, we know that three key factors affect the life of a car battery: time, heat and vibration.
Batteries gradually deteriorate until they can no longer provide enough power to start an engine. This wear time could take three to five years and a vehicle's usage pattern is one factor contributing to the rate at which a battery will age. Batteries in cars driven mostly on short trips may not fully recharge and batteries in vehicles parked for e...
Heat facilitates the chemical reaction car batteries use to generate electricity, but it also increases the rate of battery degradation. In cooler northern climates, a battery may last five years or longer, but in hot southern locales, a car battery will typically last approximately three years. Batteries reside in a harsh under-the-hood environmen...
Vibration causes internal battery parts to break down. To minimize vibration effects, use special hold down hardware to secure the battery in place and prevent it from moving. Missing or loose hold down hardware can significantly shorten battery life.
While less common than the aforementioned factors, a malfunctioning charging system will also reduce battery life. Persistent under- or over-charging accelerates battery aging. Some newer cars with absorbent glass mat (AGM) batteriesrequire careful control of charging rates for maximum battery life, and the automaker may even alter the charging str...
You may have a battery problem if the starter motor cranks the engine slowly or the Battery/Charging warning lamp illuminates on the dashboard. In older models, dim incandescent headlights, particularly when the car is idling, indicates a weak battery. Not every failing battery reveals itself through obvious symptoms so take precautions to avoid a ...
You must consider the battery type, physical size, terminal configuration, and cold cranking amps (CCA) or amp-hour (Ah) rating to ensure you get a car battery that properly fits and functions for your make and model vehicle. Installing an incorrect battery can adversely affect the car's electrical system and cause major damage if the terminal loca...
Batteries are either conventional lead-acid or the more advanced AGM design previously mentioned. Most cars on the road today use conventional batteries and some models use AGM batteries. These batteries are highly spill resistant and better able to handle repeated discharging and recharging, as occurs in cars that have engine stop-start systems to...
The group number, for example Group 24, is an industry standard that defines the battery's physical size, its hold down configuration, and the type of terminals and their location. Selecting a battery with the same group number as the original equipment battery will ensure a secure fit, adequate clearance, and no cable/terminal issues. It will also...
The cold cranking amps rating, for example 650 CCA, is an industry standard measure of how much electrical power a battery can provide at zero degrees Fahrenheit. Never confuse this rating with "cranking amps" (CA), a rating based on an easier test that produces inflated numbers. Some import automakers state battery power requirements using an amp-...
Primarily, time, heat and vibration impact how long your battery will last. Recognizing the signs of a weak battery and understanding the factors affecting battery life can help you avoid unexpected breakdowns. Let's explore these warning signs and offer tips for choosing the right replacement.
Understanding the factors affecting car battery lifespan and following expert advice can significantly enhance your battery’s performance and longevity. Regular checks, proper maintenance, and mindful driving habits are essential for maximizing your car battery’s lifespan.
There are several factors that can affect a car battery lifespan including temperature extremes, taking regular short trips, long periods of inactivity, vibrations from rough journeys and the number of electronic devices like sat navs and smartphones that join you on your drives.

Jun 10, 2024 · One of the most important factors that affect a car battery’s life is the weather. A running engine under the hood is already producing high levels of heat. Throw in a scorching hot day and you may get a severe drain on your car battery, which can lead to an increased chance of a dead battery if you don’t take proper summer driving precautions.
