What Is Car Battery Replacement?
The battery in modern cars is used to crank over the engine as well as provide power for all of the various computers and electrical components. Needless to say, a dead or dying battery can result in a number of problems for your vehicle including no-start conditions that leave you stranded or having to jump start your car.
Even if you own an advanced hybrid-electric vehicle, these cars still use a conventional battery, which you can replace yourself. Replacement car batteries can be found at any auto parts store and even large retail stores such as Walmart.
The most expensive part of this repair is the cost of the replacement battery, and the job itself shouldn’t take more than an hour even for first-time DIYers. Car batteries are usually found under the hood in the engine compartment, but some cars (usually luxury and performance vehicles) have the battery mounted in the trunk.
When replacing a battery yourself, be careful of battery acid that may be leaking and be aware that batteries can be heavy and awkward to lift.
What Happens If You Don’t Replace Your Battery?
A dead battery could also leave you stranded or in need of a tow truck. Furthermore, not addressing an old car battery could potentially lead to battery acid leaks, which could result in damaged battery cables/terminals or other wiring damage near the battery.
Here’s how to replace your car battery and avoid any issues.
How Often Do Car Batteries Need to be Replaced?
Depending on the manufacturer of the battery in your car, most are designed to last between three and five years. Car batteries are sold by cold cranking amps and replacement warranties in months; the longer the warranty, the more expensive the battery.
