You can reduce the cost of replacing a car battery by doing this job yourself. The cost of a battery, though, is completely dependent on the type of vehicle you own and the type of battery you choose to buy. Performance batteries or those with a longer warranty will cost more, but the best bet for most DIYers is just to just an OEM-style replacement.
Keep in mind: Just about all batteries are different, so make sure you have all of the proper information on hand when ordering a new one to avoid wasting your time or potentially damaging your vehicle or the battery. When in doubt, always refer to your owner’s manual.
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?
Generally speaking, a dead battery won’t cause any damage to your vehicle, but it could result in the battery warning light coming on or a slew of possible check engine light codes. In some newer vehicles with a multitude of computers, a dead or low battery could the engine not to start meaning that you could be 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. For more information on how and when to replace your car battery, consult your owner’s manual for specified maintenance schedules or use the FIXD app for automated maintenance tracking.
Sometimes, an electrical draw can cause the battery to drain prematurely, and in this case, installing a brand-new battery won’t necessarily fix the problem. Here’s how to prevent your battery from draining fast.
