How Long Do Car Batteries Last?

When you buy a new, high-quality battery, you can expect it to last three years on average. Low-quality batteries typically last less than this, with some lasting as little as a year, which is why buying from reputable brands is advised.

Types of Car Batteries

There are a few different car battery types to know about.

  • Conventional lead-acid. The most common type of vehicle battery is a conventional lead-acid battery. They convert chemical energy into electrical energy using sponge lead and lead peroxide. The inexpensive cost and ability to create a powerful pulse make lead-acid batteries popular.
  • VRLA. A rechargeable battery is a valve-regulated lead acid battery. They may be placed in any direction and require little maintenance.
  • Lithium-ion. Lithium-ion batteries are the rechargeable batteries you’re familiar with in electronics, such as mobile phones, laptops, etc. They have a high energy density and a small memory effect.

What Should I Look For When Buying a New Jeep Battery?

Here are a few features to pay attention to when purchasing a new Jeep Battery.

Shelf Life

When batteries are not in use, they self-discharge, and the longer they are not used, the shorter their lifespan gets. We recommend avoiding any battery that has been sitting for more than six months because it is unlikely to meet the Jeep’s high-performance requirements.

Cold Start

Do you live in a cold climate with severe weather? If that’s the case, you’ll want to make sure your battery always starts, even when it’s cold outside. You’ll want to look for anything with a high cold cranking amperage (CCA) figure in this situation.

Time to Recharge

The best batteries have a quick recharge time, but the trade-off is that they drain quickly as well. If you buy a battery with a short recharge period, it’s a good idea to have a backup on hand.

Reserve Capacity

Reserve capacity is a good feature since it provides power for a short period of time even if your alternator is not charging the battery. It may also assist you in getting to your destination before running out of battery power. It should be possible to use electrical components while the engine is turned off.

Vibration Resistance

Vibration resistance is an important characteristic for Jeeps, as it allows them to endure all of the harsh handling that comes with this vehicle type.

People Also Ask

Let’s wrap things up with a few common questions vehicle owners have about car batteries.

How Does a Battery Work?

Car batteries work by producing lead-acid chemical reactions that get energy flowing. Instead of delivering lots of power all the time, they offer a jolt of power for your electronics. Once everything is going, the alternator keeps power stable.

How to Dispose of Batteries

Batteries should be recycled in special facilities that are equipped for this task. Many people take their old battery to an auto shop and turn it in when purchasing a new one. You can also take it to a scrap metal facility or your local recycling center.

What is an AGM Battery?

An AGM battery, or absorbent glass mat, is a sealed replacement for lead-acid batteries that’s been in use for around forty years. They have special fiberglass mats that absorb sulphuric acid in the battery, which makes them spill-proof.

How Much is a Car Battery?

The cost of a car battery can range anywhere from $60 to $120. If you choose a premium battery, the price can go up even more, with these models costing up to $250.

Why is My Battery Draining so Fast?

If you’ve had your car battery for several years, it’s probably time for a new one. If it’s still relatively new, some other culprits may be to blame. Namely, there is likely some drain-depleting battery power or a problem in your vehicle’s electrical system.

How Many Amps is a Car Battery?

Ampere ratings tell you a battery’s storage capacity, and most batteries have a capacity anywhere from 550 and 1000 amperes.
