6 Best Batteries for Jeep Wrangler + Buying Guide

A Jeep Wrangler is a powerful 4WD that can easily tackle a wide range of off-road conditions. Because of this, it demands a powerful battery to fire up its engine when the key is turned. 

The right battery should have more than enough cranking amperes to power all the other accessories when starting the engine. Therefore, if your vehicle’s battery can’t turn over its engine when you start it, you will need a new battery.

There are many factors you have to think about when picking the best battery for your Jeep Wrangler, including reserve capacity and CCA. It should also be able to withstand harsh vibrations and jolts associated with off-roading. 

Picking the best one for your Jeep can’t be easy. So, we rounded up six of the best Jeep Wrangler batteries to help you choose one for your vehicle.

Our Top Picks for the Best Jeep Wrangler Batteries

1. Best Overall: Odyssey 34-PC1500T Automotive and LTV Battery

Currently, vehicles have more accessories than you would have imagined compared to three decades ago. So, to keep up with the electronics, battery manufacturers have started producing powerful units. If you’re looking for the best option for your Jeep Wrangler, then the Odyssey 34-PC1500T is one worth trying. This is our overall pick for the best battery for the Jeep Wrangler.

This dual-purpose battery can serve as a starting and deep cycling battery. It can also power your vehicle in winter when the temperature is really low. This unit comes with pure lead plates to make it possible for it to withstand deep cycles and crank the engine. If using two batteries to power your Jeep isn’t an option, then you should purchase Odyssey 34-PC1500T.

The lead plate increases the battery’s performance, changing rate while reducing the discharging rate. Therefore, this unit doesn’t lose energy like a high-internal resistance battery when discharging or charging. Plus, it only takes about 4 hours to charge it from 0% to 100%, thanks to the lead plates.

This unit delivers the massive starting power and deep cycling capability that your Jeep Wrangler needs. This unit has a CCA of 850 amperes, rated at 68Ah. This means that it can supply 68 amperes consecutively for 60 minutes. This unit is robust enough to power your Jeep even in bad weather conditions.

Like most batteries, the Odyssey 34-PC1500T comes with an AGM design. Therefore, it’s 100% leak-proof, and you will not need to add water. You will not even have to clean the terminals now and then.

Another feature that makes this battery stand out is the fact that its reserve capacity is about 185 minutes. This unit has the biggest reserve capacity of all the batteries in the market. 

It may be a bit expensive, but it’s worth the price as it is one of the most powerful options available.

Factors to Consider When Looking for the Best Battery for Jeep Wrangler

Regardless of whether you use your vehicle regularly or not, you need a battery that fits your Jeep perfectly. Besides the battery’s power and reserve capacity, it should be able to comfortably run your Wrangler’s engine and power its accessories. 

To avoid any inconvenience or to have to replace it regularly, you need a pragmatic and durable option. So, here are a few things to consider when buying a battery for your Jeep Wrangler.

Weight

Although weight will not affect performance, it is a very crucial factor to consider. Lightweight batteries are easier to remove and install. Remember, you will have to remove and store it come winter, so you should get a lighter option.

Safety

The chemical reactions that occur when the battery is being used are quite dangerous and can produce harmful emissions. For the safety of your Jeep, you should avoid a battery with an inferior construction. Look for a battery that is spill-proof and leakage-proof.

Power

Another crucial factor you have to consider is the CCA of the battery. Plus, with Jeep Wranglers being huge vehicles, you need a powerful battery that can crank its engine even when it’s cold. But most importantly, the new battery’s power rating should match those for your vehicle.

Size

Generally, Jeeps are built differently, so their battery compartments may vary in size. You need to understand the dimensions of your Jeep’s battery compartment before ordering a new battery. 

Make sure you measure the battery compartment and get an option that fits your Jeep perfectly. Do take note that the size of the battery doesn’t have anything to do with its weight.

Maintenance

The only maintenance you have to worry about is adding water to the electrolytes when it comes to car batteries. So, the best thing to do is to go for a maintenance-free option because you may never have time to maintain the battery. You won’t need to add water or change the plates with maintenance-free batteries. All you have to do is install the battery and connect the terminals, and you’re good to go!

Compared to other conventional batteries, maintenance-free batteries are quite costly. But it is worth the trouble associated with maintenance.

CCA

CCA, or cold crank amperes, refers to the amperage your battery can deliver when the temperature is at 0 degrees Celsius. The CCA is quite crucial when starting the engine in winter. 

A huge percentage of the cold temperatures in North America require a CCA of about 800 amperes. Anything over 750 amperes can start the Jeep Wrangler in a common winter.

Recharge Time

The recharge time is also crucial for picking the right battery. Remember that car batteries also run out of charge, so you need an option with a shorter recharging time. Make sure you avoid getting batteries that take longer to recharge.

Vibration Resistance

Jeeps are off-roaders, so all their parts, including the battery, are exposed to harsh road conditions. Therefore, you need a vibration-resistant battery that is both spill-proof and can withstand the bumping and vibrations associated with off-roading.

Reserve Capacity

Reserve capacity refers to the amount of time the battery can power the car’s accessories when the engine is off. A battery with a longer reserve capacity can be a lifesaver for people who love the outdoors. And that is because it will let you reach your destination before it runs out.

FAQs

Which is the best battery for my Jeep Wrangler?

The answer to this question will depend on the person you’re asking. You will be told Northstar, Optima, or Odyssey batteries are the best options for a Jeep Wrangler in most cases. These batteries are exceptional, but you have to consider your Jeep’s needs. If it has many electronics, you should go for a dual-purpose battery.

How long will the battery last?

The biggest determinant of the battery’s lifespan is the number of deep cycles it can perform. But all new batteries should serve you for more than three years. A low-quality battery has a short lifespan than most high-end options. So make sure you get a battery with a longer warranty, as it shows the manufacturer’s confidence in their product.

Are dual-purpose batteries ideal for Wranglers?

Generally, vehicles are accumulating more wiring, thanks to the many electronics they have. This will increase the electric load that can overwhelm a single battery. So instead of a single battery, you can go for a dual-purpose unit that can service your Jeep for an extended period.

Dual-purpose batteries are quite costly. But they are worth the price, especially considering the number of accessories they will power. A powerful dual-purpose battery can also start your Jeep when it’s cold or too hot.

Conclusion

Owning a powerful battery can be a lifesaver. A robust battery will make life fun and with very few hassles. You will never have to jumpstart your Jeep Wrangler every time before leaving your garage. Therefore, it’s important that you get the right option for your reliable vehicle.

You need a dual-purpose battery with a high CCA, lightweight, and a very long reserve capacity. It should also be vibration-resistant and durable. We believe that Odyssey 34-PC1500T Automotive and LTV Battery is the best option from our list. This battery has a very short recharging time, high CCA, and can power all the accessories in your Jeep.
