Best Battery for Jeep Wrangler Buying Guide

Jeep wranglers require great cranking power, along with deep cycling provisions on the battery for supporting the accessories like your off-road light and winch.

The cranking power and the AH rating are both important factors for the battery, and its price also depends directly on these two aspects.

But the best battery price should be a reflection of the best service offered by the battery. And, these are also the factors to take into account when paying to get the jeep wrangler battery replaced.

  • Shelf Life Of The Batteries:

It is important to keep in mind that any battery has a self-discharge when they remain idle. The longer the battery remains in the storage, the shorter the lifespan of the battery gets.

Batteries that have remained in the storage for more than six months will certainly come with a small price tag value, along with a brief warranty. Such a product might not be the right choice for the level of performance demanded from a jeep wrangler.

Do not try to jump start if you have landed a dead battery. Get in touch with the supplier to demand a replacement, while you are still on the right side of the warranty.

  • Compatibility With The Model You Own:

Jeep comes with more than three decades of models, and the group 34 is applicable to 07-11 jeep wrangler. Now, the terminals are no longer the same ever since Group 91 has been accommodated, and you might need to pay for adjustments in case any wrong choices are made.

It is crucial to have the proper size of the battery casing for your jeep for the rightfully fitting battery which can eliminate the hassle and costs of adjustments.

In case you’re planning to upgrade to dual battery systems for the first time, you might need to make adjustments for fitting any dual battery case.

A perfectly fitted battery is more protected from any kind of destruction and shortages because of vibration. Also, you need the right size and position for the battery terminals.

  • The Ratings For Amperage Hour:

The ratings for amperage hour regulates the time for which the batteries will keep on delivering steady current while the engine stays off.

The high-performance batteries for the jeep need to have no less than 60 AH rating for powering the engine and provide you sufficient power for the lights and appliances while the engine stays off.

You will find jeep wrangler batteries with good AH rating values that will last more than the traditional starting batteries.

  • Voltage And Recharge Timings: 

The right battery needs to feature a shorter recharge time, though having a shorter recharge time will hasten the drainage speed.

So, most of the batteries will require provisions for secondary recharge. But recharge is the major determinant of the ultimate lifespan and the power of the battery.

Short rides on a jeep cannot be completely avoided. They might have a major impact on draining the jeep’s battery, without leaving enough time for a complete recharge. Thus, a reliable battery charger or an alternator might be a basic need.

A regulated charger is a must for smart recharge of the battery and escape overcharging that might have a similar impact. Battery chargers of 13.8 V to 15 V or even regular 15 V alternators might work well for most batteries of good quality.

  • Battery Reserve Time And Cranking The Amperage:

The CCA rating controls the amperage to be delivered by a battery at zero degree Celsius, and this is a significant consideration for the colder seasons.

In the areas of extreme cold, at least 800 CCA is a must. However, about 750 CCA and more will be able to start the car in all kinds of weather.

Longer reserve capacity also leads to more convenience for better and longer accessory firing. But the number of accessories present in the car would also dictate all these qualities.

In case the jeep is used for simple short distance travel, minus multiple electrical appliances, a regular battery of good quality will last for a long time.

The dual batteries that have the combination of deep cycling and a SLI will provide enhanced service for a majority of accessory functions and engine of the jeep wrangler.

  • The Warranty Offered By The Brand:

You will get an inkling of the actual estimation of the manufacturer regarding the lifespan of the battery by looking at the warranty offered by the brand.

Generally, the batteries with a longer shelf life have shorter warranties because they have self-discharged about seventy percent which might be cost-effective but dangerous.

As such, to ensure the best value for money, the jeep wrangler battery should come with a warranty of a minimum of three years for dual-purpose and starting batteries and at least four years for deep cycling batteries.

You will find batteries from the finest manufacturers in the reviews given above. All the batteries discussed above offer high performance and come with enough quality and warranty to ensure that you get the right value for money.

  • The Safety And Maintenance Factors Of The Battery:

Ensure that the batter is maintenance free and sealed for avoiding the inconvenience of examining water levels and additional specifications all the time. You will find maintenance proof batteries in the guide stated above.

The reactions caused during the discharge and recharge cycles in the battery leads to considerable heat generation. You need to make sure that the battery comes with heavy external and internal casings that have the ability to hold the heat.

Voltage stability gets affected by excessive heat generation, thereby bringing down the ampere hour rating at the time of the performance. Increased electrolyte evaporation is also the result of low heat tolerance, which further leads to greater sulfurization.

How to Replace Your Jeep Wrangler Battery
