Things to Consider When Buying a Jeep Wrangler Battery


Jeep Battery Guide


The jeep wrangler needs high cranking power as well as deep cycling provision on the battery to support the accessories such as your winch and off-road lights. The price of the battery will directly depend on the AH rating and the cranking power both of which are important.

However, the best jeep wrangler battery price should reflect the best service the battery can deliver and these are the factors to consider before paying for your jeep wrangler battery replacement.

  • 1. Shelf life

You should note that batteries have a self-discharge when idle and the longer the batter stays on the shelf, the shorter its lifespan becomes. Any battery that has been on the shelf for over 6 months will definitely have a smaller price tag value with a short warranty as well which may not be the best option for the high-performance demand of the jeep wrangler.

If you get a dead battery, don’t go for a jump start, contact the supplier for a replacement to stay on the safe side of your warranty.

  • 2. Compatibility

Jeep has over 3 decades of models with group 34 applicable to the 07-11 wrangler. The terminals have since changed accommodating Group 91 and you may have to pay for an adjustment if you make the wrong choice. You have to get the right size of the battery casing under your hood for a perfect fitting battery that eliminates the cost of adjustments.

If you are upgrading to a dual battery system for the first time, you may have to get the adjustments to fit the dual battery case. A perfect-fitting battery is less prone to shortages and destruction due to vibration. You also need to get the right position and size for the terminals.

  • 3. The Amperage Hour rating

The AH rating determines the time a battery will continue delivering reliable current when the engine is off. A high-performance battery for a jeep should have at least a 60AH rating to power the engine and offer you enough power for the appliances and lights when the engine is off. This guide contains the batteries with a reliable AH rating value that will last at least twice longer than s conventional starting battery.

  • 4. Recharge time and voltage

The best battery should have a short recharge time although the shorter the recharge time the quicker the drain speed meaning most batteries will need secondary recharge provisions. However powerful the battery is, the recharge is a direct determinant of its ultimate lifespan.

You cannot avoid short rides and they have an impact of draining the battery without allowing enough time for a full recharge making a battery charger or a reliable alternator a basic requirement.

You will need a regulated battery charger to smart recharge the battery and avoid overcharging which has the same impact. 13.8V to15v chargers or a regular 15v alternator will work for the batteries in this guide.

  • 5. Cranking Amperage capacity and battery reserve current time

The CCA rating determines the amperage the battery will deliver at zero degrees Celsius which is an important consideration for the winter. Most extreme cold temperatures like Canada and Montana winters will need up to 800CCA but any 750CCA and above CCA will start your car in common winters.

Long reserve capacity also offers more convenience for a longer and better accessory powering. However, these qualities should depend on the number of accessories you have in the car. If you use your car for a simple start and stop travel without many electric appliances, a regular Odyssey, Northstar or interstate battery will serve you for long.

Dual batteries with a combination of SLI and Deep cycling will offer the perfect service for most jeep wrangler engines and accessory functions.

  • 6. Warranty

The warranty is the direct pointer of the manufacturer’s actual estimation of the battery’s lifespan. Shorter warranties are given to batteries with a long shelf life most of which have self-discharged up to 70% which may be cheap but dangerous.

To get value for your money, the best jeep wrangler battery replacement should have a warranty of at least 3 years for starting and dual-purpose batteries and 4 years for a deep cycling battery.

The batteries in this review are from the best manufacturers offering the best jeep wrangler battery options for high performance with a minimum of 36 months warranty. This will offer the required value for your money.

  • 7. Battery Maintenance and safety

Make sure your battery is sealed and maintenance-free to avoid the inconvenience of checking water levels and other specifications all the time. This guide has all the lead-acid maintenance-proof battery brands you can choose from.

Heat results from reaction during the recharge and discharge cycles in your battery, you should ensure the battery has a heavy internal and external casing that can contain the heat. Too much heat affects the voltage stability reducing the AH rating during the performance. Low heat tolerance also means more electrolyte evaporation that leads to more sulfation.


Types of Batteries


Types of Batteries


The jeep wrangler runs well on regular lead-acid batteries and there are three main types.

  • A starting battery:

This is basically designed to offer maximum discharge to turn on the engine. They have small lead plates that react faster with the electrolyte to produce a strong discharge up to 30% of their capacity. They will die in less than 50 deep cycles as the plates wear out faster. Odyssey and Optima have boosted starter batteries in this guide that survive more deep cycles.

  • A deep cycling battery:

This battery will have a high CCA rating signifying the ability to discharge over 80% of its capacity and recharge without wearing out the plates. They have large lead plates but they do not start up as fast and as powerful as starting batteries.

They, however, have the ability to provide a stable current for a long making them ideal for the electronic accessories on your jeep wrangler.

  • A dual battery:

Dual-purpose batteries are simply improved starting or deep cycling batteries that can power more accessories while still providing a strong cranking power. A dual battery system will have a battery for each of the two roles reducing the weight on one battery as the alternator discharges the right battery for the starting before switching to the deep cycling while recharging the starting battery.


How to Replace A Jeep Wrangler Battery


Jeep Wrangler battery replacement is a very easy 20-minute or less task if you have the right battery with matching terminals, a regular wrench mostly 10mm, check with your manufacturer for details, and a memory saver.

You also need gloves to keep the whole process clean and safe. The manufacturer will give you the step-by-step guide but these are all the steps you will have to perform when replacing a jeep wrangler battery.

  • 1. Install your memory-saving device on the terminals to keep the accessories safe and avoid resetting anything in the car memory.
  • 2. Loosen the cables on the terminals starting with the negative terminal.
  • 3. Loosen the fasteners on the battery hold-down panel and remove the old battery.
  • 4. Insert the new battery into the tray. If you got the right size, the new battery should fit perfectly with matching terminals. The Jeep JK dual battery tray terminals are connected directly to the alternator.
  • 5. Replace the battery hold-down panel and fasten it then replace the positive cable followed by the negative cable fastening each after replacement.
  • 6. Remove the memory saver then close the hood.


Frequently Asked Questions


FAQs Jeep Wrangler Battery


a) Which is the best battery for a jeep wrangler?

  • This question will get a new answer every time you ask anyone. You will be told of Odyssey, Diehard, Northstar, and Optima yellow top, Optima blue top, and Optima red top all of which are good for one role or another.
  • Cranking and deep cycling are indirectly related, Deep cycling batteries are more expensive but they offer better performance service but are not as powerful in starting as SLI batteries. This guide has all you need for whatever your jeep wrangler does the most.

b) How long will my jeep wrangler battery last?

  • The number of deep cycles a battery can perform before the plates wear out is the biggest determiner of the battery’s lifespan. All new batteries should last at least 3 years. However, if you choose a low-quality battery or an unreliable brand, the low-quality of lead or electrolyte may reduce the lifespan to less than a year. You need to insist on at least 36 months of warranty as it signifies high-performance confidence and also keeps you safe from premature battery failure.

c) What is the significance of the AH and CCA rating on battery?

  • The CCA rating signifies the amperage your battery will produce at zero degrees for 30 seconds before a voltage drop. Deep cycling batteries are better suited for powerful cranking in the coldest weather with 800CCA ratings being best suited for most wrangler engines in the cold weather.
  • The AH rating, on the other hand, shows you How many hours the battery can produce 5A before dropping below 10V. The rating is based on 100-hour testing. Most batteries will either deliver 5A or 10 A continuously for 20 hours. It is important in determining how long your battery can power more loads when the engine is off without compromising the ability of the battery to start your car which needs 10.5V.

d) Is a dual battery necessary for a jeep wrangler?

  • Jeep Wranglers are accumulating more wiring with an increased electric load which weighs too much on any single battery. However strong your deep cycle battery is, having a dual battery will elongate its service while still getting you anywhere you need to go. The setup is quite expensive but it offers the best powering service for a better road experience.
