Some models of the 2015 Jeep Cherokee have auxiliary batteries. These batteries support additional features. They are smaller than the main battery but equally important.

Auxiliary batteries can power systems like the start-stop feature. They help reduce the load on the main battery. This improves the overall efficiency of the vehicle.

Not all Jeep Cherokee models have auxiliary units. Check your vehicle’s manual to confirm. If your Jeep has an auxiliary battery, maintain it well. It ensures optimal performance of your vehicle.

Battery Type	Location	Function
Main Battery	Under the hood	Powers engine and primary systems
Auxiliary Battery	Varies by model	Supports additional features

Types Of Batteries Used

The 2015 Jeep Cherokee uses two main types of batteries. These are the Standard Lead-Acid and AGM Batteries. Each type has its own benefits and uses. Let’s explore them in detail.

Standard Lead-acid

Standard Lead-Acid batteries are the most common in vehicles. They are reliable and affordable. These batteries use lead plates and sulfuric acid. The acid and lead create a chemical reaction. This reaction produces electricity.

• Affordable: These batteries are cheaper than others.
• Reliable: They have been used for many years.
• Maintenance: Some need regular checks and water refills.

Standard lead-acid batteries are suitable for normal driving conditions. They work well in most climates. They are easy to replace and find.

Agm Batteries

AGM batteries stand for Absorbent Glass Mat. These are more advanced. They use a glass mat to hold the acid. This makes them spill-proof and safer.

• Durable: They last longer than lead-acid batteries.
• Maintenance-Free: No need for regular checks or water refills.
• Performance: Better in extreme weather conditions.

AGM batteries are ideal for off-road driving. They handle vibrations better. They are also great for vehicles with extra electronics.

Here is a quick comparison:

Feature	Standard Lead-Acid	AGM Batteries
Cost	Lower	Higher
Maintenance	Required	None
Durability	Average	High
Performance	Standard	Superior

Both battery types have their own uses. Choose the one that fits your needs best.
