Benefits of Buying the Product

Why North Star Battery is the Best?

Now, you must be thinking, why the NorthStar is exceptional and if you should buy them. Would this be better than the brands like- Optima or Vmax? These are the reasons that make the NorthStar batteries outstanding at what they do.

Extended Battery Life and Reserve Capacity

Thin plate NorthStar AGM batteries can last up to 12 years if maintained properly. In addition to that, NorthStar has an excellent backup capacity in each of its products. They exceed other products in this category.

High CA and CCA Rating

With a high cranking rating, the battery kick starts an engine under any environmental condition. NorthStar has an outstanding rating in this sector. Therefore, you shouldn’t hesitate when choosing a NorthStar product if you live in the northern or southern parts of the world, where it freezes in the winter.

Lightweight Feature

We all know batteries are heavyweight. But where the NorthStar stands out among the competitors is its lightweight. Therefore, they are easier to carry from place to place. And lightweight batteries are great for boats as it betters the performance of the boat. NorthStar batteries are relatively lighter than most batteries out there.

No Leakage!

The NorthStar batteries don’t leak like other batteries. Some batteries spill when the vehicle falls into an uncontrolled environment. But with the NorthStar, the chance is the least. That’s what makes them great.

Exeptionally Made.

The make of NorthStar is exceptional. The manufacturer provides the best quality plastic, which is heat and vibration resistant and prevents damage to the battery core.

Made in the USA

This is another factor people often get curious about. NorthStar produces its batteries in two production facilities in Springfield, Missouri. So, it’s entirely made in America. They don’t make their product with cheap materials in another country. You are guaranteed to get American-made batteries from NorthStar.

That’s how NorthStar stands out from other battery producers. They produce not only great batteries but also provide excellent after-sales service.

Buying Guide for Northstar Battery

What Should You Consider When Buying a Battery?

You need to understand a few things need before you shop for a car or marine battery. Here are the factors that make the difference between a good battery and a great battery.

Battery Type

Well, batteries have a variety of sizes, shapes, and weights. Also, they are different in capacity. More importantly, batteries come in three different forms- lead-acid, AGM/ Absorbed Glass Matt, and Lithium-iron-phosphate or LiFePO4. You must know what type of battery you need for your particular vehicle or marine craft.

Service Life

One of the most significant aspects is to consider before buying a battery. The service life of the battery determines whether it is worth spending money on it.

Heat and Vibrant Resistance

Heating issues are typical for a car battery, especially when it gets old. The excellent quality battery must have resistance against heating. Also, vibration can cause damage to the batteries at a significant level, whether by spillage or dysfunctioning the materials. The vibrant resistance capability is another aspect to look for when buying a great quality battery.

Reserve Capacity

Reserve capacity or reserve minutes is the number of minutes a battery can give back up when fully charged before it gets fully discharged—the greater the number, the better the battery capacity.

Depth of Discharge or DoD

Depth of discharge is the level at which a fully charged battery can be Depth of discharge is the level at which a fully charged battery can be discharged. Depth of discharge or DoD is expressed in percentage. You can say it’s the exact opposite of the state of charge. DoD in AGM batteries goes up to 50%, and for Lithium-iron-phosphate or LiFePO4 or LFP batteries, it’s about 80%.

Battery Cycle

One battery cycle counts when a battery is fully charged and then fully discharged. There is a connection between the battery cycle and charging. The more you charge and discharge the battery, the life expectancy of the battery is reduced. So, we suggest charging the battery fully and discharge it at the recommended level before charging it again to get the best value. The highest cycle goes up to 1000 when the least could be 300.

Acid Leakage

Any poorly made battery would leak acid at a point in its lifetime. Acid leakage not only ruins the surroundings of the battery it may also damage your skin or clothes. However, a quality product would never do such a thing. In the case of batteries, you should pick a battery that has the slightest possibility of acid spillage.

Charging & Maintenance Instruction

1. Store the battery in a fully charged state. Thus, you can reduce the chance of the battery dying or losing its capability by getting deeply discharged.

  • The battery may get discharged in many ways. If you store it for a long time in a low state of charge, the battery charge gets drained in time, eventually ruining the capacity. 
  • Another way the battery remains undercharged is when you discharge it entirely beyond its discharging limit or depth of discharge without fully charging it before.

2. Overcharging is as harmful to a battery as undercharging. When you overcharge a battery, the heat produced during the process reduces the battery capacity and can even kill it.

3. Overwatering or underwatering can also damage the battery. The lead-acid battery requires watering to prevent acid build-up and gassing. If you don’t water the battery regularly, it keeps losing water when charging, and it will eventually dry. In the case of overwatering, excess water might reduce battery performance.

4. Water the battery when in a discharged state.

5. Read the manufacturer’s guidelines correctly. Follow the manufacturer’s guidance for a particular battery type and instructions to maintain the battery in a healthy state. Reading the user’s manual is essential when using a battery as the batteries may differ in functionality. You can ask the customer support officer for help regarding the battery.

Frequently ask Questions

1.     Where Can the Batteries Be Used?

Auto batteries kick start a vehicle engine. It can be used on cars, RVs, trolling motors, marine boats, trucks, and other vehicles. And it can also be used to power up the inverters and generators at home.

2.     What is the average cycle life of NorthStar batteries?

NorthStar batteries have an extended capacity than the competitors when it comes to life expectancy. These batteries have four times more life expectancy than a flooded lead-acid battery and about two times more than the conventional AGM batteries. On average, a NorthStar AGM battery can last up to 12+ years. These batteries last longer due to their superb heat resistance.

3.     What Type of Guarantee Comes with a NorthStar Battery?

The NorthStar batteries may have 3 to 4 years of warranty, depending on the type of battery you’re using. However, if the shipped product has any defect, the manufacturer takes care of it by replacing or repairing it.

4.     Do NorthStar AGM batteries have to be segregated for recycling?

NorthStar batteries require no additional segregation to be recycled. You have to recycle it like the conventional AGM or flooded batteries.

5.     Why can AGM batteries sit so long without needing charging?

AGM or absorbed glass material is the type of battery where the elements are in gel form. Therefore, there is no gassing due to the acid build-up. Hence, this battery type requires less charging than the conventional lead-acid batteries, and they can sit longer without being charged.

6.     Does the battery discharge when not used?

Yes! Batteries do slowly discharge when not in use. It’s called self-discharging. Also, when your car is sitting in the garage, it draws a small amount of current to keep the mechanism in your car active.

7.     Do I need to discharge them before charging fully?

Depth of discharge indicates the percentage of charge at which a battery can be discharged. Yes, it would be best to discharge the battery at the recommended level before fully recharging it. Otherwise, it will reduce the battery cycle, hence the battery life.

8.     When should you perform an Equalization charge?

You should perform an equalization charge on a flooded lead-acid battery when the gravity reading varies from cell to cell at +/- .015- to remove sulfate crystals from the battery plates.
