Our Product Unboxing Journey:

I was going to buy a big, bulky battery for my car when I found out about Northstar.   I ordered two Northstar’s batteries for my car. They arrived very quickly and I was able to install them with no problems at all! The installation process was easy to understand and the instructions were simple to follow. My car has been running great ever since I installed the battery.  The Delivery time was fast and very efficient. I received the Northstar’s battery two days before the estimated delivery date which was wonderful!  I’ve had the product for over a month now and it’s still working great. I’m very pleased with this battery and would recommend it to anyone looking for an easy replacement option!

Know Everything about Northstar Batteries – Buying Guide:

So here are all the facts and features in detail so you could buy the new model of the best Northstar’s battery for your car.

Know your Battery Type:

Since there are different types, it’s important to know which type you need. If your battery is a kind of AGM battery or flooded cell battery, Northstar is the perfect option to choose! Northstar specializes in these top 2 battery types. Pure Lead AGM batteries will sulfate to much less a degree than a flooded battery.

Conventional Batteries:

Northstar’s offers a 12-volt conventional battery in Group 31, 32, 34 and 35 sizes.

AGM Batteries:

Northstar offers a range of 12-volt batteries for cars. The 12-volt Group U1 or 8D AGM batteries that have been designed for the running of cars have a very long lifespan with proper usage and maintenance. In addition to these, Northstar also offers 6-volt, 2H Northstar AGM batteries which are fitted to tractors and marine vessels.


All batteries have a positive terminal, negative terminal, and binding posts that allow electricity to flow through. If the posts on your vehicles are not labelled, it’s usually a good rule of thumb to refer to the size and type of your current AGM battery.

The Reserve Tank:

Every Northstar battery has a reserve tank, inside of which is distilled water. If you ever need to add more fluid, all you have to do is remove the cap located over the vent, and add about 1/2 cup of additional distilled water through the opening.

Battery life:

All thanks to the AGM technology, as every Northstar’s Battery discharge has a 1,000-hour discharge rate. This means that if you use 50% of the battery’s power every hour, it will last for 1,000 hours. In most cases, Northstar’s battery can handle this kind of powerfully charged. The battery doesn’t just withstand terrible weather conditions; it can also withstand heat temperature.


North star batteries offer a three-year warranty on all products. This means you can replace your pure lead battery for free if it is not working within a three-year period.

Charging the Battery:

It’s important to know how to properly “charge” your devices because bad, overcharging batteries can actually short circuit and even catch on fire!


•Use a charger that is compatible with your battery type (Northstar pure lead offers both flooded cell and AGM chargers).

•Charge in temperatures between 75-90 degrees Fahrenheit with a high CCA rating.

•Unhook or turn off your charger when it’s not in use even with high cost.


•Leave your charger connected when not in use.

•Let your battery charge for more than 48 hours without checking on it.

Final thoughts:

North star offers a lot of benefits that aren’t found in other batteries. Unlike other competitors, they last even longer than the standard models (around double the number of charges). This means your battery could go for months or years and you never have to worry about buying another one!
