The Subaru Impreza is a very popular vehicle thanks to its ample power under the bonnet and reasonable fuel consumption all within a reasonable budget. These cars are built to last for years, so you will likely have to change out your battery at least once.
When choosing a battery to install in your Subaru Impreza, you will want to choose a reliable one with good reviews and features.
Here are The Best car Batteries for Subaru Impreza
Optima Batteries 8020-164 35 RedTop Starting Battery
Optima 8020-164 35 RedTop batteries are designed to provide a consistent and high CCA from the signature Optima six-pack, cylindrical cell design. Cells are made from 99.99% pure lead plates spirally wound and coated with lead oxide. A fine fiberglass mat separates the lead plates and holds the sulfuric acid electrolyte, making the battery spill-proof.
The battery provides 720 cold-cranking amps (CCA) and holds a reserve capacity of 90 minutes, to keep you powered uninterrupted. High cold-cranking amps make the battery suitable for use in cold, even icy, or sub-zero weather.
The Optima 8020-164 35 RedTop battery has a capacity of 44Ah which is more than enough for your Subaru Impreza.
Batteries made with pure lead plates with a fiberglass mat separator are called Absorbed Glass Mat or AGM batteries. AGM batteries offer many advantages over regularly flooded lead-acid batteries such as providing more power in short bursts. Fiberglass mats with electrolytes reduce the resistance in them to give short bursts of power at a higher rate.
AGM batteries also have the advantage of being maintenance-free, since the battery is sealed, you will not need to add distilled water or electrolytes. AGM batteries last longer than conventional batteries while providing advanced vibration and shock resistance.
You will receive 36 months warranty coverage with your purchase, during which time the battery will be replaced due to manufacturing defects.

Odyssey 35-PC1400T Automotive and LTV batteries provide 850 cold-cranking amps. This high CCA makes the battery excellent for those who live where temperatures get below zero. The Odyssey battery has a high reserve capacity of about 100 minutes. You will also get 55Ah.
The Odyssey 35-PC1400T Automotive and LTV batteries are maintenance-free and spill-proof, like all AGM batteries. The spill-proof design improves safety and mounting flexibility. The compact, tightly fitted lead plates and fiberglass mat increase vibration resistance.
The battery can be fully recharged in just a few hours. You can expect a long service life from the Odyssey 35-PC1400T Automotive and LTV Battery.
A few things to be aware of: the battery is bulky, heavy, and pricey.
The high price is, however, worth it. The Odyssey 35-PC1400T Automotive and LTV Battery offer many features that are great for any car owner.
NorthStar Pure Lead Automotive Group 35 Battery NSB-AGM35
NorthStar Pure Lead Automotive Group 35 Battery NSB-AGM35 is another AGM battery providing excellent vibration and shock resistance. AGM batteries also provide optimal starting performance at high levels. You will not have to worry about maintaining this battery as AGM batteries are spill-proof.
Because of its extremely low self-discharge rate, the NorthStar Pure Lead Automotive Group 35 Battery NSB-AGM35 has a long expected lifespan. The battery service you currently enjoy is likely to last for quite some time.
NorthStar Pure Lead Automotive Group 35 Battery NSB-AGM35 has a capacity of 60Ah and produces 740 cold-cranking amps. The reserve capacity is high at 115 minutes.
The provided extended warranty lasts for 48 months. It also has a high-level BCI rating, an assurance that it is reliable, durable, and safe.
Arc-Angel Group 35 LiFePO4 Battery
Arc-Angel Group 35 LiFePO4 Battery is a lightweight powerhouse that produces 900 cold-cranking amps. It has a capacity of 40Ah.
The Arc-Angel Group 35 LiFePO4 Battery is a Lithium Iron Phosphate (LiFePO4) battery. This means it has LiFePO4 as the cathode material and a graphitic carbon electrode as the anode. While the energy density of this battery is lower than other options, it is less toxic, less expensive, has a well-defined performance, and provides long-term stability.
The Arc-Angel Group 35 LiFePO4 Battery has an extra-low self-discharge rate and horsepower draw from the alternator is less than other conventional batteries thanks to its higher efficiency. This means it charges faster and weighs less than AGM batteries.
It also offers heat, shock, and vibration resistance, and will not give you gas issues.
You get 10 years of coverage with your warranty; this is just exceptional for the category. You also get a package that is half the weight of other batteries while it provides up to 4 times the charge cycles.
The biggest downside with this battery is how expensive it is. It is honestly hard to justify.
How to Choose the Best Battery For Subaru Impreza
This may seem obvious to you now but when you encounter some of the prices commanded by some batteries while shopping, you may start to think second-hand or an unused one from a few years ago. Older batteries, however, have one major disadvantage over new, they lose their ability to hold a charge with age. As batteries age, the construction materials slowly degrade. The components responsible for holding the charge do not last forever. If you buy an old battery, be assured you will be buying another one before too long.
Read the Reviews
Products with many reviews show a purchase history and how people have reacted to the product. It is no different for batteries. Read reviews and check consumer communities. If there are red flags with a vendor, battery, or manufacturer, someone will have encountered the problem and written about it.
Subaru Impreza utilizes batteries in group size 34. Group 35 batteries have the dimensions of 230mm X 175mm X 225mm, as dictated by the Battery Council International.
There are two major categories of batteries; namely AGM and flooded.
Absorbed Glass Mat (AGM) batteries are constructed with pure lead plates with a special fiberglass mat placed in between them. This construction gives the batteries vibration resistance, a high CCA, high capacity, and long life.
Flooded lead-acid batteries share many features with AGM batteries, except the fiberglass mat is absent.
Take the power requirements of your Subaru Impreza when shopping for a new battery. All the electronics in your car will draw power from the battery. A higher capacity will serve you well for a long time.
The best batteries will have the longest life. They should also be able to withstand harsh conditions like sub-zero temperatures, hot weather, and vibrations.
Cold Cranking Amps
Cold-cranking amps measure how fast a battery can start at different temperatures. This measurement is very important, especially if your car will be driven in very cold temperatures. A high cold cranking amp will start your car even in sub-zero temperatures.
Having a warranty will save you a lot of trouble in case of any fault. You can have your battery replaced if it is still within the warranty period. Many batteries will have 4 years of warranty, some will have fewer years while others may even have up to ten years.
