Battery Types

The Everstart Maxx H7 belongs to the Lead-acid type of battery- these batteries come with a structure of metal Lead-based alloy plates flooded in an electrolyte solution. This is probably the most common type of automotive battery. This type of battery, mainly the H7, is cost-effective and affordable.

The Everstart H8 belongs to the Lead-acid group as well. Like the typical lead-acid batteries, this one is built with a robust design. It specializes in tolerating overcharging and is built to last for really long. Also, this particular model is extremely priced effective and is highly recyclable.

Reserve Capacity

The Everstart H7 is satisfied with its RC (reserve capacity) rating- it features 130 minutes of reserve capacity, which eventually means that until the voltage decreases, this 12v battery can provide 25 amperes for 130 minutes of 10.5 volts. This battery will run your vehicle for almost 130 minutes in case of alternator failure.

Everstart H8 features 160 Reserve Capacity, which means this battery can provide 25 amperes at 10.5 volts for 160 minutes until the voltage decreases. As the reserve capacity of this battery is more than the H7, this one can provide power to the alternator for a longer time.

Cold-Cranking Amperage

CCA or Cold Cranking Amperage is defined as the number of amperes in a temperature of 0F. A 12v battery can deliver, maintaining the least 7.2V voltage for 30 seconds at a stretch. The Everstart H7 comes with 790 CCA which means in cold temperatures, and this one will be highly helpful due to its high starting power.

The Everstart H8 is mind-blowing as it flaunts 900 CCA when it comes to CCA. The higher the cold cranking amperage for car batteries, the better it will work in winters or cold areas. Thus, if you belong to the world’s coldest areas, the H8 model would be the first pick.


The Everstart H7 is built with 12v, which signifies the standard voltage parameter for a decent battery. It causes the least trouble to the alternator and provides as much support as possible. Due to the standard voltage, the car never needs a hard start, ensuring the engine’s durability.

The Everstart H8 follows the same voltage as the H7; it also features 12v. As the voltage is decent enough to run the car alternator properly, it also eliminates extra pressure. This voltage ensures the safety of the hardware such as the sensors, and prevents any further damage.

Dimensions LxWxH

The Everstart H7 features 12.40 x 6.90 x 7.50 inches which is a standard dimension for a lead-acid battery. It is standard for cars and light vehicles as well. As lead-acid batteries’ performance is proportional to their sizes, this dimension ensures proper cold-cranking amperage, reserve capacity, and other measures for a standard battery.

The Everstart H8 is larger than the H7, 13.90 x 6.90 x 7.50 Inches is the dimension of this model. As 1.50 inches bigger in length than the H7 one, it may be able to take more load than the previous model. Though this one also works better with light vehicles, this one is also superior in performance due to the bigger dimension.

Group Size

H7 is the DIN code for the Everstart Maxx H7 battery, also known as L4 or 77L4, and as per the BCI labeling, the H7 dimension is pretty close to the 94R group. The dimensions of these groups are H7: 315 x 175 x 190 mm, and 94R: 315 x 175 x 190 mm.

So, the dimensions are the same, and the H7 battery belongs to the 94R group. The group size in any battery is significant to finding the perfect fit for your car. Users must check the car manufacturer’s manual to determine the battery group size Suitable for their vehicle. However, any car or vehicle that supports group size H7 or 94R must opt for the Everstart Maxx H7 battery.

Similarly, H8 is the DIN code for the Everstart Maxx H8 battery and is also labeled as L5 or 88L5. It features a similar dimension to the BCI 49 group of batteries. The dimensions are H8: 354 x 175 x 190 mm, 49: 381 x 175 x 192 mm. Although the width and height are quite similar, the 49 group is slightly longer than the H8. Thus the H8 battery can be a replacement for the group 49 battery, but the group 49 battery cannot replace the H8 battery.


Both the Everstart Maxx H7 and H8 come with three years free replacement warranty. Suppose the customers feel any problem within the first three years of use. In that case, they can claim a free replacement (the details are found on the warranty document). Moreover, users can enjoy free battery testing.

Terminal Location

Everstart Maxx H7 and H8 locate the terminals in the same position. Both these batteries are top post batteries. Thus, it becomes easy to connect positive and negative terminals. It features a positive terminal on the right side at the top of the battery. While buying any battery, the buyers must know about the terminal location and determine whether the location is suitable for their vehicle cable or not.


The Everstart H7 weighs around 50.9 lbs. which is way more than the standard weight for any car battery. For lead-acid batteries, more weight means more constituents. Thus, heavyweight batteries are considered better. The Everstart H8 weighs 59.2 lb, almost 9lbs more than the Everstart H7. Therefore this battery is more suitable for heavy-duty power engines.

Our Observation

The main difference between Everstart Maxx H7 and H8 Battery is in the Reserve Capacity. Everstart H7 has 130 minutes of reserve capacity, and Everstart H8 has 160 minutes of Reserve Capacity. It is observed that the H8 battery is better in almost every aspect than the H7 battery.

Although both these batteries come with a three-year free replacement warranty, the H8 battery is more powerful and has a longer lifespan. So, if you are looking for a better battery, the Everstart Maxx H8 is the way to go.
