Battery Types

Both batteries subscribe to the Lead Acid type, specifically employing a Flooded Lead Acid design. This means they can deliver robust starting power and can generally handle a wide range of vehicles. 

However, the nuanced differences in their specifications cater to varied automotive needs, ensuring you can select a battery that mirrors your vehicle’s demands.

Reserve Capacity

The reserve capacity of a battery indicates the duration it can provide power if the alternator fails. The Everstart Maxx H6 holds a slight edge here with a reserve capacity of 115 minutes, compared to Everstart Maxx H5 100 minutes.

This means the Everstart Maxx H6 can provide power for a more extended period during emergencies.

Cold Cranking Amperage

Cold cranking amperage (CCA) denotes the ability of a battery to start an engine in cold temperatures.

The Everstart Maxx H6 battery boasts a CCA of 730, whereas the Everstart Maxx H5 model comes with a 650 CCA. The Everstart Maxx H6 might be the preferred choice for those living in colder climates.

Cranking Amperage

When it comes to cranking amperage, which is the amount of current a battery can provide at 32°F, the Everstart Maxx H6 again takes the lead with 900 Amps, while the Everstart Maxx H5 delivers 800 Amps. This signifies that the Everstart Maxx H6 can provide a stronger initial boost.


Both batteries operate at a voltage of 12 Volts, ensuring a standard and reliable power output suitable for most vehicles.

Group Size

The BCI group number indicates the physical specifications and fit of the battery. The Everstart Maxx H6 belongs to Group 48, and the Everstart Maxx H5 is part of Group 47.

This classification will be essential when determining the right fit for specific vehicle models.


Regardless of your choice, both batteries come with an impressive three-year free replacement warranty, ensuring peace of mind for the consumers.

Dimensions LxWxH

The Everstart Maxx H6 measures 10.94 x 6.89 x 7.48 inches, making it slightly longer than the Everstart Maxx H5, which comes in at 9.50 x 6.94 x 7.50 inches.

This slight difference in size might matter depending on the space constraints of your vehicle.

Terminal Location

The positive terminal is located on the top left for both models, ensuring easy accessibility and a standard connection setup.


When it comes to weight, there’s a negligible difference, the Everstart Maxx H6 weighs in at 40 lb, and the Everstart Maxx H5 is just slightly lighter at 39.52 lb.

Important Features

Both batteries are maintenance-free, guaranteeing minimal hassle post-purchase. They also both offer free battery testing and installation at Walmart Auto Care Centers.

An environmentally-conscious perk is the free lead acid battery recycling available at Walmart for those looking to dispose of their old batteries responsibly.

Our Observation
Upon close examination of the two EverStart Maxx Lead Acid Automotive Batteries, I’m intrigued by the value these batteries seem to offer. Both Group Size H6 and H5 retail at the same price, yet the Everstart Maxx H6 variant delivers a slightly higher cold cranking amp (730 CCA) compared to the Everstart Maxx H5 650 CCA.

The Everstart Maxx H6 also boasts a longer reserve capacity of 115 minutes versus the Everstart Maxx H5 100 minutes. What’s commendable is the 3-year free replacement warranty on both, assuring reliability. Additionally, the convenience of free testing and installation at Walmart Auto Care Centers and the environmentally conscious effort to offer free lead acid battery recycling is appreciable.

From a weight and size perspective, they’re comparable, making the choice largely dependent on specific vehicle compatibility and power requirements.
