For certain device operations, special types of batteries, such as H6 and H7 batteries, are also important to use for different devices. These two come with the same width and height and a difference in length. H7 and H6 are car batteries that are commonly used for providing high-power features. In this post, we will go over H6 and H7 features to find differences. So let’s get started with H6 vs. H7 Battery.
What are H6 batteries?
- The H6 battery, also called group 48, L3, and 66L3 battery, is the main component of automobiles, maritime, and light-based devices.
- It is best to use it as a starting battery or also a dual-purpose battery for electric and electronic devices.
- The H6 battery is a modern AGM battery that does not need maintenance or shock resistance; it provides and also has vibration resistance.
- The dimensions for this battery are 278 x 175 x 190 mm, which are the same as EN 66L3 batteries.
- The main uses of H6 batteries are in standard automobiles and modern vehicles.
- • The H6 battery comes with good deep cycle features and high cranking power and is made with absorbent glass mats (AGMs).
H7 Batteries
- The H7 battery is used for cars and controlling devices in trucks. H7 comes with two main types: starting and cranking and dual-purpose.
- The H7 battery is like group 94R batteries and is also called the L4 and LN4 battery.
- The group 94R battery is employed as an H7 battery. H7 battery dimensions are 315 x 175 x 190 mm, and the dimensions for BCI Group 94 R are so we can replace H7 and BCI Group 94 R batteries.
H6 vs H7 Basic Differences
Size
- • The H6 battery, also called the group 48 battery, comes with dimensions of 11 inches, 7 inches wide, and 7.5 inches taller. The small-sized features help to use the battery for small spaces.
- H7 battery dimensions are 12.4 inches in length, 6.9 inches wide, and 7.5 inches in height. Its larger size makes it needed to manage more space for compartments.
Capacity
- • The H6 battery is a small amp-hour battery with a capacity as compared to the H7 battery. The vehicles that needed moderate power needed H7 best to use for providing good starting power and reserve capacity.
- • The H7 battery has good reserve power and longer working time since it has a high ampere-hour capacity. It is part of a different electronic system.
Cold Cranking Amps (CCA)
- • The H6 battery has a small CCA rating that is about 600 to 800 amps, and it is part of a standard engine size and moderate climates.
- H7 battery CCA value is 800 to 950, and in cold conditions has good performance and larger engines that provide good starting power for cold conditions.
Weight
- H6 batteries are low weight and small in size and are used for easy handling and installation since they have a small size and capacity.
- H7 has a larger capacity battery, is larger in size, and is heavier in weight. So it provides stable features and is difficult to connect.
Durability
- • The H6 battery is part of high-electrical-demand vehicles, and it has a shorter working life than the H7.
- H7 battery for difficult applications provides good durability and longevity features. They are best used for different electronic systems and start-stop technology because they easily handle discharge and recharge.
Cost
- • The H6 battery has low capacity and power ratings and is easy to afford. The H7 battery comes with high capacity, generates high power, and has advanced features. It is a higher cost than H6.
Reserve Capacity (RC)
- The reserve capacity is also different for both batteries. If the battery is not charged with the alternator, RC helps to find how many times it is used. It defines how long the battery will work.
- Standard constant amps for 25 before moving to minimum voltage. The good RC value makes the battery larger. As a result, H7 is a high cost as compared to H6.
Weight
- • The H7 battery is heavier than the H6; the H7 battery weighs 51 to 57 lbs, and the weight of the H6 is 45 to 54 lbs. Battery weight affects battery performance, and light vehicles come with extra features compared to heavyweights.
- The heavy H7 battery comes with high capacity and provides better electrical features than the H6 battery.
Nominal capacity
- Nominal capacity for a battery defines current discharge with a fully charged battery for normal conditions. The H7 battery has a high nominal capacity of about 76 to 80 Ah, and the H6 battery’s nominal capacity is 60-72 Ah.
