Group 31 Battery Buying Guide – Things to Consider
Overview of Group 31 Batteries:
A group 31 deep cycle battery, as defined by the Battery Council International (BCI), is a battery that belongs to this group. Besides being used in vehicles, boats, and remote power sources, Group 31 batteries have also become popular. By deep cycle battery, we mean a battery that can be discharged and recharged many times.
Size or Dimension:
Group 31 designations identify primarily the battery’s size and do not give insight into its power, even though it can affect energy production. 13 inches long, 6 13/18 inches wide, and 9 7/16 inches tall are the dimensions of Group 31 batteries. These batteries are larger than those belonging to Group 29NF. On top of that, Group 31 batteries are shorter than Group 29H batteries, yet they are taller and wider as well.
The Power Ratio:
The average rated capacity of Group 31 batteries ranges between 75 and 125 Ah. There is a CCA range of 600 to 1150 amps. The lithium Group 31 batteries are capable of delivering the same level of power as the lead-acid batteries. Despite this, lithium batteries offer more charge and discharge cycles than other batteries.
Besides starting batteries and deep cycle batteries, it also offers dual-purpose batteries in group 31. In addition to being popular batteries, these models also have impressive features. Batteries that are dual-purpose perform perfectly under deep discharge.
The weight of a Group 31 lead-acid battery is usually in the range of 60 to 75 lbs. The battery weighs much more than other types. Since they are made up of a liquid mixture of sulfuric acid and water, they weigh more than lead-acid batteries. In contrast, lithium Group 31 batteries typically weigh between 28 and 30 lbs.
Group 31 battery usage:
Heavy motorized vehicles, such as ambulances, fire engines, and other heavy vehicles usually require a long-lasting, reliable battery to start the ignition, which is why groups 31 batteries are commonly used in them.
