- Group size helps users and manufacturers to find battery types for certain dimensions and features to provide the required features.
Group 27 battery dimensions
- Group 27 battery comes with a 12.1inches length and 6.8 inches mm width with a height is 8.9 height. There can be chances of minor differences between dimensions for different manufacturers.
Group 27 battery types
Group 27 Flooded Lead-Acid Batteries
- Flooded lead-acid batteries are common types of group 27 batteries. That comes with liquid electrolytes, and it needed proper maintenance, like checking and topping off the water level. It is a low-cost battery and is highly used. It avoids spills and leaks by keeping upright.
Group 27 Sealed Lead-Acid (SLA) Batteries
- The sealed lead acid battery comes with an absorbent glass mat and gel battery and uses low maintenance, and we can connect in any direction. AGM battery has a fiberglass mat that helps to absorb the electrolytes, and it provides spill-proof and resistance to vibration. Gel batteries use silica gel that helps to immobilize electrolytes and provide deep discharge and longer working life. It is safe and needs low maintenance as compared to flooded lead-acid batteries.
Group 27 Lithium-Ion Batteries
- A lithium-ion battery is the latest type of group 27 battery and has high energy density and low weight features for longer working life. Lithium-ion batteries require low maintenance and have a high discharge rate and are best for applications where weight and efficiency are important. It does not have any lead or acid components that make it less hazardous for the environment.

Group 24 battery vs. group 27 battery
Chemistry
- Both 24-battery and group 27-batteries Both uses most BCI group common chemistries that are Sealed Lead Acid (SLA), AGM Absorbent Glass Mat (AGM) batteries, flooded batteries, and lithium-ion batteries.
- Lead-acid batteries are a low-cost option, and lithium batteries have a longer working life and are mostly used for recycling and environmental applications.
Dimension
- The dimensions for the group 24 battery are 10.25 x 6.8125 x 8.875 inches, and the group 27 battery dimensions are 12.0625 x 6.8125 x 8.875 inches, or 306 x 173 x 225 mm.
Capacity
- The capacity of a group 27 battery is higher as compared to a group 24 battery. The battery group that has a high number comes with more amp hours as compared to the low number.
Application
The common uses for Group 24 batteries are backup storage systems, large UPS systems, medical and security systems, industrial applications, and wheelchairs.
The Group 27 battery is used for RVs, marine uses, and other such uses.
Are Group 24 batteries and Group 27 batteries interchangeable?
- For doing that, first check your device size dimension that needed to replace these batteries. If the battery can fit in the device or vehicle, also check that it can provide the required power. The group 27 battery is larger in size than the 24 battery. So it has high power; if there is no size problem, we can use it interchangeably.
What is the main difference between Group 27 and Group 31 batteries?
- Group 27 batteries are small and have a lower capacity than group 31 batteries. Group 31 batteries are larger in size and have high power and are used for heavy-duty applications like trucks and large boats.
