Interstate Batteries Marine/RV Battery 12V 100Ah 925CCA 1110CA Group 31 AGM

- 12V 100Ah, Group 31
- 925CCA, 1110CA, dual-purpose
- Pure lead AGM
Our take
The most versatile AGM here for a truck-camper or boat. Choose it when one battery must do two jobs.
Why it made the shortlist
The Interstate Group 31 is a 12V 100Ah pure lead AGM battery rated at 925CCA and 1110CA. The listing calls it a 2-in-1 that delivers cranking power and deep-cycle output, built with thick plates for repeated discharge.
The listing claims a service life of 2 to 3 times conventional flooded types.
It suits boats and trailers that need one battery to start a motor and also run onboard gear. The Group 31 tray size fits many boxes.
What works
- Dual purpose: start and house
- 100Ah in a standard group size
- Pure lead plates for deep cycling
- Established brand and sizing
Watch out for
- Heavy compared with lithium
- The catch
- It is a heavy lead-acid unit, and half of 100Ah is the usable range.
