WeRV Power powered by Prime Battery Solutions

Group 24 vs Group 27 battery

A BCI group number mostly tells you the case size and the terminal layout. Capacity, CCA and battery type still vary by product.

WeRV Power answer

Compare battery group sizes without mixing up the case size with the battery type or how it performs.

What to check

Treat the result as a planning range. The exact fit and the install still get checked against the vehicle, the equipment and the battery maker.

  • Measure the tray length, width and height
  • Confirm which way the terminals face
  • Compare capacity and CCA on the actual labels
  • Check the hold down and the cable reach
