Group 51 equivalent sizes
These BCI groups share a near-identical case, so they may fit the same battery tray. “Same terminals” means the +/- posts sit on the same side; reversed terminals (R groups) can leave your cables short.
| Group | Case (mm) | Terminals |
|---|---|---|
| Group 51R | 238×129×223 | reversed |
