Group U1 battery: equivalents & cars that use it
A BCI Group U1 battery measures 197×132×186 mm (L×W×H). The closest equivalents that fit the same tray are Group U1R - always confirm terminal side and CCA before swapping.
What to look for in a Group U1 battery
| Case size (L×W×H) | 197×132×186 mm |
|---|---|
| Typical CCA | 200-350 CCA (aim for 200+) |
| Chemistry | AGM (fitted from the factory) |
| Vehicles using it | 10 across 1 make (2016-2020) |
Computed across the 10 Group U1 vehicle-years in our verified dataset - a large sample of popular US models, not the entire fleet.
Buying a Group U1 battery
Match the group size (Group U1) and aim for at least 200 CCA - more in cold climates. Every Group U1 car in our data ships with an AGM battery from the factory - do not fit a standard flooded one. A battery is heavy to ship, so buying in person can win once you count free install and the core-charge refund - but to compare prices and reviews:

Group U1 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 U1R | 197×132×186 | reversed |

Frequently asked
How many CCA does a Group U1 battery need?
Group U1 vehicles in our data ship with 200-350 CCA (typically around 200). Match your car's original rating or go higher - aim for the top of that range in cold climates.
Is a Group U1 battery AGM or flooded?
Every Group U1 vehicle in our data uses an AGM battery from the factory. Fit AGM - do not downgrade to a standard flooded battery, which can fail early and confuse the charging system.
What size is a Group U1 battery?
A BCI Group U1 case measures 197×132×186 mm (L×W×H). Any Group U1 battery uses that footprint, so it drops into the same tray.
What is equivalent to a Group U1 battery?
The closest BCI sizes that fit the same tray are Group U1R. Always confirm the terminal side and CCA before swapping - a reversed-terminal group can leave your cables short.
