## How to know which battery your Buick Regal takes

The real shortcut is your registration number. It settles generation, engine and factory battery in seconds — exactly where most people get it wrong when buying.

You can also work it out yourself: find the registration date in the vehicle documents and locate it in the table. If the year overlaps two generations, the body style — hatch, estate or coupé — tells them apart.

One last check: the label on the fitted battery gives you the reference capacity and cold cranking. Match or improve those numbers, and make sure the case size and polarity suit your battery tray.

## Frequently asked questions

### Which battery does a Buick Regal take?
It depends on the generation and engine: there are 1 compatible batteries in total, from 44 to 44 Ah and 730 to 730 A of cold cranking. The best sellers for this model are Car battery Optima RTU-3.7 12V 44Ah 730A AGM. With your plate we tell you the exact one in seconds.

### How much does a Buick Regal battery cost?
Between 187.30 € and 187.30 €, VAT included, depending on capacity and technology (AGM). Start-Stop versions (AGM or EFB) sit at the top of the range because they withstand many more cycles.

### How do I know which generation my Regal is?
By the registration year: Regal (1997-2008); Regal Coupe (1990-1996). If your year falls in the overlap between two generations, tell them apart by body type (hatchback, estate or coupé) or use the plate finder, which settles it with no doubt.

### Can I fit a battery with more amps?
Yes, as long as the dimensions fit the tray and the terminal layout matches. More capacity (Ah) and more cold cranking (A) do not harm the vehicle: the alternator charges it the same and you gain margin in winter. What you must never do is go below the original figures.

### How long does a Buick Regal battery last?
Between 4 and 6 years in normal use. Start-Stop batteries (AGM/EFB) tend to last slightly less in city driving because of the number of starts, but they are designed for that cycling. If the car sits unused for weeks or you notice slow cranking in the cold, get it checked.
