## How to know which battery your Cadillac BLS 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.

Prefer to do it manually? Check the date of first registration on your V5C and match it against the generation table above. When a year straddles two generations, the body style decides it: five-door hatch, estate or coupé.

Before ordering, inspect your existing battery: its label lists the Ah and the starting amps. The replacement must match or beat both — never fall short — and share the same size and positive terminal side.

## Start-Stop: which battery your BLS needs

Start-Stop on the modern BLS changes the rules: the battery takes hundreds of micro-cycles daily. The correct answer is EFB for basic systems and AGM where braking energy is recovered. Dropping to a conventional battery is the most expensive mistake you can make here.

## Frequently asked questions

### Which battery does a Cadillac BLS take?
It depends on the generation and engine: there are 3 compatible batteries in total, from 70 to 77 Ah and 680 to 780 A of cold cranking. The best sellers for this model are Car battery Varta E11 12V 74Ah 680A, Car battery Varta E44 12V 77Ah 780A, Start-Stop battery Varta A7 12V 70Ah 760A AGM. With your plate we tell you the exact one in seconds.

### How much does a Cadillac BLS battery cost?
Between 79.13 € and 148.78 €, VAT included, depending on capacity and technology (lead-acid, 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 BLS is?
By the registration year: Bls Wagon (2007-2025); Bls (2006-2025). 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 Cadillac BLS 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.
