## Mercedes-Benz B-Class generations

Batteries change from one generation to the next. When two share a year, the body style — or simply the plate — settles it.

## How to know which battery your Mercedes-Benz B-Class 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.

Another route is the vehicle paperwork: the registration date places you in one of the generations listed. In the overlap years, body style is the detail that separates them.

As a final check, look at the battery currently fitted: the label shows capacity (Ah) and cold cranking amps (A). Always replace with equal or higher figures, never lower, and keep the same dimensions and terminal layout.

## Start-Stop: which battery your B-Class needs

The later B-Class generations run Start-Stop, which puts the battery through hundreds of micro-cycles a day. These cars require EFB (basic Start-Stop) or AGM (Start-Stop with regenerative braking): fitting a conventional battery instead cuts service life to a few months and the ECU may disable the function. Rule of thumb: never downgrade from the technology fitted at the factory.

## Frequently asked questions

### Which battery does a Mercedes-Benz B-Class take?
It depends on the engine. Mercedes-Benz B-Class owners mostly buy Varta AUX14 13Ah (70.20 €), Varta A6 80Ah (149.95 €) and Varta E44 77Ah (85.40 €) from us. The table shows the recommended battery for each engine with its price (VAT included) and a link to its page; with your number plate or VIN we tell you the exact one in seconds.

### How much does a Mercedes-Benz B-Class battery cost?
Between 70.20 € and 149.95 €, VAT included, depending on capacity and technology (AGM, lead-acid). 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 B-Class is?
By the registration year: B-Class Sports Tourer III (2018-2025); B-Class Sports Tourer II (2011-2018); B-Class Sports Tourer I (2005-2011). 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 Mercedes-Benz B-Class 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.
