## How to know which battery your Lexus RX takes

The quickest and safest route is to enter your number plate: we identify the exact version, its engine and the battery fitted at the factory, with no room for error.

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 RX needs

The later RX 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 Lexus RX take?
It depends on the generation and engine: there are 10 compatible batteries in total, from 45 to 95 Ah and 330 to 830 A of cold cranking. The best sellers for this model are Car battery Varta D24 12V 60Ah 540A, Car battery Varta G7 12V 95Ah 830A, Car battery Varta B32 12V 45Ah 330A. With your plate we tell you the exact one in seconds.

### How much does a Lexus RX battery cost?
Between 47.60 € and 127.30 €, VAT included, depending on capacity and technology (lead-acid, EFB). 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 RX is?
By the registration year: Rx IV (2015-2025); Rx III (2008-2015); Rx II (2003-2008); Rx I (1998-2003). 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 Lexus RX 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.
