«I've had installed in CT200H for well over a month now and it both fits and has worked perfectly. I received it quickly and everything went very smoothly. Recommend both the company and the battery!»

«Algo más baja que la original, el ancho y el largo son equívocos. No me entró en el hueco de la sustituida por el ancho...se deberían indicar las medidas máximas reales...»

Frequently asked questions
- It depends on the engine. Lexus RX owners mostly buy Varta B31 Dynamic SLI 45Ah (47.60 €), Varta A7 Dynamic AGM 70Ah (122.95 €) and Varta D47 Dynamic SLI 60Ah (69.95 €) 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.
- 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.
- 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.
- On most versions, yes: disconnect the negative terminal first, then the positive, release the clamp and fit the new battery in reverse order. On Start-Stop models or cars with battery management (BMS), register the new battery with a diagnostic tool so the ECU adjusts charging.
- Typical signs: sluggish cranking in the cold, headlights dimming on start-up, a battery warning on the dash or electronics resetting. A workshop can check resting voltage (below 12.4 V means discharged) and cranking capacity in a minute.
