Varta batteries

VARTA starter batteries provide the energy that is needed at all times regardless of the vehicle in which it is installed, the terrain and designed to withstand the most extreme vibrations. All this with the reliability and guarantee of VARTA as a leading manufacturer of starter batteries for motor vehicles.

Choose the correct auxiliary battery

Check the fitted battery part number, installation space, terminal orientation, connections and hold-down. A vehicle may use different batteries according to version and equipment. Matching voltage or size alone does not establish compatibility.

Ratings to compare before ordering

Ah is nominal capacity and A is the cold cranking current given in the manufacturer’s data. These are different ratings and do not make an auxiliary battery a universal replacement for a main starter battery.

Replacement and charging

Follow the vehicle manufacturer’s procedure for disconnecting and replacing the auxiliary battery. Adaptation or diagnostics may be required. Use a suitable battery charger and consult a qualified professional if the procedure is uncertain.

Price, availability and online ordering

Check the price and delivery options on this page. The total and delivery charges are confirmed in the basket before ordering. Compare the ETN part number and dimensions before buying to avoid an unsuitable replacement.

Frequently asked questions

Is this the main starter battery?

This part belongs to the auxiliary range for dual-battery systems. Confirm its role and application against your vehicle’s requirements.

Has Silver Dynamic Auxiliary been renamed Dynamic AUX?

VARTA has updated this range name to Dynamic AUX. Use the short code and ETN to identify the replacement rather than relying only on the packaging image.

Mercedes SL 55 AMG auxiliary battery

The service and handling were perfect, but when the courier delivered the battery, the box had tipped over and there was visible liquid seeping onto the cardboard and the battery itself. I contacted customer services. A very friendly lady (Cristina) dealt with me; I explained the situation to her and she told me there shouldn’t be any problem. I hope that’s the case, but if there is a problem, I’d like to be sure that a replacement is provided. neither the supplier nor the customer is at fault here; in this case, it is the courier company.
