Car Batteries

Which starter battery is right for my car?

The easiest way is to use the data of your old battery. Make a note of the capacity, voltage, base strip and circuit. For 100% accuracy you should measure the size (length, width and height) of the old starter battery. With this data you can easily find the right starter battery.

You don't know what to do? Then send us pictures of all sides of the old battery. We will be happy to you find the right starter battery.

What is the difference between the battery technologies?

● Acid: Inside the battery is liquid acid which should be refilled at regular intervals - this is usually the cheapest price variant. Most of our autmotive batteries are sealed maintenance free
● AGM (Absorbent Glass Mat Technology): In AGM batteries, the electrolyte (acid) is completely bound in a glass fibre fleece, so the batteries are leak proof - medium price variant.
● GEL: The acid in these batteries is thickened to a gel. Like the AGM battery, they are leak proof and extremely durable - high-quality price variant.

What is the delivery time of a starter battery?

Our starter batteries are packed and dispatched directly after your order by our automated packing line. The delivery time is between 1-3 days. If you need further information about your order, simply contact our service team. Or use the shipment tracking.

Can I return my old battery?

You can return the old battery in our shop. Alternatively, you can dispose of the used battery at a recycling centre or scrap dealer.  Important: Ensure the respective company provides confirmation about the disposal of the old batteries. Then send the confirmation via our refund form.

How can I recharge the battery?

The starter battery is automatically recharged during a longer journey by car. If you want to recharge the car battery for a longer period of time, use a charger.

How long does it take to fully charge my starter battery?

The starter battery is recharged by the alternator while driving. The starter battery cannot usually be charged enough during frequent short distances.  In order for your new starter battery to last longer, you should fully charge it by driving for longer journeys or using an optional charger.

How do I know the correct connection (terminal arrangement)?

The easiest way is to use the data from your old battery. Or refer to your car owner's manual.

What voltage does my car need?

Almost all cars use 12V voltage. Trucks usually have 24 Volt voltage systems. If you are unsure, check your old battery or your car's manual.

What capacity do I need?

To choose the capacity you should use your old battery as a template. If you are unsure, check your used battery or your car manual.

How do I know if I have Start-Stop?

Many new cars switch off the engine when stationary. When choosing the right car battery, please make sure that your car also has an automatic Start-Stop function. For further information, please refer to your vehicle manual.

What is the base hold down of the battery in my car?

Most cars use the B13 baseboard. Check your old starter battery to see which hold down you need. Or take a look at your car's manual.

Can I also ship to locker courier service?

No, our starter batteries cannot be sent to locker courier service.
