Good service, but unclear when battery was made

Excellent service, safe delivery and responsive feedback, but I asked when the battery was made and I was told this information was not available. Date code on base of battery was November 2023, so possible that the battery was over 1.5 years old. Important point as the battery is for an I-Pace that depends on this battery for braking

Excellent customer service

Ordered ~15:30 on Friday, hoping it’d arrive before job on Tuesday. Phoned to confirm this would be the case to find that, with the paid for standard delivery and my order coming in just after the cut off, my order wouldn’t ship until Monday - not to turn up on or before Tuesday. To my surprise, and without me asking or being told, my shipment method was upgraded! It arrived Monday morning! Excellent service!

Perfect Jaguar iPace MY20 auxiliary battery replacement at much cheaper price than getting a garage to do so

On: 9 May 2025

Best price & rapid shipping

Bought for my 2015 Evoque SD4 which was giving battery warnings on nearly every entry and sporadic services. Firstly, easy to find right part as the registration look up worked fine (its been failing on 50% of sites, including AA and RAC due to previously having a private plate). Price was easily the best price, even compared to other battery specialist sites. Shipping was so fast I had to delay the courier due to being away with work when dispatched. Easily done.
Finally, all warnings cleared and full functionality cleared. Stop-start sprang into life having never worked at all and started to doubt my model had it. 2 weeks in and no issues.

Jaguar's stop/start battery

Our service agent had quoted several hundred pounds to replace the Jaguar's stop/start battery. I ordered this Exide battery, received it in a day and replaced the old battery in 20 minutes, saving a huge amount! Of course it has worked perfectly - the original battery had Exide markings too and appeared to be identical!

The most important questions about high-quality replacment batteries for cars

Find the right battery here

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.
