Do you have a question? Hopefully you'll find the answer in our comprehensive FAQ covering those questions we're asked the most. If you can't find the answer you're looking for below just get in touch and we'll be more than happy to help.

Q. Which battery do I need for my car?

A. There are around 20 distinct sizes of UK car battery with each having distinct features such as dimensions, terminal types and Ah. There is a wealth of fitment guides available which try to guide you to the correct battery for your car, but these can be notoriously inaccurate and we do not recommend relying on these. The correct method of determining your battery is to look at your existing battery, noting down the following: Ah figure (if shown), dimensions (in mm), positive terminal position and terminal type. Compare the gathered figures to the full list of our batteries you should find a match.

Q. Will my battery arrive ready to fit?

A. Yes! All our products arrive filled with acid, fully charged and ready to go. If you need any help regarding fitting your battery just contact us.

Q. On my battery there is a label stating ‘Please remove the bungs’. What does this mean?

A. These are the small red bungs on the side of the battery. They are inserted in to the battery for dispatch / transport purposes only and need to be permanently removed before the battery is to be charged or used. Please remove these bungs immediately on receipt of the battery, do not leave them in the battery even if battery is not being used for a period of time.

Q. Will I lose data and radio codes when changing my battery?

A. All vehicles are different. Most batteries can be changed without any loss of data or radio codes however we strongly suggest checking your vehicle hand book for advice.

Q. Can I store my battery rather than fitting it straight away?

A. You can, however you need to read the following to ensure your battery remains in top performing condition for when you do want to use it.

Q. Should I keep my battery on charge when in storage?

A. Keeping your battery on charge is always beneficial as batteries work using chemical reactions. As the battery discharges, it begins to sulphate and so may lead to the chemical reaction inside the battery being affected; therefore this will affect the performance of the battery. The battery charger would need to be fully automatic with a maintenance program.

Remember that if your battery fails due to sulphation it will not be covered under warranty. This kind of failure is classed as damage caused by the user through neglect.

Never overcharge your battery. Although you must always keep your battery as charged as possible when not in use, you must never overcharge it. Overcharging will cause the battery to heat up and its electrolyte will start to evaporate. In turn this will cause the battery's plates to break down, severely reducing the battery's ability to yield power. This type of damage is also not covered under warranty, as the battery is clearly not at fault.

Avoid deep discharging when possible. All batteries will deteriorate over time, and will eventually have to be replaced. Every time you use your battery then recharge it, its performance is ever so slightly decreased. This cannot be avoided.
