Frequently Asked Questions

WHAT IS PAYPAL CREDIT?

PayPal Credit is like a credit card, without the plastic. It's a credit limit that sits alongside your PayPal account which you can use for your online purchases.

WHAT CREDIT OFFERS ARE AVAILABLE?

A 0% interest offer you can use again and again: PayPal Credit's 0% interest offer is better than just an introductory offer. Every time you spend £99 or more, you will automatically get 0% interest for 4 months on that purchase.

Plus, you can spread the cost of purchases under £99 at the standard variable rate of interest, currently 23.9% p.a.

*The minimum payment due still applies to 0% offer balances. Any remaining balance due after the 4-month promotional period or any transactions under £99 will be charged interest at 23.9% p.a. (variable). In order to maintain the 0% offer, you need to keep up monthly repayments and stay within your credit limit.

HOW DO I APPLY?

Applying for PayPal Credit is easy. Just click on the PayPal Credit button on our checkout page.

The application form takes minutes to complete. PayPal will then run a credit check and, if approved, you'll have a credit limit linked to your PayPal account as soon as you accept your Credit Agreement.

You can use the credit limit granted to pay for today's purchase and future purchases at thousands of online stores where PayPal is accepted, up to your credit limit.

DO I NEED TO RE-APPLY IF I ALREADY HAVE PAYPAL CREDIT?

If you already have PayPal Credit you do not need to reapply, just select PayPal Credit as your payment option at checkout.

DO I NEED TO HAVE A PAYPAL ACCOUNT?

Yes, however if you don't have a PayPal account, you can create one as part of the PayPal Credit application.

WHAT DO I DO IF I AM UNSUCCESSFUL IN APPLYING FOR PAYPAL CREDIT?

If you have been declined for PayPal Credit, PayPal will send you more information about why your application was unsuccessful. You can still use PayPal to complete your purchase.

WHAT HAPPENS IF I WANT TO RETURN THE ITEM I BOUGHT USING MY PAYPAL CREDIT?

  • Representative 23.9% APR (variable)

The Ryobi RB1840X ONE+ 4.0Ah 18V Lithium+ Battery from ITS is a compact yet high-performing power source designed to deliver longer runtime, improved durability and consistent output across the entire Ryobi ONE+ system.

Positioned as a versatile mid-capacity option, it strikes an ideal balance between weight and performance, making it suitable for both DIY users and tradespeople who need dependable power without the bulk of larger batteries.

At the core of this battery is Ryobi’s Lithium+ technology, which provides increased power, longer runtimes and enhanced durability compared to earlier lithium battery generations. This ensures tools maintain strong, consistent performance across a wide range of applications, from drilling and cutting to garden maintenance and general DIY tasks.

The 4.0Ah capacity offers a noticeable step up in runtime compared to smaller batteries, allowing users to complete more work on a single charge while still benefiting from a compact and lightweight design. This makes it particularly well suited for users who want extended use without the added weight of higher-capacity packs.

A key feature is Ryobi’s IntelliCell technology, which monitors and balances each individual cell within the battery. This intelligent system helps maximise runtime, improve safety and extend overall battery lifespan by ensuring optimal performance across all cells.

User convenience is enhanced with a built-in 4-stage fuel gauge, providing a quick and clear indication of remaining charge levels at 100%, 75%, 50% and 25%. This allows users to plan work more effectively and avoid unexpected downtime during tasks.

Durability is another strong point, with a tough pack design and integrated impact protection that helps safeguard the battery against knocks and drops on site. This robust construction ensures long-term reliability, even in demanding working environments.

As part of the Ryobi ONE+ platform, this battery is compatible with cordless tools across home, garden and automotive applications. This system-wide compatibility makes it a cost-effective and flexible solution for users looking to expand their tool collection without investing in multiple battery platforms.
