Due to shipping regulations this battery can only be shipped to the Mainland UK, unless it is sent with a compatible torch or battery charger. Any orders to outside of the Mainland UK (including NI, Scottish Highlands, Channel Islands etc.) for this battery without compatible equipment will be cancelled.

The Fenix ARB-L21-5000U is a premium quality high capacity 21700, 5000 mAh lithium-ion battery specifically designed for high intensity torch use and is the perfect companion for for all Fenix 21700 powered lights.

As well as being able to charge in a battery charger (Fenix charger recommended) the ARB-L21-5000U has an additional feature that sets it apart from standard 18650 batteries as it has a built-in USB-C charging port in the top of the battery.

Using a USB-C charging cable this battery can be easily charged up which is not only convenient but can also save money on buying a separate charger. A charging indicator will glow red once the charging cable is plugged in and connected to power to show charging is in progress and it will turn blue once charging is complete.

Please note: This battery is larger than an 18650 battery and cannot be used in standard 18650 sized torches. Please check the dimensions of your intended application before purchasing, as they may not fit some products.

Non Mainland UK Delivery

You may see this option if your order partly or fully contains lithium batteries that are not contained within the item we are shipping. If your postcode is not part of the Mainland UK for postal purposes then we will determine the best way to send your item(s) and in some cases we may have to cancel the order or offer an alternative solution, this is because Royal Mail and couriers have strict rules regarding the transport of lithium batteries and in the case of couriers certain regions of the UK have increased shipping costs.
