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 Nitecore NL2140 is a premium quality high capacity 21700, 4000 mAh lithium-ion battery specifically designed for high intensity torch use and is the perfect companion for the Nitecore New P12.

As with all Nitecore batteries safety is paramount and the NL2140 cell has a range of internal features to keep you, your devices and chargers as safe as possible. The 21700 battery has an innovative anode design with high temperature resistance, built-in PTC to inhibit high current surges, pressure relief valve which activates in the event of a rapid temperature increase and a microporous barrier that protects the delicate internal components. Externally, the cell is equipped with nickel-plated stainless steel protectors at both ends and is coated with a durable metallic film to guard against abrasion.

The 21700 is recommended to use with the following Nitecore chargers: UI1, UI2, UM2, UM4, UMS2 and UMS4.

Please note: This battery is larger than an 18650 battery and cannot be used in standard 18650 sized torches. To extend battery life it is recommended that it is charged every three months when unused for long periods.

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.
