The Nitecore NL1840HP 18650 4000mAh Li-ion battery is a high performance, protected cell. The rechargeable battery has a continuous discharge up to 10A, making it suitable for high drain devices, such as 18650-powered flashlights.

The battery has several internal safety features, including a pressure relief valve protection and a built-in intelligent protective circuit which protects against overcharge, over discharge and short-circuitting. Externally, the battery is equipped with nickel-plated stainless steel protectors and coated with a durable metallic film to guard against abrasion.

Please note: We are unable to accept returned batteries once they have been opened, so please ensure they are the correct cell for your device before ordering.

Due to shipping restrictions we are unable to send orders containing only batteries without a device to Northern Ireland and the Channel Islands. Orders that include a device such as a torch and/or charger are unaffected.
