Description
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. These batteries have a built-in protection and as such, are longer than 65mm - please check the tech spec for dimensions.
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.
