    Long lasting.

    Purchased this as a back up battery for my Wuben X4 flashlight. Great bit of kit. I use the torch daily but admittedly not for huge amounts of time. Charged it once when I got it and only just showing half charge after about 3 weeks. Recommended.

    Nitecore 18650 4000MAH 10A Battery

    Posted by brett almond on 24th Feb 2025

    Bought this to use in a Pard 007, and what a difference it has made to a nights shooting, pretty quick to charge as well. Only used it twice which is why I didn't score higher than a 4, but it is in a different league to the battery that came supplied to the unit, I will be looking to buy another soon. Service as always was spot on getting it delivered next day well wrapped, but overly wrapped.
