Fenix ​​18650 Battery 3.5 Ah (USB)

Designed for long sessions without charging. This 18650 Li-ion battery has a high capacity, allowing powerful lights to last longer on a single charge. Especially during ultra-trails, night hikes, or camping trips, you won't need to switch batteries as often.

Charging without a separate battery charger. You can charge the battery directly via the built-in micro-USB port using a cable, power bank, or adapter. This is convenient on the go or during trips where you want to carry as few extra accessories as possible.

Consistent performance during intensive use. The battery maintains stable performance when a light runs at higher brightness levels for extended periods. You will particularly notice the benefit of reliable light output on technical trails or dark descents when concentration and visibility become crucial.

Check in advance whether your lamp is suitable for protected button-top 18650 batteries. Not every model supports this version.
