The **Fenix ARB-L21-5000 21700 Li-ion battery** has a capacity of 5000 mAh. The battery has enough power and offers stable performances. It is also two times as powerful as a regular 18650/ 2300 mAh battery. But, please note: a 21700 battery does not replace the 18650 battery. This ARB-L21-5000 battery can only be used in various flashlights that were specifically designed for this type.


The battery is protected from overcharging and overheating.


## Tip when using the Fenix ARB-L21-5000


Some people say: 'I take great care of my batteries, I hardly charge them!' In case of Lithium Iion batteries this is not a good thing. These batteries will last a whole lot longer if you charge them on a regular basis.


Also add a [Fenix ARE-A2 battery charger](/en/pt/-fenix-are-a2-battery-charger.htm) or a [Fenix ARE-D1 battery charger](/en/pt/-fenix-are-d1-battery-charger.htm) to your order to charge the 21700 battery.

Snelle levering van de bestelling. Levensduur van deze batterij is enorm goed, hier kan je dus zeker op rekenen als het nodig is.

Een reserve li-on accu voor de Fenix TK16V2.0 en de E35R

Ce n’est pas ma première. Au top comme d’habitude chez Fenix, tant sur la puissance que sur l’autonomie et la longévité. 
J’en ai une depuis plus de 2 ans qui n’a pas bougé. 
Pratique lorsqu’on a qu’une seule lampe et qu’on ne veut pas s’encombrer d’un chargeur, même si les chargeurs sont vraiment très bons aujourd’hui. 
On a tous un câble USB-C qui traîne dans un tiroir. Permets également de la mettre rapidement sur un allume-cigare par exemple. 
Bref, très bon produit, très pratique de part justement cet atout de la prise USB-C pour la recharge, et donc très polyvalent. 
Je recommande à 200%

Prima batterij voor een schitterend licht!
