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.

Suite à ma demande de retour car produit non conforme, je n’ai jamais eu de réponse à ma demande. Très décevant. Je ne recommande pas.

Très bonne batterie. Placée dans une lampe Fenix TK20 UE, donne une très bonne autonomie.

Ik kwam met een defecte zaklamp (dacht ik)
Batterij bleek na controle defect te zijn ,  
Onder het genot van een bak koffie en een gezellig gesprek werd het opgelost en liep ik als tevreden klant (weer) naar de uitgang. 
Goede service en verstand van zaken 👍🏻 ga zo door

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

General information

We always weigh a product as bare as possible. Knives and axes always without their sheath, lights (if possible) without their battery. For knife sets we measure the entire weight. This may deviate from the manufacturer's specifications.
