Rechargeable Battery Ledlenser 21700 4800mAh (2 pcs) – for Ledlenser devices

Rechargeable 21700 lithium-ion battery pack from Ledlenser, supplied as a set of two cells with a nominal capacity of 4800mAh. These batteries are designed to serve as replacement or spare power sources for compatible Ledlenser flashlights and portable lighting. With 21700 format and nominal voltage in the 3.6–3.7V range, the pack offers extended runtime for activities where longer operation is required, including outdoor use, professional tasks, and emergency preparedness.

Advantages

These Ledlenser rechargeable batteries provide high-capacity energy storage in the larger 21700 form factor, enabling longer continuous operation compared with smaller cells. The cells are suitable for devices that require a stable nominal voltage around 3.6–3.7V and are manufactured to match the mechanical and electrical dimensions expected in compatible Ledlenser products. Supplied as a pair, they allow immediate replacement of depleted cells and convenient spares for field use or prolonged workloads.

Suitable for

• Ledlenser flashlights and portable lamps that accept 21700 batteries
• Outdoor activities such as hiking, camping, and fishing requiring extended light runtime
• Work and inspection tasks where reliable portable lighting is needed
• Emergency kits and preparedness packs for power redundancy

How to use

Before first use, ensure the device accepts 21700 cells with a nominal voltage in the 3.6–3.7V range and follow the flashlight manufacturer’s instructions for battery insertion. Insert each cell observing correct polarity and secure the battery compartment. Use a compatible charger designed for 21700 lithium-ion cells and charge according to the charger manufacturer’s guidelines. Replace both cells as recommended by the device manual or when performance indicates reduced runtime.

Usage recommendations

Store batteries in a cool, dry place away from direct heat and moisture. Use only chargers and devices specified for 21700 lithium-ion cells. Do not expose to high temperatures, open flames, or mechanical damage. For prolonged storage, keep cells partially charged according to lithium-ion storage best practices and check charge state periodically. Dispose of batteries through appropriate recycling channels.
