4. Setup
4.1 First Use
For optimal performance, it is recommended to fully charge the batteries before their first use. The batteries included are pre-charged, but a full charge cycle is beneficial.
4.2 Connecting the Charger
The EBL 819 Charger offers two convenient ways to connect to a power source:
- Built-in USB Charging Cable: Connect the integrated USB-A cable directly to any standard USB power adapter (e.g., wall charger, computer USB port, power bank).
- Micro USB Input Port: Use a separate Micro USB cable (not included) to connect the charger to a 5V/2A power adapter. It is recommended to use a 2A adapter for optimal charging speed; do not use a 1.0A adapter.

6. Maintenance
6.1 Cleaning the Charger
Before cleaning, always unplug the charger from the power source and remove all batteries. Use a soft, dry cloth to wipe the surface of the charger. Do not use abrasive cleaners or solvents.
6.2 Battery Storage
Store batteries in a cool, dry place away from direct sunlight and extreme temperatures. For long-term storage, it is best to store Ni-MH batteries with a partial charge (around 50%).
6.3 Battery Lifespan and ProCyco Technology
EBL batteries feature ProCyco (Professional Recycle) technology, which helps maximize their power performance and extends their cycle life. These batteries are designed for low self-discharge, retaining a significant portion of their charge even after extended periods of non-use. For example, they are designed to maintain 80% of their capacity after 3 years of storage.
