Product details:
➤Our AA AAA battery charger features four separate charging slots that work independently, allowing you to charge any number of rechargeable AA and AAA batteries simultaneously without needing to pair them. This flexibility offers maximum convenience.
➤Our rechargeable battery charger features intuitive LED indicators. It displays a red light while charging and switches to green once the batteries are fully charged. If you observe alternating flashing between red and green lights, it indicates detection of issues like low voltage, short circuits, or battery damage, ensuring the safety of your batteries.
➤Our 4-bay battery charger employs a constant voltage charging method that minimizes charging-related losses, thus extending the lifespan of your batteries. Importantly, the charger automatically stops charging once the batteries reach full capacity, preventing overcharging and ensuring safety.
➤When powered on, the charger performs a self-test, signaled by alternating flashes of the traffic light indicator, ensuring its proper functioning. When inserting batteries, the charger intelligently detects defects, short circuits, or low-voltage issues, promptly halting charging to safeguard your batteries and device.
