Delipow DLP-513 4-Bay Smart Battery Charger | Auto LED Cut-Off for 1.5V AA/AAA Li-ion Batteries
Description
Product Description
The Delipow DLP-513 is a dedicated 4-bay smart battery charger designed specifically for 1.5V AA and AAA lithium-ion rechargeable batteries. It features a standard USB input (DC 5V), delivering a stable 300mA charging current per slot for all 4 slots. Equipped with an intelligent microcomputer chip, it provides a precise 1.45V±0.05V cut-off voltage and a ≤100mA cut-off current. Once the battery reaches full capacity, the charger automatically stops the charging process, preventing overcharging and significantly extending battery lifespan. The intuitive LED indicator system features a red-to-green auto cut-off (Red for active charging, Green for fully charged), giving you a clear visual cue that your batteries are ready for use. The 4 independent channels allow you to charge 1 to 4 batteries safely and efficiently without interference.
