Our Story

Over a Decade of Lithium Battery R&D

Since 2009, JOOY-TASK has served the demanding Karaoke (KTV) microphone battery market, where devices are used intensively every single day — one month of KTV usage is equivalent to more than a year of typical household use.

In 2014, we invested in R&D and launched an independent 1.5V lithium battery development project, purpose-built for high-frequency professional use. Over more than ten years of continuous refinement, we advanced from basic designs to self-developed exclusive chips, from simple structures to optimized safety-first engineering, and from low-capacity trial products to high-capacity, mass-produced best sellers.

Every product is validated through long-term, real-world testing across thousands of KTV venues nationwide before it ever reaches a customer. As our lithium-ion battery lineup expanded — from 1.5V USB-C rechargeable AA/AAA batteries to 3.7V 18650 cells, D-type and custom sizes — we broadened into mid- to high-end sectors including smart locks, wireless microphones, mice and keyboards, game controllers, headlamps and outdoor lighting.

In 2026, we established a dedicated import-export division to serve overseas distributors, wholesalers and OEM partners directly from our factory.
