- The Hoco JA4 AAA rechargeable lithium batteries are designed for speed, requiring only 40 minutes to achieve a full recharge.

- The Hoco JA4 batteries are engineered to match the standard AAA physical dimensions of 10.1 × 44.5 mm. They are fully compatible with common small electronic gadgets that utilize AAA cells, such as wireless mice, keyboards, portable fans, radios, and battery-operated toys. Their 3.7V output provides stable power, making them a direct, high-performance substitute for traditional alkaline or NiMH rechargeable batteries.
