RS Taichi heated gloves. Includes a charger and 4 extra batteries. I bought these new and used them only once, with inner gloves. It's been 2-3 years since I bought them, so I'm not sure how much the batteries have deteriorated, but I've occasionally charged and discharged them even when not in use. Please consider them as a bonus. The charger connector has slightly worse contact than when I bought it, but it still charges. ◾️RS TAICHI e-HEAT Heated Gloves RST639 ◾️4 Batteries & Charger Included as a Bonus Thank you.
