Customers find these batteries offer great value for money and work as well as name-brand competitors, with one customer noting they perform particularly well in LED diodes. They come in large multi-packs and are particularly useful for tea lights and classroom STEM projects. The battery life and quality receive mixed reviews - while some say they last longer than regular batteries, others report they don't last long at all, and while some find them excellent, others consider them among the worst they've tried. Reliability is also mixed, with some customers reporting no problems while others find them unreliable.
