Used in cameras, hearing aids, transmitters, medical equipment, pocket calculators and watches, disposable lithium batteries offer long lifespan for items in regular use. Small or slim devices often use coin cells, which we sell in many sizes. Larger lithium batteries such as the CR2, CR123 or 9V are common in cameras and smoke alarms. Why not benefit from Lyco’s attractive prices and stock up on batteries now? If you need power urgently, we offer next-day delivery with a generous 8PM ordering deadline.
