TESLA CR123A lithium dioxide batteries are designed to provide reliable, long-lasting power for specialized devices. These cylindrical batteries are commonly used in small electronic devices. Due to their lightweight materials, TESLA CR123A batteries are ideal for small cameras and portable lighting systems. They are also very convenient for powering flashlights that require instant power. They contain manganese dioxide, a chemically very stable substance. They have a storage warranty of up to 7 years (if stored properly), so you can be sure they'll be ready when you need them. For safety, they're designed with a child-resistant lock. Leakage protection also minimizes the risk of hazards and ensures safe use.
