The COAST ZITHION-X AA Rechargeable Battery 4-Pack provides a reusable power option for flashlights, headlamps, remotes, cameras, gaming equipment, test instruments and other devices designed to operate with AA alkaline batteries. Each lithium-ion cell delivers a regulated 1.5-volt output with a 2400mAh capacity and 3Wh energy rating. COAST ZX Optimized Voltage circuitry is engineered to produce a power curve similar to a conventional alkaline battery, helping the cells work across a broad range of everyday electronics while maintaining the output those devices expect. An integrated USB-C port on every battery eliminates the need for a separate charging cradle. The included four-way charging cable connects to all four cells at once and offers USB-C and USB-A power-input options, making the set convenient to recharge from compatible wall adapters, power banks and other USB power sources. A complete charge takes approximately 2.5 hours under appropriate charging conditions. Individual charge-level indicators make it easier to monitor charging progress, while built-in overcharge and discharge protection circuits help manage each cell during use and recharging. The batteries also use a leak-resistant casing intended to help protect equipment from corrosion associated with leaking disposable cells. Each ZITHION-X battery can be recharged up to 1,000 times, reducing the need to continually replace single-use AA batteries. This exact set contains four rechargeable AA cells, the four-way charging cable and a storage case that keeps the batteries organized between uses. It is a practical portable-power choice for camping gear, household electronics, emergency supplies, work equipment and other frequently used AA-powered devices.Specifications and Features: Four rechargeable AA lithium-ion batteries 2400mAh capacity and 3Wh energy per battery 1.5V output for everyday AA alkaline-powered devices Integrated USB-C charging port on each battery Approximate charge time: 2.5 hours Built-in charge-level indicator Overcharge and discharge protection circuits Includes USB-C four-way charging cable with USB-A/USB-C input Includes battery storage case Series: ZITHION-X Product Type: Rechargeable AA Batteries Manufacturer Part Number: 31007 UPC: 015286310071
