Elfa is the official dealer of COAST Products in the Benelux. The company is a major player in the American lighting industry. Today, COAST offers the Zithion-X® AA, AAA, 9V and CR123 batteries. These USB-C rechargeable batteries provide superior performance for a wide range of everyday devices. Thanks to their fast charging time and long lifespan, Zithion-X® batteries are a practical and economical choice

COAST Zithion-X® rechargeable lithium batteries are a smart and powerful solution. They are perfect for anyone who expects more from their batteries.
COAST’s advanced AA, AAA, 9V CR123 rechargeable batteries combine long-lasting performance with ease of use. In addition, they provide a unique and constant voltage of 1.5 V (instead of 1.2 V), comparable to alkaline batteries.
Thanks to this voltage, Zithion-X® batteries are ideal for devices designed for alkaline batteries, including applications with high current output. This prevents devices with sensitive voltage requirements from shutting down unexpectedly.
The Zithion-X® AA battery has a capacity of 2400 mAh (3.0 Wh) and charges in approximately 2.5 hours. The AAA version has a capacity of 750 mAh (0.94 Wh) and charges in approximately 1.3 hours. Both provide a voltage of 1.5 V and use a USB-C connection with the included 4-way charging cable. The main differences are capacity, charging time, and size, which relate to the AA and AAA battery formats.
Zithion-X® batteries are rechargeable via USB-C and come with a practical multi-connector charging cable. This allows all batteries to be charged simultaneously via a USB-A or USB-C port. As a result, no separate charger is required: you can charge the batteries anytime and anywhere using a laptop, power bank, or adapter.
