Meet ZITHION-X®, our AA and AAA lithium rechargeable batteries. Our patent-pending technology mimics the voltage of alkaline batteries, so they work in just about any device that takes AA or AAA batteries, even ones where other rechargeables fall short.


Many NiMH and lithium rechargeable batteries aren't fully compatible with devices built for alkalines because they run at a different voltage. Conventional lithium batteries also deliver a constant voltage, which can lead to poor runtime, sudden power drop-offs and even damage. ZITHION-X® solves that, so you get reliable power across the widest range of everyday and high-performance devices.
"We had been designing rechargeable batteries for our lighting products for over 14 years. Then, one day we realized what a great solution this could be for a wide range of consumers in all products, not just our lights," said Tyler Peterson, fourth-generation President at COAST.
ZITHION-X® batteries charge fast and can run two to six times longer than standard rechargeable lithium and NiMH batteries. A built-in safety circuit prevents overheating, they're corrosion resistant and each one is good for more than 1,000 charges, so they quickly become more economical and sustainable than single-use batteries.
Each battery has its own USB-C port, and a 4-way split charging cable is included. No clunky charging docks or special cords, just plug in and go.
