Coast ZX Rechargeable AA Batteries - 4-Pack Save money and reduce waste by switching to rechargeable batteries. These AA and AAA batteries from Coast turn any device into a rechargeable one, as they’re optimised to work safely and reliably in devices that were designed for standard alkaline batteries, with a long run time. They’re also able to be recharged, up to 1,000 times, individually (as opposed to having to charge a complete set at a time) using the supplied USB lead. Charging takes only 2.5hrs for the AA size and 1.25hrs for the AAA size. |
