AmazonBasics AA 1.5 Volt Performance Alkaline Battery. Made with high-quality components, the AmazonBasics battery provides safe operation for both the user and the device. If misused or over-worked, the battery’s insulating ring—a short circuit preventive washer (SPW)—protects against short circuiting and self discharging, while two small holes prevent heat build-up and bursting.
