These High quality and durable AA BTY batteries are just the ticket for high energy and long life in a battery. Nickel-Metal Hydride construction insures multiple recharging without loss over time. I myself have them in our solar outdoor lighting and get great service out of them before replacement is needed. Provides continuous power to your devices and are durable in low and high temperature operations (Think here in Arizona!) Great for cameras, watches, calculators LED Lights and other small electronic devices. Even though the battery states 3000 on the label they are a standard 2200 mA.
