Gaming keyboards tend to use RF wireless with a USB dongle, instead of a Bluetooth connection, which is more popular with modern "standard" wireless keyboards. That's because it allows manufacturers to use a more reliable direct connection, with a higher polling rate — that means the connection between the board and your computer refreshes itself much more often, minimizing input lag. Some advanced models still include Bluetooth, along with fancier options like pairing multiple devices to the same USB dongle. Range typically isn't a concern if you're using a keyboard with a gaming desktop, but you might want to think about it if you have a gaming PC hooked up to your TV.

Most high-end wireless gaming keyboards can also use a direct wired USB connection, if you're worried about wireless interference in a crowded environment.

Unlike gaming mice, battery life generally isn't a big concern with gaming keyboards. They're big enough that there's plenty of space for internal batteries that last for weeks, or even months, between charges. That is, unless you over-use that fancy RGB lighting with dazzling animation...in which case, it might last just a few days or hours. It's best to turn off the lights if you don't know when you'll get your next charge. If it's available, check the milliamp-hour (mAh) rating for the battery.
