In today's world, toys and batteries are happily married. Almost one in five toys at home is battery-operated. Toys help children develop their imagination. They help improve children’s dexterity and language skills. Some devices need a long-lasting, low-power steady flow of energy: think remote controls, game controllers and keyboards. However, robot toys, toy computers, musical toys, and other high-drain devices need a more powerful supply of energy.

Which types of batteries are suitable for kids' toys?
Remote control—Alkaline battery AA/AAA
Game controllers—Alkaline battery 23A 12V / Lithium battery AA
Keyboards—Alkaline Battery AA/AAA
Musical toys—Lithium Battery AA

What's the difference between lithium and alkaline batteries?
Alkaline batteries are platinum partners for everyday electronic devices and last longer than carbon zinc batteries. Lithium batteries have several distinct advantages over their alkaline counterparts:
* They're designed to last longer, making them a good choice for high-tech and smart devices, and those electronics for which changing the battery is inconvenient.
For example, automated utility meters, oceanographic instruments, etc.
* They can withstand extremely low temperatures. Lithium can operate without failing in a very cold climate, so it's ideal for outdoor applications.
Temperature range: alkaline battery from 0℃ to 40℃, lithium battery from -40℃ to 70℃.
* Lithium batteries are lighter than alkaline batteries, so they offer an advantage when used with portable devices, especially cordless power tools.
Wireless devices: Ceiling Fan Control, Dimmer, Soldering Iron, etc.

In short, a lithium battery can be used as a high-performing alternative to a standard alkaline battery. However, the benefits come at a cost: Lithium is a more expensive technology, which means a higher price point. Don't forget to read the manual before using electric appliances.

P.S. Lithium batteries are restricted as carry-on travel items by some airlines.
