Let's first see the difference between Lithium and lithium-ion Here is a simple definition to better understand the difference, Lithium batteries are primary cell batteries, meaning you can recharge them if they are empty, while Lithium-ion batteries are secondary cells, meaning you can recharge them and use them many times as they still operate well. Another way if you are still confused, Packaging; take a quick look at the packaging of your item and it will indicate if it is a lithium battery or not. If you can access the battery the manufacturer will put all the necessary info on it, in addition of proper use and actions for your safety.
