Lithium battery is a rechargeable battery, and its chemical reaction produces electric energy; Alkaline battery is a kind of dry battery, and once the chemical reaction inside it is over, it can't generate electricity, so it needs to be replaced. The use time and frequency are relatively low, so alkaline batteries can be selected. Therefore, the same three-volt electrical appliances can be used for lithium batteries, but not for alkaline batteries, because the performance and use of the two battery types are different.

In addition, lithium batteries have higher voltage, larger capacity and longer cycle life, while alkaline batteries are relatively low. Therefore, in the use of electrical appliances, if electrical appliances need high voltage, long-term or multiple use, it is recommended to use lithium batteries.
