Consider the type of batteries your flashlight uses and how long they last. Some flashlights are rechargeable, while others use disposable batteries.
Lithium batteries are always rechargeable models. Lithium batteries offer more life compared to alkaline batteries.
While lithium and alkaline batteries differ significantly in terms of performance, each has its unique strengths and weaknesses. The upfront cost of a lithium battery can be up to three times more than an equivalent alkaline battery, making alkaline far more affordable.
One important thing to remember is that lithium batteries don't need to be replaced as often as alkaline types. Because of this, a lithium battery will offer a better return on investment, saving you money in the long run.
