What type of battery suits your needs best? We define ‘type’ in several ways when customers ask us. And usually discuss whether they are rechargeable, the chemicals they use, and their battery applications. We often begin by separating primary from secondary batteries.
Comparing Primary Versus Secondary Batteries
Primary, Single Use Batteries We Use Once
We recommend you only use primary batteries once. They are single use and cannot be recharged safely. Once their stored chemical energy is used up, we must replace them.
Common examples include alkaline batteries, zinc-carbon batteries, and lithium coin cells. They are ideal for remote controls, clocks, flashlights, smoke detectors, and watches. This is because they have a long shelf life and are convenient.
Rechargeable Batteries We Re-Use Many Times
We can charge and discharge secondary batteries many times. This type of battery allows reversible chemical reactions, so we can store fresh electrical energy after we use them.
Popular rechargeable battery types include nickel-metal hydride, lithium-ion, and lead-acid batteries in cars, and backup power systems. Lithium-ion batteries power smartphones, laptops, tablets, power tools, and electric vehicles. They offer high energy density and relatively low weight.
Classifying Type of Battery By Chemical Composition
Another way we can classify batteries is by their chemical composition. Alkaline batteries use zinc and manganese dioxide. Lithium-ion batteries rely on lithium compounds to store energy. Lead-acid batteries have lead plates and sulfuric acid, making them more robust but heavier.
Each chemistry offers different advantages in terms of cost, lifespan, safety, energy storage, and environmental impact.
Choosing The Battery Type That Suits You Best
We tell our customers that choosing the right battery depends on their application. Disposable batteries suit low-power devices that they use occasionally, whereas rechargeable batteries are more affordable and environmentally friendly for frequently-used electronics.
As battery technology continues to improve, newer designs are becoming safer, more efficient, and capable of storing greater amounts of energy. Our world of batteries truly supports everything from portable electronics, to renewable energy storage, to electric transportation.
