Rechargeable batteries have their benefits, but for their convenience, reliability and minimal maintenance, non rechargeable batteries continue to be preferred in household purposes and low power devices. For single use, these batteries come in several types, including alkaline, lithium and zinc carbon. There is truly no one size fits all; several types exist, and each serves a particular purpose, has its own benefits and liabilities. An example is that lithium based non rechargeable batteries exhibit high energy density and therefore when we need long lasting especially for the sake of medical devices or smoke detectors, lithium based non rechargeable batteries are chosen. However, their environmental downsides and their usage in applications that can really take advantage of their strengths should be considered.

Non rechargeable batteries are instant ‘power instantly’ for things like emergency kits, remote controls and portable electronics, while rechargeable batteries for rechargeable kits. The recent developments in battery technology make decisions between non rechargeable options such as lithium-ion (Li-ion) and lithium-polymer (Li-Po) batteries quite complicated to make. By understanding the differences between “li on li po” options or “lithium ion v lithium polymer” type of batteries users can learn to make better and more sustainable choices dependent on their energy needs and the safety requirements.
