Lithium-Ion Batteries Vs Lead-Acid Batteries

Summary: Since batteries play a crucial role in powering up the tools people use, it is important to consider one’s options to determine which kind is best for the job.


In a world where many people rely on technology to carry out their day-to-day tasks, consumers need a reliable method of powering up the vehicles, tools, and devices they use on a regular basis. Lead-acid batteries were invented in 1859 and are the oldest form of rechargeable batteries. The familiar lead-acid battery has been used for several decades, reliably powering up such things as submarines and lights.


Some have wondered whether it is worth switching from the reliable lead-acid battery to the newer lithium-ion battery. Below are some reasons why this new battery may be worth the upgrade.


Voltage Levels


Lithium-ion batteries are able to maintain constant voltage levels throughout the entire discharge process, yet one will notice that lead-acid batteries tend to drop in voltage levels as the battery is drained. This constant drop in voltage levels actually make lead-acid batteries less reliable and less efficient to use. Reliability is key, which is why lithium ground support equipment may be better for starting an engine than the lead-acid counterpart.




Lead-acid batteries might have lower upfront costs than lithium-ion batteries, but there is more to the story. If one examines long-term expenses, the better performance and reliability of lithium-ion batteries actually make them less expensive than lead-acid batteries. Lithium-ion batteries, whether purchased from Start Pac or another power manufacturer, do not need to be replaced as often.




Depending on one’s situation, one may have to move their battery around with them from place to place. Lead-acid batteries can be more than double the weight of lithium-ion batteries, ultimately making them tougher to travel with. In aircrafts, for example, weight limits are very important, suggesting that lead batteries limit what one can bring with them on-board.
