What is the primary benefit of using lead-acid batteries in aviation?

The primary benefit of using lead-acid batteries in aviation centers around their reliability and cost-effectiveness. Lead-acid batteries are known for their long history of usage in various applications, including aviation. Their construction allows them to provide stable voltage and can deliver high current outputs needed during aircraft starting and other applications. This reliability is crucial in aviation, where safety and performance are paramount.

Moreover, lead-acid batteries tend to have a lower upfront cost compared to other types of batteries, such as lithium-ion. This makes them a more accessible option for many aviation applications, maintaining a balance between performance and financial considerations. Even though lead-acid batteries do have some drawbacks, such as weight and energy density compared to newer technologies, their proven track record in reliability and economical benefits solidify their use in the industry.
