Some users install plastic trays to protect batteries from concrete. While this practice might prevent physical damage, it does not significantly impact battery performance or lifespan. According to a 2023 report by the Energy Storage Association, using trays can offer slight insulation, reducing temperature fluctuations, but it is not a necessity for battery health on concrete.
Concrete Contributes to Battery Overheating:
The idea that concrete contributes to battery overheating is another myth. In fact, overheating in batteries can result from poor ventilation, high external temperatures, or excessive charging rates. The Concrete Institute (2023) asserts that concrete itself does not raise battery temperatures but can influence local conditions slightly, especially in extreme environments.
Battery Lifespan Decreases Due to Concrete:
Some users worry that prolonged exposure to concrete diminishes battery lifespan. However, battery lifespan is primarily influenced by charging practices, discharge rates, and maintenance. A review by Johnson & Associates (2022) highlights that lifespan is more affected by operational conditions than the immediate surface it rests on.

Understanding these myths can help users manage their lead acid batteries more effectively and avoid unnecessary precautions or concerns.

Can Concrete Actually Drain Charge from a Lead Acid Battery?

No, concrete does not actually drain charge from a lead acid battery. However, the moisture content in concrete can impact battery performance.

Concrete can retain moisture, which can lead to electrochemical reactions that may influence battery voltage. While concrete itself is not a conductor like metals, if it is damp, it can provide a pathway for ion exchange. This can result in parasitic current flow, which may discharge the battery over time. Therefore, placing a lead acid battery on wet concrete might affect its lifespan and performance. It is advisable to keep batteries on dry surfaces to ensure optimal operation.

Kingston (2018) found that a 10°C increase in temperature can double the reaction rate, leading to higher energy release.
Discharge Rates: High temperatures can also increase discharge rates, leading to faster depletion of battery energy. According to research published in the Journal of Power Sources by G. Yang (2020), batteries exposed to temperatures above 30°C can experience a significant drop in capacity, reducing the effective usage time.
Humidity Effects: Humidity impacts battery performance on concrete as well. High humidity levels can lead to condensation, which may cause short-circuiting in batteries. As noted in a study by L. J. Edwards (2021), batteries in humid environments exhibited a 15% decrease in efficiency due to moisture interference.
Lifespan Reduction: Prolonged exposure to extreme temperatures and high humidity can reduce battery lifespan. A correlation was found by F. Cho et al. (2019) showing that batteries in environments with both high temperature and humidity can lose up to 30% of their lifespan compared to those stored in optimal conditions.
Self-Discharge Rate: Temperature also influences the self-discharge rate of batteries. Higher temperatures increase this rate, leading to faster energy loss when the battery is not in use. Research by M. T. Yang and S. H. Park (2022) indicated that self-discharge can increase by 5-8% for every 10°C rise in temperature.

In summary, temperature and humidity play crucial roles in determining battery performance on concrete, impacting chemical reactions, discharge rates, efficiency, lifespan, and self-discharge rates.
