Discharging lead acid batteries at extreme temperatures presents its own set of challenges. Both low and high temperatures can impact the voltage drop and the battery's capacity to deliver the required power. It is important to operate lead acid batteries within the recommended temperature ranges to maximize their performance and lifespan.
Lead-acid batteries perform well at 20°C (68°F) but can tolerate a wider range of 0°C to 40°C (32°F – 104°F). The National Renewable Energy Laboratory states that operating batteries outside their optimal temperature ranges can lead to reduced capacity and increased wear.
A lead acid battery charges at a constant current to a set voltage that is typically 2.40V/cell at ambient temperature. This voltage is governed by temperature and is set higher when cold and lower when warm. Figure 2 illustrates the recommended settings for most lead acid batteries.
It is important to operate lead acid batteries within the recommended temperature ranges to maximize their performance and lifespan. When it comes to cold weather conditions, alternative battery options like AGM (Absorbent Glass Mat) and LiFePO4 (Lithium Iron Phosphate) batteries perform better than traditional lead acid batteries.
Specifically, for every 15 degrees Fahrenheit above 77°F, battery life decreases by half. Maintaining batteries within the optimal temperature range is essential for better performance and longevity. The efficiency of a battery is also temperature-dependent. Optimal operation usually occurs between 20 to 25 degrees Celsius.
