If the float voltage is set to 2.30V/cell at 25°C (77°F), the voltage should read 2.27V/cell at 35°C (95°F). Going colder, the voltage should be 2.33V/cell at 15°C (59°F). These 10°C adjustments represent 30mV change. Table 3 indicates the optimal peak voltage at various temperatures when charging lead acid batteries.
Temperature plays a crucial role in the performance and longevity of lead-acid batteries, influencing key factors such as charging efficiency, discharge capacity, and overall reliability. Understanding how temperature affects lead-acid batteries is essential for optimizing their usage in various applications, from automotive to industrial settings.
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.
Only at very high ambient air humidity (above 70%), water from outside the battery can be absorbed by the hygroscopic sulfuric acid. In summary, the internal temperature of any lead-acid battery (flooded and AGM) should not exceed 60 °C for extended time periods frequently to limit vaporization. 2.1. External and internal heating of the battery
Heat is the worst enemy of batteries, including lead acid. Adding temperature compensation on a lead acid charger to adjust for temperature variations is said to prolong battery life by up to 15 percent. The recommended compensation is a 3mV drop per cell for every degree Celsius rise in temperature.
Some lithium-based packs are momentarily heated to high temperatures. This applies to batteries in surgical tools that are sterilized at 137°C (280°F) for up to 20 minutes as part of autoclaving. Oil and gas drilling as part of fracking also exposes the battery to high temperatures.
