Here are the permissible temperature limits for charging commonly used lead acid batteries: – Flooded Lead Acid Batteries: – Charging Temperature Range: 0°C to 50°C (32°F to 122°F) – AGM (Absorbent Glass Mat) Batteries: – Charging Temperature Range: -20°C to 50°C (-4°F to 122°F) – Gel Batteries:
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.
The lead acid battery works well at cold temperatures and is superior to lithium-ion when operating in sub-zero conditions. Lead acid batteries can be divided into two main classes: vented lead acid batteries (spillable) and valve regulated lead acid (VRLA) batteries (sealed or non-spillable). 2. Vented Lead Acid Batteries
Reduced Capacity: Cold temperatures can cause lead acid batteries to experience a decrease in their capacity. This means that the battery may not be able to hold as much charge as it would in optimal conditions. As a result, the battery’s runtime may be significantly reduced. 2.
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.
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.
