In lead-acid batteries, internal resistive losses (Joule heating) occur with each cycle, converting energy to heat, lowering efficiency and capacity. Temperature affects lead-acid batteries similarly, with high temperatures increasing resistance and self-discharge, and low temperatures impacting performance .
general classes of lead-acid batteries: valve-regulated lead-acid batteries (VRLAB) and flooded cell batteries. The separator material used in VRLA batteries is absorbed glass mat (AGM).

State-of-health (SoH) of lead-acid battery is studied when no history data is available. Second-life batteries are focused on for this research. Electrochemical impedance spectroscopy is used for the analysis. Corrosion and sulphation are given a 20% and 80% share respectively for ageing of lead-acid battery.
Similar with other types of batteries, high temperature will degrade cycle lifespan and discharge efficiency of lead-acid batteries, and may even cause fire or explosion issues under extreme circumstances.
The most well-known method for this SoH evaluation is based on an estimation of the battery capacity and requires 20 h discharge at a controlled current which is far too long when checking just one battery at a street-corner battery shop.
Lead-acid batteries are highly sensitive to temperature. Testing should ideally be conducted at room temperature to ensure accurate results. Extremely high or low temperatures can skew the results of voltage, capacity, and resistance tests. To ensure optimal performance, it is recommended to perform battery testing at regular intervals.
Impedance Testing: Comprehensive Health Assessment Lead-acid batteries degrade over time due to several factors, including sulfation, temperature fluctuations, and improper maintenance. Testing these batteries at regular intervals allows us to detect potential problems early, ensuring longevity and optimal performance.
Batteries delivering above 80% are generally still in good condition, though they should be monitored for any decline. Capacity testing is one of the most reliable methods for evaluating the true health of a lead-acid battery. However, it can be time-consuming, as the battery must be fully discharged and then recharged. 3.
