Mapping the Capacity–Conductance Boundary in VRLA Lead-Acid Batteries

This article distills a technical study into a practical, plain-English guide on how **electrolyte conductance** and **deliverable capacity** relate inside **VRLA (valve-regulated lead-acid)** batteries. By modeling the **electrolyte** (acid + water) and the **plates** (active materials) separately—and then combining their constraints—we obtain **upper and lower bounds** that define where a battery’s **normalized conductance** \(G_d/G_n\) and **normalized capacity** \(Ah_d/Ah_n\) can realistically sit. The result helps field engineers interpret conductance readings, separate **undercharge/sulfation** from **electrolyte dry-out**, and decide when capacity testing or replacement is justified.

Battery Health Testing with Impedance & Conductance: A Clear, Practical Guide

Impedance and conductance tests provide a fast, non-destructive way to assess battery health—especially for lead-acid and VRLA cells—without doing a full discharge test. This article explains what these tests measure, why baseline values matter more than one-off readings, and how to build a simple trending program that reliably flags aging cells before they fail.
