Customer ServiceHow can I test the health of my lead-acid battery? Testing your battery''s health is crucial for identifying potential issues: Voltage Test: Use a multimeter to measure the resting voltage.A healthy battery should read around 12.6 to 12.8 volts. Hydrometer Test: For flooded batteries, a hydrometer can measure specific gravity, indicating charge levels.
Customer ServiceIf your lead acid battery fails the health test, it is an indication that the battery may need maintenance or replacement. Depending on the specific issue, you may consider actions such as cleaning battery terminals, replenishing electrolyte, equalizing charge, or replacing the battery if it is beyond salvageable condition.
Customer ServiceThe easiest way is simply to ask the manufacturer. Battery capacities are measured in amp hours (Ah) and Exide quote 90 Ah for one of theirs, Century quote 90 Ah for one and 85 Ah for another and Challenge quote 90 Ah for theirs so yours is likely to be similar - find out the manufacturer and get the data sheet for full details of capacity and how it''s affected by

1. Objective Methods other than capacity tests are increasingly used to assess the state of charge or capacity of stationary lead-acid batteries. Such methods are based on one of the following methods: impedance (AC resistance), admittance (AC conductance).
A snapshot taken with a CCA tester on a starter battery refers to the resistive battery condition only. Better electrolytes and corrosion-resistant electrode materials are keeping the resistance on modern batteries low through most of their life.
Unlike voltage, current and ohmic measurements, no universal instrument exists that can read the capacity of every battery that comes along. There are three common testing concepts: Scalar, vector and EIS with complex modeling (Spectro™). Scalar is the simplest of the three.
