Hydrometer Test: For flooded batteries, a hydrometer can measure specific gravity, indicating charge levels. Load Test: Apply a load to see how well the battery holds voltage under stress. What are the common maintenance practices for lead-acid batteries?
Here is a 15-step process to begin every lead-acid battery maintenance process with an important and effective visual battery inspection. Check that battery model and cell/unit manufacturing data code are visible and cell numbering is adequate and correct. 2. Look for dust, corrosion, water or electrolyte
If the voltage reading is lower than the manufacturer’s specifications, the battery may be weak and need to be replaced. If the voltage reading is within the manufacturer’s specifications, the battery is likely in good condition. To get a more accurate reading of a lead-acid battery’s health, you can use a hydrometer.
In the case of a lead-antimony battery, measure and record the specific gravity of 10% of the cells and float charging current. For chemistries other than lead-antimony and where float current is not used to monitor the state of charge, measure and record the specific gravity 10% or more of the battery cells.
A fully charged lead-acid battery should have a voltage of around 12.8 volts. If the voltage drops below 12.4 volts, the battery needs to be recharged. Internal resistance is also an important factor to consider. A battery with high internal resistance will have difficulty delivering power, which can result in poor performance.
Field experience has shown that the electrolyte analysis type battery testing is currently not sufficiently accurate, consistent or reliable to be satisfactory for Fire Alarm battery capacity verification. Inadequate and / or inconsistent test methods are likely to result in variable results.
