Quick Answer
Gel battery swelling or bulging can be identified by checking for physical changes such as a rounded or domed shape, a bulge or protrusion on the surface, excessive swelling, or a significant increase in the battery's dimensions.
Signs of Swelling
Gel battery swelling can manifest in various ways. Look for a rounded or domed shape, which is often the first visible sign of swelling. This is usually a symptom of internal pressure buildup. In severe cases, the battery will display a significant bulge or protrusion on the surface, which can be as much as 1-2 inches in diameter.
Identifying Swelling Stages
To identify swelling at an early stage, inspect the battery for excessive swelling. A swollen gel battery will typically show signs of increased thickness, around 1/4 inch (6 mm) or more. In addition, the swell may feel soft or mushy, indicating a significant internal pressure buildup. Be aware that these changes can be slow and may not be immediately noticeable.
Visual Inspection Techniques
A thorough visual inspection is crucial in identifying gel battery swelling. Check the battery’s surface for any irregularities, cracks, or open seams, which can be a sign of internal pressure buildup. Also, inspect the battery’s terminals and cables for signs of overheating or damage. Compare the battery’s dimensions and shape to its original specifications, noting any significant changes. If you suspect swelling, consult the manufacturer’s recommendations for proper handling and disposal.
