To determine if a battery is AGM (Absorbent Glass Mat), look for “AGM” on the battery label or model number. Check if it is non-spillable, sealed, and maintenance-free. Gently shake it; if you hear liquid, it’s not AGM. Use a voltmeter to measure voltage for performance verification. Always double-check with manufacturer information.
Assessing the health of an AGM battery involves a few critical steps. First, measure the voltage using a multimeter. A healthy AGM battery typically registers between 12.6 to 12.8 volts when fully charged. If the voltage falls below 12.4 volts, the battery may need charging or indicate deterioration. Additionally, inspect the battery for any signs of damage or swelling, which can suggest internal issues.
To evaluate the status of an AGM battery, perform a load test. Apply a load equivalent to half of the battery’s rated capacity for 15 seconds. A significant voltage drop indicates weakness and potential failure. Regular maintenance, such as keeping terminals clean and checking against manufacturer guidelines, helps prolong battery life.
Understanding these aspects of AGM batteries sets the stage for addressing maintenance strategies and troubleshooting common issues, ensuring reliable performance and longevity.
