To identify an AGM battery, look for labels that say “AGM” or “non-spillable.” Check the battery design; AGM batteries are sealed and vibration-resistant. Gently shake the battery; if you hear liquid, it isn’t AGM. AGM stands for Absorbent Glass Mat, which absorbs acid and keeps the battery spill-proof. Make sure to check the vehicle VIN for compatibility.
AGM batteries typically exhibit a deeper discharge capability, allowing them to provide more power for longer periods than standard lead-acid batteries. They also charge faster and perform better in cold temperatures. Conversely, standard lead-acid batteries are generally cheaper and widely available, making them easier to replace.
Weight is another differentiating factor. AGM batteries are lighter than their lead-acid counterparts due to their compact design. Additionally, AGM batteries have a longer lifespan, often lasting two to three times longer than standard lead-acid batteries.
Understanding these key differences can help consumers make informed decisions about which battery type fits their specific needs.
