AGM batteries are most commonly killed by deep discharges and chronic undercharging, which cause sulfation and reduced capacity. Overcharging or using an improper charger can also damage the battery by causing overheating, excessive gassing, and plate degradation. To maximize battery life, always maintain a proper charge using a charger specifically designed for AGM batteries and select a charger with the correct amperage for your specific battery. The correct charging amperage is calculated based on your battery’s capacity—typically around 20-30% (AGM only) of its amp-hour rating—to prevent excessive heat or insufficient charging, so always check your battery manufacturer's recommended charge rate. Regularly maintaining the battery’s charge level with a correctly paired, quality charger will help ensure your AGM battery lasts for years.
