Quick Answer
AGM batteries are generally considered safe for usage in towed trailers, but proper maintenance and precautions must be taken to ensure their longevity and prevent potential hazards.
Understanding AGM Batteries
AGM (Absorbed Glass Mat) batteries are designed with a special separator that absorbs spills and prevents the buildup of gas. This makes them relatively safe for use in enclosed spaces, such as towed trailers. However, improper maintenance and handling can still lead to issues like overheating, overcharging, and acid buildup.
Safety Precautions for AGM Batteries in Towed Trailers
When using AGM batteries in towed trailers, it’s essential to follow these guidelines: charge them in a well-ventilated area, keep them away from direct sunlight, and ensure proper ventilation within the trailer. To prevent overcharging, install a battery management system (BMS) that monitors state of charge, voltage, and temperature. Consider using a deep cycle AGM battery with a high reserve capacity (RC) rating, such as the Deka 8D or the Trojan T105, which have an RC rating of 100-150 minutes.
Maintenance and Inspection
Regular maintenance is crucial to prevent issues with AGM batteries in towed trailers. Check the water level (if applicable) monthly, and top it off as needed. Inspect the terminals and cables for signs of corrosion or wear, and clean or replace them as necessary. Every 6-12 months, perform a load test on the battery to ensure it’s holding a charge. If you notice any issues or concerns, consult the manufacturer’s guidelines or contact a professional for assistance.
