Battery Heaters

Battery heater mats discussed here are stationary accessories designed to warm backup power batteries inside enclosures, not portable space heaters powered by batteries. They mount directly to battery cases in traffic cabinets, UPS systems, or telecom enclosures to maintain performance in freezing temperatures rather than heating open spaces or rooms.

Battery heater mats maintain batteries at optimal operating temperature, preventing the capacity loss and reduced runtime that occur in freezing conditions. By directing heat specifically to the battery rather than the enclosure, they help ensure traffic signals, ITS equipment, and telecom systems maintain reliable backup power during outages, even in sub-zero weather.

Battery heater mats are commonly available in 120V configurations, with piggyback plugs standard for straightforward installation alongside existing power connections. This allows the heater to draw power directly from the same circuit as the battery charger or UPS system without requiring additional wiring or outlets.

Yes, battery heater mats are designed as accessories for traffic cabinet UPS and backup power enclosures, including NEMA and Type 3R rated cabinets. They integrate with battery compartments to protect AlphaCell and similar backup batteries used in traffic signal, ITS, and roadway lighting power systems.

Quality battery heater mats include redundant safety systems such as an on-mat thermal switch and a thermal fuse, which prevent overheating. Sealed electronics protect internal components from moisture, dust, and temperature extremes, ensuring safe, reliable operation in outdoor traffic and ITS enclosures year-round.

Insulated battery heater mats direct heat specifically to the battery rather than warming the entire enclosure, which can reduce battery heating costs by up to 30% compared to enclosure heating alone. This targeted approach conserves energy while keeping backup batteries within their optimal operating temperature range.
