Firehouse battery charging is a common culprit for poor battery performance aboard firehouse vehicles. While plugged in at the station, battery chargers tend to overcharge batteries (even when chargers claim otherwise). The result of overcharging is early battery replacement, batteries that discharge too quickly, and increased risk of dead batteries.


Merlin is adapting its power-management solutions for the US military to the frontlines at home:

KNOWLEDGE IS POWER: For less than the cost of a battery, Merlin’s battery monitoring provides always accurate State of Charge; trigger audio or visual alarms to know when in-station battery chargers should initiate or terminate; or integrate with auto-eject plugs to automate the process.

LIGHT MY FIRE: Emergency and flood lighting can drain batteries even if the engine is running. Permanent battery damage has already occurred by the time lighting dims. Merlin’s dead-battery protection provides timely warnings to address power problems.

RELIABILITY: Properly charging batteries keeps them healthier longer. Merlin’s intelligent Split Charging optimizes the power balance across vehicle electrical systems. Power is directed where it is needed most, avoiding damaging overcharging and excessive discharging.

MODULAR, SCALABLE, INTEGRATED: Merlin’s solutions are available as individual, modular components, and integrated multi-component units; can address any number of battery banks.
