Stihl AL 5-2 Hi-speed double battery charger (AS Battery)

Eliminate the waiting game with the STIHL AL 5-2, the high-velocity dual charging hub designed specifically for the AS 2 battery ecosystem. While standard chargers like the AL 1 can leave you sidelined for over an hour, the AL 5-2 uses a high-current 4A delivery system to charge two AS 2 batteries simultaneously to 80% in just 30 minutes. Whether you are powering the GTA 26 pruner, the HSA 26 shears, or the SEA 20 vacuum, this dual-port powerhouse ensures that one battery is always ready to go the moment the other is depleted. Engineered for the professional or the dedicated home gardener, the AL 5-2 isn’t just a charger—it’s a productivity multiplier that doubles your uptime and halves your footprint. Simultaneous 4A High-Speed Pulse: Unlike “sequential” chargers that finish one battery before starting the next, the AL 5-2 delivers a dedicated 4A current to both ports at once. This effectively cuts your total fleet charging time by 60% compared to using two standard chargers. On-Board Thermal Balancing: Each port is equipped with a digital sensor that communicates with the AS 2 battery’s BMS (Battery Management System). If one battery is hot from use, the charger intelligently manages the current flow to prevent cell degradation while prioritizing the cooler battery. Master-Status LED Matrix: Features two independent, high-visibility flashing LED patterns. At a glance, you can differentiate between a “cool-down” phase, a 80% rapid-charge state, and a 100% trickle-finish, so you never grab a half-full battery by mistake. Compact “Command Center” Wall Mount: Designed with integrated keyhole slots and a built-in Velcro cable management strap, the AL 5-2 transforms your workshop wall into a clean, organized charging station, saving precious bench space. Voltage Surge Protection: Built with industrial-grade internal fuses, the AL 5-2 protects your expensive lithium-ion investment from the voltage spikes and brownouts common in domestic Irish power grids. Energy-Efficient 0.1 kW Draw: Despite its high-speed output, the charger is engineered for low power consumption ($120 \text{ W}$), making it safe to run on small van inverters or portable power stations for off-grid work.
