The GKL221 4 Slot Charger is engineered with that reliability in mind. It’s ideal for surveyors, construction engineers, and field technicians who need multiple Leica batteries ready for long days of precise measurement, mapping, and data collection.Unlike single-bay chargers that limit productivity, this 4-slot model allows simultaneous charging of up to four Leica-compatible batteries — ensuring uninterrupted workflow and reduced charging downtime.Broad Compatibility Across Leica GEB-Series BatteriesThe GKL221 4 Slot Charger supports a wide range of Leica GEB-series batteries, making it a versatile choice for professionals using various Leica systems.Compatible Battery Models:GEB221 GEB212 GEB111 GEB171 GEB241 GEB70 This universal compatibility means you no longer need multiple chargers for different Leica devices. From GNSS receivers to Total Stations and Controllers, this single charger handles them all efficiently.Smart Charging Technology with Intelligent Power RegulationEach charging bay of the GKL221 operates independently, powered by an intelligent microprocessor that identifies the battery type and condition before charging begins. The charger automatically adjusts the current and voltage to deliver an optimized charging cycle for each slot.Benefits of Smart Charging:Detects battery type automatically Adjusts voltage/current per battery Prevents overcharging and overheating Extends overall battery lifespan Allows simultaneous, balanced charging across all four bays The smart charging logic ensures each battery is charged safely and efficiently without performance degradation.Faster Charging with Optimized EfficiencyWith traditional single-bay chargers, surveyors often have to wait for one battery to finish before charging another. The GKL221 4 Slot Charger eliminates this bottleneck.Each bay operates independently, enabling up to four batteries to charge at the same time without compromising charging speed or safety. Typical charging time is between 2 to 3 hours per battery, depending on capacity and condition.This fast, efficient design minimizes idle time and ensures that you always have charged batteries ready when you need them.Compact, Durable, and Field-Ready DesignSurveying equipment faces demanding environments — from dusty construction sites to outdoor field setups. The GKL221 4 Slot Charger is built with robust, durable materials that can handle everyday wear and tear.Design Highlights:Compact footprint fits easily into tool bags or equipment cases Reinforced outer shell protects internal components Lightweight and portable for on-site use Non-slip base for stable placement during charging Whether used in the office or the field, it’s built to perform wherever your job takes you.LED Charging Indicators for Real-Time MonitoringClear and intuitive LED lights keep you informed about the status of each charging slot.LED IndicatorMeaningRedCharging in progressGreenBattery fully chargedBlinking RedError or incompatible battery detectedThis makes it easy to monitor progress at a glance — no guesswork, no interruptions.Enhanced Safety and Battery ProtectionBattery safety is crucial when working in professional environments. The GKL221 4 Slot Charger incorporates multiple layers of electrical and thermal protection, ensuring both user and device safety.Built-In Safety Mechanisms:Over-voltage protection Over-current protection Over-temperature control Short-circuit prevention Reverse polarity safeguard These integrated protections not only prevent damage to the charger and batteries but also help prolong battery health and efficiency over time.Perfect for Professional Leica UsersThe GKL221 4 Slot Charger is ideal for professionals who use Leica GNSS receivers, Total Stations, controllers, or data loggers daily. It ensures that every battery in your toolkit is charged and ready for use.Compatible Leica Equipment Includes:Leica GNSS Receivers (GS10, GS15, GS16) Leica Total Stations (TS11, TS15, TS16) Leica Controllers (CS10, CS15, CS20) Leica Digital Levels, Laser Scanners, and Field Equipment Whether you’re working on construction sites, infrastructure surveys, or geodetic mapping, this charger helps maintain smooth operations with minimal downtime.How to Use the GKL221 4 Slot ChargerCharging your Leica batteries is quick and straightforward:Connect the Charger Plug the GKL221 into a 100–240V AC outlet using the provided power cord. Insert the Batteries Place up to four compatible GEB batteries into the charging bays. Ensure each one fits snugly. Monitor the LED Lights Red = Charging Green = Fully Charged Blinking Red = Error or incompatible battery Remove and Store Once charging is complete, remove the batteries and store them for use. Maintenance Tips for Long-Term PerformanceStore in a cool, dry place away from direct sunlight. Avoid charging in wet or humid environments. Clean the contacts occasionally to ensure efficient current transfer. Use only with genuine or compatible Leica batteries. Unplug when not in use for extended periods. Proper care ensures your charger delivers years of reliable service.Technical SpecificationsSpecificationDetailsModelGKL221 4 Slot ChargerInput Voltage100–240V AC, 50–60HzOutput CurrentAuto-adjusted per slotCharge Time2–3 hours typicalSlots4 independent baysDimensions180 x 100 x 45 mmWeight~650gOperating Temp.0°C to 40°CStorage Temp.-20°C to 60°CCertificationsCE, FCC, RoHS compliantWhy Choose the GKL221 4 Slot ChargerCharge Four Batteries at Once – Save time and boost productivity with simultaneous charging.
