Price: $49.99 | Compatible Batteries: GEB111 (2100mAh NiMH), GEB121 (4200mAh NiMH); Matched Instruments: TC402, TCR402, TC702, TC802, TPS400, TPS802 Classic Total Station Series
This OEM-spec GKL112 dual-scenario charger solves common field charging pain points: single-use home-only chargers unable to charge on survey vehicles, inferior generic chargers causing NiMH battery memory effect & capacity attenuation, inaccurate charging current leading to incomplete full charge, broken original factory charging dock, lack of overcharge/overheat safety protection, and unclear indicator lights unable to judge power status. Built-in microprocessor intelligent charging chip follows Leica original charging curve, supports both household AC mains and 12V vehicle cigarette lighter power supply, fully charging dedicated camcorder-style NiMH batteries for classic TPS400/TPS802 total stations.

Product Overview
The Leica GKL112 portable survey battery charger with official OEM article number 734753 is a dedicated single-slot charging dock exclusively designed for Leica GEB111 and GEB121 NiMH survey batteries, matching classic TC/TPS400/802 series total stations. Complete set includes charging base, global wide-voltage AC power adapter, and coiled 12V car cigarette lighter charging cable for indoor office and on-road field emergency charging. Built-in independent intelligent charging management MCU chip, automatically identifies battery capacity and switches constant current/constant voltage charging mode, with automatic trickle maintenance charging after full capacity. Shell adopts thickened flame-retardant matte ABS plastic, dustproof, moisture-proof, drop-resistant, adapting to construction site, mine and highway all-terrain survey harsh environments. Precision gold-plated spring contact shrapnel on the slot ensures stable conduction without loose contact after repeated battery insertion and removal.
Core Advantages & Practical Structural Design
- 1:1 OEM charging circuit scheme consistent with original Leica GKL112 charger, direct plug-and-play replacement for damaged factory charging docks
- Dual power supply design: AC 100-240V wide voltage household power + DC 12V vehicle cigarette lighter input, meet office pre-charging and field car emergency charging two scenarios
- Microprocessor intelligent control, targeted charging logic for GEB111/GEB121: GEB111 full charge approx 90 mins, GEB121 full charge approx 180 mins, automatic trickle charge to prevent self-discharge
- Multi-layer complete safety protection circuit: overcharge, overheat, overcurrent, short-circuit, reverse connection automatic power-off, effectively avoid battery bulging and fire risks
- Dual-color LED status indicator: Red = charging ongoing, Green = fully charged & maintenance mode, clear real-time battery power state feedback at a glance
- Gold-plated elastic contact terminals, anti-oxidation, stable conduction, no poor contact or charging interruption caused by battery metal surface wear
- Compact integrated split structure, charging dock independent storage, coiled car cable retractable without messy winding, lightweight portable for instrument backpack storage
- Full compatibility: GEB111 & GEB121 NiMH batteries, fully supports TC402/TCR402/TC702/TC802/TPS400/TPS802 classic total station equipment kits
- Compatible matching accessory: Trimble TSC3 / TSC2 Yellow Nylon Carrying Case ($25, 0.2kg, 18 × 12 × 10 cm)
- Small rectangular dock shape, easy to roll and store in accessory pouch together with spare GEB batteries, GEV communication cables and survey brackets
Office & Vehicle Dual-Scenario Charging Application Scenarios
Essential portable power maintenance accessory for highway long-distance survey, mountain mine topographic mapping, rural cadastral boundary measurement, tunnel control survey and construction stakeout projects. Survey teams use AC adapter to fully charge spare GEB batteries overnight in the office before field work; when out for long-distance all-day survey, connect the coiled car charging cable to vehicle cigarette lighter to quickly top up exhausted batteries without searching for external mains power. Intelligent anti-memory-effect charging algorithm slows down NiMH battery capacity decay after hundreds of charge cycles, guaranteeing stable full-day total station measurement without sudden power shutdown. Built-in short-circuit protection avoids circuit burnout when battery contacts accidentally short-circuited during replacement operation. Store this complete GKL112 charger set and other tiny survey peripherals in our high-visibility yellow nylon data collector case; reinforced canvas belt loop supports waist hanging for convenient cross-region field transport.
