[MANDATORY] REGULATOR CHECK & EXTERNAL CHARGING: Most older mowers (e.g., Craftsman LT/DLT series) lack full-wave rectifiers. You MUST ensure your charging system is regulated under 15.0V. If unregulated or outputting >15V, you MUST disconnect the mower's internal charging wire and use an external 14.4V-14.6V lithium charger to prevent BMS protection triggers.
GROUP U1R REVERSE POLARITY SPECIFICATIONS: Engineered for equipment requiring Right-Hand Positive (+ on the right) terminals. This U1R-M-480 model is a drop-in replacement for Craftsman DLT 2000, DLT 3000 (27386), LT 1000, GT 3000, and John Deere STX38. Dimensions: 194x123x176mm.
SUPERIOR 480CCA COLD STARTING POWER: Powered by high-rate LiFePO4 cells delivering 480 Cold Cranking Amps (CCA). It provides instant ignition for heavy-duty twin-cylinder engines even after months of winter storage, far exceeding the 230-300CCA performance of standard lead-acid batteries.
INTEGRATED SMART LCD VOLTAGE DISPLAY: Features a built-in digital SOC (State of Charge) screen for real-time voltage monitoring. This allows you to verify your mower's charging output and battery health at a glance, eliminating "dead battery" surprises during the first mow of spring.
IP66 WATERPROOF & ALL-WEATHER DURABILITY: Constructed with a rugged, sealed IP66 housing to resist extreme vibrations, dust, and direct water splashes during deck washing. Optimized to operate reliably in cold temperatures.
70% LIGHTER & 10-YEAR DESIGN LIFE: Weighing only 2.3 kg (5.07 lbs) compared to 8 kg for lead-acid, it reduces equipment weight and eases handling. Offers >2000 deep cycles, providing a decade of maintenance-free service and lower long-term cost.
ADVANCED BMS SAFETY PROTECTION: The internal Battery Management System (BMS) offers 6-way protection against over-charge, over-discharge, and short circuits. WARNING: The BMS will automatically shut down the battery if exposed to unregulated high-voltage stator output (>15.0V).
