Tecmate Optimate DC to DC, TM-500v3, 6-Step 12V/12.8V 2A Sealed - TecMate

The TecMate Optimate DC to DC, TM-500V3, is a robust 6-step 2A charger engineered for professional automotive and industrial applications, providing efficient charging of secondary 12V lead-acid or 12.8V LiFePO4 batteries from an existing 12V power source. This versatile unit ensures critical auxiliary batteries remain optimally charged and maintained in various mobile or remote setups, extending their lifespan and ensuring reliable operation.

Key Features

• DC-to-DC Charging Capability: Efficiently charges a secondary 12V battery from any 12V DC power source, such as a vehicle's primary battery or an existing 12V supply.
• Advanced 6-Step Charging Algorithm: Utilizes a precise multi-stage program to optimize battery health, perform desulfation on lead-acid batteries, and ensure long-term maintenance without overcharging.
• Dual Voltage & Chemistry Support: Automatically detects and safely charges both standard 12V lead-acid batteries (SLA, AGM, Gel) and 12.8V Lithium Iron Phosphate (LiFePO4) batteries.
• Automatic Maintenance Mode: Transitions to a safe, long-term maintenance cycle once the battery is fully charged, preventing discharge and sulfation to prolong battery life.
• 2 Amp Output Current: Delivers a steady 2A charge, suitable for maintaining smaller auxiliary batteries or for the long-term care of larger battery banks.

Applications

• Recreational Vehicles (RVs) & Campers: Charges auxiliary "house" batteries from the vehicle's primary starter battery while driving, ensuring continuous power for onboard appliances and electronics.
• Marine Vessels: Maintains boat service batteries using the engine's starter battery, providing reliable power for navigation, lights, and accessories during extended trips or mooring.
• Off-Grid Systems: Offers a self-contained charging solution for 12V storage batteries in remote cabins, sheds, or portable power setups where a 12V DC power source is available.
• Work Vehicles & Utility Carts: Ensures secondary batteries for specialized equipment, lighting, or communication devices remain charged from the vehicle's main electrical system, critical for uninterrupted operation in professional environments.
