Industrial Battery Chargers
Big Boss Titanium Gold 30
Big Boss Titanium Gold 30 heavy-duty industrial charger for all types of lead-acid batteries, with MCB 1–4 charging-level selection, ISOLATOR 4 mains switch, 0–50 A analog ammeter and heavy-duty output terminals.
Overview
The BIG-BOSS Titanium Gold 30, manufactured by MGA, is an industrial-grade, heavy-duty and professional-grade battery charger designed for demanding commercial and industrial environments, combining power, precise current control and robust safety mechanisms.
It is engineered to optimize the performance, efficiency and lifespan of a wide variety of lead-acid batteries, and serves automotive workshops, industrial facilities and power backup management sectors. For use only in industries or service centres.
Technical Features & Interface
- Multi-Stage MCB Control SystemA heavy-duty Miniature Circuit Breaker (MCB) panel for precise current management and system protection. MCB 1 / MCB 2 / MCB 3 / MCB 4 select distinct charging current levels to match varying battery capacities; ISOLATOR 4 (MAINS) ON/OFF is the master switch, providing a clean physical disconnect from the main power supply.
- Dual Status LED IndicatorsMAINS LED shows the status of the incoming power supply; CHARGING LED confirms that the charging cycle is active and current is flowing to the battery.
- Analog AmmeterReal-time monitoring of the charging current, so technicians can see the charging rate at a glance, assess battery health and ensure the battery draws current within safe limits. Clear 0–50 A scale.
- Heavy-Duty Output TerminalsPremium heavy-duty terminals handle continuous high-current flow and provide a strong, secure, vibration-resistant connection for spark-free operation.
Key Benefits
- Fast & Efficient Battery ChargingAn advanced internal circuit and rectification help rapidly charge even fully discharged batteries.
- Universal Lead-Acid CompatibilityServices all types of lead-acid batteries: inverter batteries, automotive (car/truck/heavy equipment) batteries and tubular (deep-cycle) batteries.
- Rugged & Durable ConstructionA heavy-duty metal chassis designed to withstand harsh industrial floors, warehouses and workshops.
- Built-In Operating InstructionsStep-by-step guidelines are printed directly on the front of the unit for easy reference.
- Safe & Reliable OperationBuilt-in MCB protection prevents overcurrent hazards.

Operating Instructions
- Earth the chargerLoosen the earthing nut, take a wire and connect the charger to earth.
- Safety checkEnsure ISOLATOR 4 (MAINS ON/OFF) is in the OFF position and the AC mains supply is off. Check that terminal leads and battery posts are clean, free of corrosion and securely fastened.
- Connect the batteryConnect the RED cable from the charger's positive (+) terminal to the battery's positive terminal, and the BLACK cable from the negative (−) terminal to the battery's negative terminal. Tighten all terminal screws securely to avoid sparking.
- Power onCheck the phase with a tester and connect the red wire to phase and the black wire to neutral. Select the charging level with the charging MCB switch, then switch ISOLATOR 4 ON. The MAINS LED lights up.
- Monitor chargingThe CHARGING LED glows once charging begins; the charging current can be read on the ammeter.
- Power off & disconnectTo change the charging level or disconnect, first switch ISOLATOR 4 OFF and turn off the AC mains. Disconnect the BLACK (−) cable first, then the RED (+) cable.
Safety Precautions & Warnings
- Industrial use only – this equipment is not intended for household use.
- Designed exclusively for recharging lead-acid batteries. Do not attempt to charge non-rechargeable or lithium-ion batteries.
- Operate in a well-ventilated, dry and dust-free area. Lead-acid batteries emit explosive gases during charging; keep sparks, flames and lighted cigarettes away.
- Always ensure the power switch is OFF before connecting or disconnecting the terminal clamps.
- Wear appropriate PPE, including safety glasses and protective gloves.
- In the event of a short circuit or sparking, immediately turn OFF ISOLATOR 4 (MAINS) and safely disconnect the battery.
Highlights Across All Models
- Amperage control technologyPeriodically check the battery and remove it from the charger once it is fully charged.
- Copper wiringAll wires are made of copper.
- Operator safetyAlways use shockproof gloves.
