Weldman Weldman CHARGE 400 12V/24V rectifier battery charger/maintainer

Weldman CHARGE 400 12V/24V rectifier battery charger/maintainer is a mains-powered device engineered to charge and maintain lead-acid vehicle batteries used in cars, vans and trucks. The unit provides controlled rectified DC output for safe charging and a low-current maintenance mode for long-term battery upkeep. Designed for workshop and fleet environments, this charger accommodates both 12 V and 24 V electrical systems and is suitable for routine charging, topping up and trickle maintenance of conventional lead-acid batteries.

Advantages

The charger delivers steady rectified DC current tailored to lead-acid batteries, reducing risk of overcharging while enabling efficient charge cycles. Its dual-voltage capability eliminates the need for separate chargers for 12 V and 24 V vehicles, simplifying workshop inventory. Built for continuous connection in maintenance mode, it supports long-term battery preservation for stored or infrequently used vehicles. Construction and controls are optimized for regular use in service environments and fleet maintenance operations.

Suitable for

• Charging and maintaining 12 V lead-acid batteries in passenger cars and light vans
• Charging and maintaining 24 V lead-acid batteries in trucks and commercial vehicles
• Fleet depots and workshops performing routine battery upkeep
• Seasonal or long-term vehicle storage where trickle maintenance is required

Key specifications

• Input: mains AC power (typical for workshop chargers)
• Output: rectified DC suitable for lead-acid battery charging
• Selectable operation for 12 V and 24 V battery systems
• Maintenance/trickle charge mode for long-term connection
• Intended battery chemistry: lead-acid (conventional)
• Application environment: workshop, garage or fleet maintenance

How to use

Connect the charger to the mains supply and select the appropriate voltage (12 V or 24 V) according to the vehicle battery system. Attach the charger clamps to the battery terminals, ensuring correct polarity. Start the charging cycle and monitor charge progress if the unit provides indicators or meters. Once the battery is charged to the recommended level, switch the device to maintenance/trickle mode if long-term connection is needed, or disconnect the charger following the manufacturer’s safety procedures.

Usage recommendations

Use the charger only with compatible lead-acid batteries and follow vehicle manufacturer guidelines for recommended charging voltages and currents. Ensure good ventilation, avoid connecting to frozen batteries, and verify correct polarity before switching the unit on. Regularly inspect cables and connections for wear and replace damaged parts. For mixed 12 V and 24 V fleets, confirm correct voltage selection before charging each vehicle.
