Battery charger Voltcraft BC800 for 6V and 12V lead-acid batteries, max current 0.8 A

Voltcraft BC800 is a compact battery charger designed for charging and maintaining 6V and 12V lead-acid batteries with a maximum charging current of 0.8 A. The unit is intended for slow, controlled charging and trickle maintenance, helping to keep starter and small deep-cycle batteries topped up and extending overall battery life when used according to instructions.

Advantages

The compact form factor of the Voltcraft BC800 simplifies storage and installation in garages or workshops, while the low maximum current of 0.8 A provides gentle charging suitable for small capacity batteries and long maintenance cycles. The charger supports both 6V and 12V lead-acid battery types, enabling use with a range of vehicles and equipment. Built-in safety features and a simple user interface reduce the risk of overcharging when used correctly.

• Maximum charging current: 0.8 A
• Charging mode: slow/maintenance charging suitable for trickle charge cycles
• Intended battery chemistries: lead-acid (including flooded and sealed types commonly used in starter and small deep-cycle applications)
• Form factor: compact, lightweight charger for fixed or occasional use

How to use

Connect the Voltcraft BC800 to the battery according to the polarity markings: positive clamp to the battery's positive terminal and negative clamp to the negative terminal or a suitable chassis ground. Select the appropriate voltage setting (6 V or 12 V) before connecting mains power. After connecting, switch on the charger and monitor charging progress following the manufacturer's guidance. For maintenance charging, allow the unit to remain connected for extended periods as needed to keep the battery at optimal charge. Always disconnect mains power before removing clamps.

Usage recommendations

The charger is suitable for slow and maintenance charging; avoid using it as a rapid charger for heavily discharged large-capacity batteries. Check battery manufacturer recommendations for charge voltage and accept that some deep-cycle or specialized batteries may require dedicated chargers. Ensure good ventilation, avoid exposing the charger to moisture, and inspect clamps and cables for damage before each use.
