SIP STARTMASTER PWT1400 Battery Starter Charger [05539]

The SIP 05539 is the flagship model in the Startmaster range, representing an industrial-tier mobile charging and emergency starter workstation manufactured in Italy. Built into a heavy-duty metal chassis, this wheel-mounted machine delivers a massive 700A maximum boost rate alongside a highly adaptable 6-stage charging configuration. It is engineered specifically for commercial vehicle repair complexes, heavy plant depots, logistics hubs, and agricultural fleet maintenance yards requiring maximum starting current and high-capacity battery conditioning.

Key Features & Benefits

• Dual 12V/24V Heavy Industrial Output: Provides complete workshop coverage, making it equally capable of maintaining standard 12V automotive batteries, light commercials, and vans, as well as 24V heavy-duty commercial trucks, buses, and plant machinery.
• Massive 700A Emergency Boost Current: Engineered to deliver up to 700A of cranking power, allowing operators to jump-start large-capacity engines even when the onboard vehicle battery is completely drained.
• 6 Variable Charge Rate Settings: Outfitted with six distinct charging profiles for absolute precision, giving technicians the flexibility to select anything from a low-amperage maintenance trickle up to an aggressive 90A rapid charge cycle.
• Remote Hand Switch for One-Person Operation: Includes a convenient remote starting lead, enabling a single technician to safely manage the boost function from the driver's seat while cranking the engine.
• Integrated Charging Timer: Features an on-board timer assembly for automated control over fast-charging sessions, improving garage efficiency and preventing accidental overcharging.
• Universal Chemical Range: Formulated to safely manage all mainstream automotive lead-based chemistries, including standard Lead-Acid, SLA, AGM, GEL, flooded WET cells, and sealed VRLA batteries.
• Triple Protection Architecture: Built with integrated safety mechanisms, including reverse polarity warning, short-circuit protection, and thermal overload cutouts to protect the vehicle's electronic architecture, the battery, and the technician.
• Heavy Steel Wheel-Mounted Chassis: Encased in a highly durable, impact-resistant metal enclosure fitted with smooth-rolling transport wheels and an ergonomic top handle for effortless repositioning of the 30.84kg unit.
• 2-Year Warranty: Supported by the standard SIP 2-Year Standard Silver Warranty for trade-level assurance.
