500A Angled Battery Disconnect Switch

Brief Overview

This 500A angled battery disconnect switch is engineered for professional service technicians and fleet operators who require reliable battery isolation during maintenance, storage, and security applications. Whether you're disconnecting a vehicle for extended downtime, preventing parasitic battery drain, or adding theft deterrent functionality, this switch delivers straightforward mechanical reliability across automotive, marine, RV, and equipment applications. Its angled terminal design accommodates tight battery compartment configurations without requiring cable rerouting.

Key Features

• 500A Crank Rating – Handles maximum cranking load without thermal degradation
• 125A Continuous Rating – Safe for extended parasitic draw elimination during storage
• Brass-Plated Metal Construction – Corrosion-resistant terminal contact with gold-colored finish
• Angled Terminal Design – Fits compact battery compartments; reduces sharp bends in battery cables
• Insulated Rotating Collar – Green plastic knurled knob for secure, tool-free operation; color-coded for quick identification
• U-Shaped Clamp Assembly – Accommodates standard battery post diameters without modification
• Negative Polarity Configuration – Pre-configured for standard automotive negative-ground systems
• Wide Temperature Operating Range – Performs reliably from -40°C to +90°C (handles arctic service and tropical climates)
• Cable Compatible – Accepts 4-6 AWG cable sizes (standard automotive battery cables)
• 17.5mm Terminal Diameter – Universal fit across passenger vehicles, light trucks, and marine batteries

Why Resellers Choose This Switch

Mechanic Confidence: Technicians trust mechanical switches over electronic isolation systems because there's no relay failure, no parasitic draw from the switch itself, and no diagnostics needed. One hand-turn disconnects the battery completely.

High-Margin Upsell: Bundle this with battery service kits, storage packages for seasonal vehicle storage, or marine winterization services. Customers expect it when they hear "battery disconnect."

Fleet & Commercial Appeal: RV parks, boat storage facilities, and commercial fleet managers stock these for routine vehicle prep. Bulk orders for fleet management are common.

Theft Deterrent Positioning: Unlike an expensive GPS tracker, this is a low-cost, visible security measure. Resellers can position this as "basic battery security" during vehicle sales or service intervals.

Durable Inventory Asset: No expiration, no consumable parts, survives warehouse storage indefinitely. No warranty overhead.

Professional Application Context

This switch excels in scenarios where vehicles sit for extended periods: seasonal storage, fleet downtime, caravan winter prep, or boat layup. It eliminates the 10-50mA parasitic drain that keeps batteries depleted during storage. For service shops, it's the standard isolation tool during electrical diagnosis—safer and faster than terminal removal.

The angled terminal orientation prevents stress on battery posts and cable routing, which is particularly valuable in modern vehicles with tight engine compartments or unconventional battery placement (such as underbody or trunk-mounted batteries in some European vehicles).
