The Wacker Neuson 5200021677 Battery Box Kit is a genuine OEM component designed for the APT-series self-priming centrifugal trash pump lineup. This kit supplies a direct-fit, fully matched battery enclosure assembly for APT4S, APT4T, APT6S, APT6T, APT8S, and APT8T pump configurations — including standard, skid-mount, surge brake, electric brake, and cold weather variants. As a genuine Wacker Neuson part, the 5200021677 is manufactured to the same specifications as the original unit, ensuring proper fitment and function across the full APT pump family. When the battery box is cracked, corroded, or otherwise compromised, replacing it promptly with the correct OEM kit keeps your pump's electrical system protected and operational.
Key Features
- Genuine OEM Enclosure Construction — Manufactured to Wacker Neuson's original material and dimensional standards for the APT pump battery housing, ensuring the box seats, seals, and secures exactly as intended.
- Complete Kit Format — Supplied as a ready-to-install kit with all necessary enclosure components, eliminating the need to source individual hardware separately.
- Broad APT-Family Coverage — Fits APT4S, APT4T, APT6S, APT6T, APT8S, and APT8T pump models across standard, skid-mount, surge brake, electric brake, and cold weather configurations.
- Protects Electrical Integrity — A sound battery box shields the pump's battery and connected electrical components from moisture, debris, and physical damage — a failed or cracked enclosure exposes sensitive components to conditions that can cause electrical faults or pump failure.
- Electrical System Safety — Correct battery containment is essential on pump units with electric brake systems; a properly secured and enclosed battery prevents unintended discharge and contact hazards during transport and operation.
The battery box on an APT-series pump serves as the protective housing for the onboard battery that powers the pump's electric control and braking systems. It keeps the battery securely mounted and isolated from water, mud, and mechanical impact that are common in pump deployment environments. When the battery box cracks, warps, or loses its mounting integrity, the battery becomes vulnerable to short circuits, corrosion, and physical displacement — any of which can disable the pump's electric functions or create a safety hazard, particularly on trailer-mounted units equipped with electric brake systems.
