The Wacker Neuson 5100012544 Battery is a genuine OEM Battery designed for the RD-series tandem rollers, covering the RD18, RD24, RD27, RD28, RD40, and RD45 model families. Sourced directly from Wacker Neuson, this OEM Battery delivers the correct output specifications required to start and power these walk-behind and ride-on articulated tandem rollers under demanding jobsite conditions. Fitment spans a wide range of RD-series configurations including standard, combination, and open-platform variants across multiple production runs.
Key Features
- OEM-Matched Output Specification — Engineered to the exact voltage and cold-cranking amp rating required by RD-series tandem roller electrical systems, ensuring reliable engine starts and stable onboard power delivery.
- Direct Drop-In Replacement — Matches the original battery's terminal configuration and physical dimensions for a straightforward swap with no additional hardware or modifications.
- Broad RD-Series Compatibility — Confirmed fitment across RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller families, including standard, combination drum, and open-platform variants.
- Protects Sensitive Roller Electronics — A correctly rated battery maintains stable voltage to onboard controls and vibration system electronics; an underperforming battery can cause erratic operation or failure to start on a warm or cold engine.
- Genuine Wacker Neuson OEM Part — Carries the Wacker Neuson part number 5100012544 and meets the same build standards as the battery installed at the factory, giving you a known-quantity replacement backed by the manufacturer.
The battery is the primary electrical storage and delivery component in a tandem roller's powertrain. It supplies the high-amperage burst needed to crank the diesel engine and continues to support the machine's electrical systems — including ignition, controls, and vibration circuit management — once the engine is running. A battery that is weak, sulfated, or failing to hold a full charge will cause hard starts, voltage drop to sensitive electronic controls, and potential mid-shift shutdowns. Replacing a worn battery with the correct OEM unit restores full electrical capacity and keeps all onboard systems operating within spec.
