Wacker Neuson 5100021329 Battery

The Wacker Neuson Battery is a genuine OEM Battery designed for a wide range of Wacker Neuson DPU-series vibration plate compactors, including the DPU6555, DPU5545, DPU5260, DPU6260, DPU6275, DPU5275, DPU4545, DPU4045, and DPU40/45 Yeh series machines. Sourced directly from Wacker Neuson, this battery meets the exact electrical specifications required by these Honda-engine equipped reversible and forward-plate compactors. Fitting the is a direct swap into the factory battery position, with no adaptation needed to the tray, terminals, or cabling. If your machine is showing slow cranking, a no-start condition, or is failing to hold a charge, the is the correct OEM replacement to restore full starting performance.

Key Features

• Correct OEM Voltage and Terminal Configuration — Genuine Wacker Neuson spec ensures the battery outputs the precise voltage and cold-cranking characteristics these Honda-engine compactors require for reliable starting across varying temperatures.
• Direct Drop-In Replacement — Matches the factory battery tray footprint and terminal orientation on DPU-series plate compactors, slotting in without modification to the hold-down bracket or cable connections.
• Broad DPU-Series Fitment — Compatible across DPU6555, DPU5545, DPU5260, DPU6260, DPU6275, DPU5275, DPU4545, DPU4045, and DPU40/45 Yeh series vibration plates, covering He, Heh, Hech, Heap, and related variants.
• Restores Full Engine Starting Power — A healthy battery delivers the sustained cranking current the electric-start Honda engine needs; a weak or failed battery leads to hard starts, failed ignition cycles, and lost productivity on compaction work.
• Electrical System Safety — Using a correctly rated OEM battery prevents under-voltage conditions that can stress the charging circuit and starter motor, protecting the broader electrical system from premature wear.
• Genuine OEM Part — Part number 5100021329 is an authorized Wacker Neuson component, ensuring it matches the original design intent for these machines without substitution or compromise.

The battery on a DPU-series vibration plate compactor powers the electric start system, supplying the high-current burst needed to crank the Honda engine and engage the ignition circuit. Once the engine is running, the battery is recharged by the onboard charging system and held in reserve for the next start cycle. When the battery degrades — losing capacity, failing to hold a charge, or delivering insufficient cranking amps — the engine becomes difficult or impossible to start, leaving the compactor inoperable on site. Replacing a worn battery with the correct OEM unit, such as the Wacker Neuson 5100021329, ensures the starting system operates exactly as engineered and protects the starter motor from the strain of repeated failed crank attempts.
