The Bomag 77053221 Empty Battery is a genuine OEM component designed for Bomag BW 75 ADL and BW 75 AD walk-behind light rollers, BW 90 S walk-behind light rollers, and BW 850 T, BW 850 TR, BW 85 T, and BW 1050 T trench compactors. As a direct OEM replacement, this battery casing matches the original housing specification so it seats correctly in the battery compartment without alteration. Sourced directly from Bomag, part number 77053221 carries the same fit and form as the component installed at the factory, giving you confidence in a straightforward swap during scheduled service or unplanned replacement.
Key Features
- Genuine OEM Housing Integrity — produced to Bomag's original casing dimensions and terminal configuration, ensuring the empty battery shell accepts the correct cell type without fitment issues
- Direct Drop-In Replacement — engineered to the same profile as the original unit, this battery installs directly into the battery tray on compatible machines with no trimming or bracket modification
- Broad Model Coverage — fits BW 75 ADL, BW 75 AD, and BW 90 S walk-behind light rollers, as well as BW 85 T, BW 850 T, BW 850 TR, and BW 1050 T trench compactors
- Correct Terminal Alignment — OEM-matched terminal positioning prevents reverse-polarity installation errors and supports a clean, secure electrical connection to the machine's starting circuit
- Supports Scheduled Maintenance — replacing a degraded or damaged battery housing at the right interval keeps the electrical system performing as intended and avoids ignition or starting faults in the field
The battery on a walk-behind roller or trench compactor provides the stored electrical energy needed to crank the engine and power accessory circuits such as lighting and controls. An empty battery casing — the outer housing — must maintain its structural shape and terminal integrity to hold the internal cells securely and conduct current reliably. When the housing cracks, swells, or corrodes, it can cause intermittent starting failures, poor terminal contact, or electrical shorts that interrupt machine operation. Replacing the casing with a correct OEM unit, part number 77053221, restores the integrity of the battery assembly and the dependability of the machine's electrical starting system.
