The Genie 18078GT Charger Timer Relay is a genuine OEM electrical component built for Genie Z-series articulating boom lifts, including the Z-34/22 N, Z-34/22 DC, Z-34/22 Bi-Energy, Z-45/25, Z-45/25J DC, Z-45/25J Bi-Energy, Z-40/23N, Z-40/23N RJ, Z-30/20 N, Z-30/20N RJ, Z-30/20HD, Z-30/20, Z-45/22 MP, Z-25/8, Z-20/8, and Z-20/8N. As a genuine Genie OEM part, the part is manufactured to meet the exact electrical specifications of the original component, ensuring correct operation within the charging circuit it serves. Always cross-reference part number 18078GT against your machine's parts manual to confirm it is the correct relay for your specific unit before ordering.
Key Features
- Genuine OEM Electrical Conformity — Manufactured to Genie's original specifications, ensuring correct switching characteristics and contact ratings for reliable relay operation in the charging circuit.
- Direct-Replacement Fit — Designed to seat and connect exactly as the original, allowing straightforward installation without reworking the existing wiring or mounting.
- Broad Z-Series Compatibility — Fits a wide range of Genie Z-series articulating boom lifts across DC, Bi-Energy, and standard configurations, covering multiple platform variants in one part number.
- Charger Circuit Integrity — A correctly functioning relay ensures the onboard charger cycles as intended. A failed relay can interrupt charging sequences, leaving batteries undercharged and the machine unable to complete a full shift.
- Electrical Safety Assurance — Using the correct OEM relay maintains the designed switching logic in the charging system, helping prevent unintended electrical behavior that could affect machine availability and operator safety.
A charger timer relay is an electrically operated switch that controls when the onboard battery charger activates and deactivates during a charging cycle. On Bi-Energy and DC-powered articulating booms, correct timing of the charger is essential to maintaining battery health and ensuring the machine holds enough charge to operate through a full workday. When this relay fails, the charger may not engage at the right time — or at all — leaving batteries partially charged and the machine unable to meet its rated performance. Replacing a faulty relay with the correct OEM part restores proper charger function and protects the battery system from the wear caused by incomplete charge cycles.
