The Wacker Neuson Wet Battery Gr31 is a genuine OEM battery designed for the G-series skid-mounted mobile generators and LTW20 series light towers. As a direct OEM replacement sourced from Wacker Neuson, part meets the same electrical specifications as the original unit installed at the factory. This battery spans an exceptionally wide range of G-series configurations — from the G25 and G50 through the G70, G100, G120, G150, G180, G230, G240, and G320 — covering standard, cold-weather, custom, and Tier 4 Final variants, as well as select LTW20Z1 and LTW20Z3 light tower models.
Key Features
- OEM-Spec Group 31 Capacity — Group 31 format delivers the cold-cranking amps and reserve capacity required to start large diesel generator engines reliably across varying ambient conditions.
- Drop-In OEM Replacement — Engineered to match the original battery tray dimensions, terminal orientation, and cable connections of the 5000159808 installation, so no tray modification or cable adaptation is needed.
- Broad G-Series and LTW20 Coverage — Confirmed fitment across G25 through G320 mobile generator families and LTW20Z1/LTW20Z3 light towers, including standard, cold-weather, custom, and Transport Canada-compliant configurations.
- Cold-Weather Starting Performance — Wet-cell chemistry maintains sufficient charge delivery in cold-weather-spec machines where reliable engine cranking is critical to generator availability on site.
- Electrical System Integrity — A correctly specified OEM battery supports stable voltage output to the generator's control panel and AVR circuitry; an underrated or failing battery can cause erratic voltage regulation and nuisance shutdowns.
A Group 31 wet battery serves as the primary electrical storage and engine-starting source for diesel-powered mobile generators and light towers. It supplies the high-current burst needed to crank the engine on startup, and it also powers control panel electronics, safety shutdown circuits, and indicator systems when the engine is off. When a battery weakens or fails, the generator may crank slowly, fail to start in cold conditions, or trigger low-voltage faults in the control system — disrupting power delivery on the jobsite. Replacing the battery with the correct OEM-specified unit ensures the electrical system operates within designed parameters from the first start.
