The Multiquip EM491344 Battery 12V is a genuine OEM replacement designed for the LS300 hydraulic-driven concrete pump. As a direct OEM component, it meets the exact electrical specifications required by the LS300's starting and control systems, ensuring dependable cranking power and stable voltage output from the first turn of the key. DHS Equipment stocks this part to keep your Mayco concrete pump running without interruption on the pour.
Key Features
- Correct Voltage Output — Delivers the 12V rating matched to the LS300's electrical system, preventing under-voltage faults or starter damage caused by an undersized or incompatible battery.
- Genuine OEM Component — Sourced directly from Multiquip, this battery meets the same electrical capacity and terminal configuration as the unit installed at the factory on the LS300.
- Direct-Fit for LS300 Concrete Pumps — Engineered specifically for LS300 Mayco series equipment; installs into the existing battery tray and connects to OEM terminals without modification to cables or hardware.
- Consistent Starting Power — Maintains the cold-cranking and reserve capacity needed to reliably fire the LS300's diesel engine, even under demanding jobsite conditions or extended idle periods.
- Electrical System Protection — A correctly rated OEM battery protects the pump's solenoids, control board, and hydraulic valve circuits from voltage irregularities that can result from using an out-of-spec replacement.
The 12V battery is the primary electrical power source for the LS300 concrete pump, supplying the current needed to start the engine and sustain the control circuits, solenoids, and instrumentation during operation. A weak or failed battery can prevent the machine from starting, cause erratic hydraulic valve behavior, or result in mid-pour shutdowns — all of which disrupt concrete placement schedules. Replacing the battery with the correct OEM-spec unit restores full electrical integrity and ensures every system on the pump responds as intended.
