Battery Systems Inc. U1XM 12V Tractor Battery 350 Cca

Product Description

The BATTERY SYSTEMS, INC. U1XM is a 12-volt, maintenance-free wet cell battery designed for lawn and garden tractor applications. Delivered fully charged and ready to install, it produces 350 Cold Cranking Amps (CCA) and provides 34 minutes of reserve capacity, making it a reliable replacement for seasonal and year-round outdoor power equipment. The flat top design and fixed positive terminal placement simplify drop-in installation. At 17 pounds, it is sized for standard U1-footprint battery trays found across common tractor platforms. Licensed technicians and experienced DIYers working on outdoor power equipment will find the no-maintenance design reduces service callbacks.

The U1XM is intended for residential lawn and garden tractors and riding mowers that require a Group U1 battery. The wet, charged format means the battery ships activation-ready with no acid-filling or conditioning required before installation. The positive terminal is located on the left side when viewing the battery from the front, a detail critical to verifying cable reach and polarity before installation. This battery is suitable for seasonal or frequent-use equipment where cold-start reliability and reserve capacity are primary concerns.

Installation Notes

Installation should be performed by a qualified technician or knowledgeable equipment owner following the equipment manufacturer's service manual. Disconnect the negative cable first and reconnect it last to prevent accidental short circuits during service. Verify terminal orientation and cable reach before securing the battery in the tray, as reversing polarity can damage the charging system or onboard electronics. Dispose of the old battery at a certified lead-acid battery recycling facility in accordance with local regulations.
