The BATTERY SYSTEMS, INC. U1SM is a 12-volt, maintenance-free wet-cell battery designed for lawn and garden tractors. It delivers 300 cold cranking amps (CCA) and 34 minutes of reserve capacity, making it a dependable starting battery for small-engine equipment. The flat top design and pre-charged, ready-to-install construction reduce service time at installation. The positive terminal is located on the left side when viewing the battery from the front, which is an important orientation detail for tractor cable routing. At 17 pounds, it is a standard U1 group-size battery suited for seasonal and year-round equipment use. A licensed technician or experienced equipment operator typically handles installation.
This battery is intended for residential and light commercial lawn and garden tractors, riding mowers, and similar small-engine equipment that requires a U1 group-size battery. The wet, charged configuration means no activation or acid filling is required before installation. The flat top terminal layout accommodates standard tractor battery cable connections without modification. It is appropriate for equipment serviced by small-engine technicians or power equipment dealers.
Designed as a U1 group-size replacement battery for lawn and garden tractors and riding mowers that specify a 12-volt U1 battery with a flat top terminal configuration.
Disconnect the negative cable first and reconnect it last to prevent accidental shorts during battery service.

Inspect the battery tray and hold-down hardware for corrosion or damage before installing the new unit. Follow equipment manufacturer guidelines and applicable safety codes when servicing electrical components on small-engine equipment.
