For more than 114 years, the exclusive tubular positive plate technology in Enersys diesel starting batteries has consistently delivered high-rate performance.

The basic design has remained the same for the last eighty plus years, making this square tubular postive plate the world standard and nationwide Enersys exclusive. As a result, the NRS line of  low maintenance diesel locomotive starting batteries can be found on most locomotives today.

TubularPositivePlatesImageTUBULAR POSITIVE PLATES
Batteries rely on a chemical reaction between active materials and electrolyte to produce voltage and current. Enersys’ exclusive square tubular positive plate design provides 60% greater surface area for holding active material and exposing it to electrolyte than conventional flat plate batteries, Enersys’ exclusive square tubular positive plate design provides 60% greater surface area for holding active material and exposing it to electrolyte. The result ois improved high rate performance.

LONGER LIFE
The Enersys diesel cranking line offers 75% longer battery life because the positive conducting spines are surrounded by active material, protecting them from corrosion. Our heavy duty negative grid structure keeps negative active material in place during the rigors of shock, vibration, and deep and heavy discharges. The benefits are longer life and higher capacity, both in ambient and low temperature service.

sleeve-separatorsSLEEVE SEPARATORS
Our sleeve separators promote the free flow of electrolyte around positive and negative plates to help ensure constant load performance. The sleeve design eliminates moss shorts across positive and negative
plates and problems due to missing or misaligned separators, the number one cause of premature battery failure.

LMUDMORE POWER
Copper-core intercell connectors and terminals reduce electrical resistance and provide greater sustained starting power. Enersys’ improved state-of-the-art element design provides 10% more cranking power at lower temperatures.

Enersys’ LMUD-725 provides the highest power output of any locomotive starting battery in the industry. With Capacities from 280 to 725 A.H., we’ve got the power you need.

HEAT BONDED TOP
Maintenance requirements are further reduced with a tough tray material, unique heat seal top, and safety insulated dead top. Heat sealing the cell cover to the jar creates a permanent seal with a lifetime guarantee. Resealing is not required, and electrolyte creepage, corrosion buildup and loss of power from electrolyte dilution are also eliminated.

ReducedMaintenanceCostsREDUCED MAINTENANCE COSTS
Metallurgical improvements in positive plate metal and greater electrolyte reserve guarantee watering just once a year (@77oF,2.3V/cell), versus four times a year. This results in at least a 75% reduction in labor costs for watering every year for every locomotive.

NATIONWIDE SERVICE
Enersys has a nation wide service network to provide you with quality service backup.

WARRANTY
The LMS has a three year full warranty and five years pro rata, for a total of eight years, against defects and workmanship. The LMUD has a 100% warranty for five years against defects and workmanship. Warranty starts on the Ship Date.
