Description
The positive plates are tubular, cast from a low-antimony alloy, which reduces water consumption. Topping up is needed once per 3 years, which is a small workload for staff with serviceable cells. Besides DIN 40736, the series complies with DIN 40740 and IEC 60896-11, so it can be specified in projects where the customer requires confirmation under European and international norms. The cell capacity is higher than the minimum DIN values, so with the same case size the bank gives a larger backup time margin. The battery is assembled from individual cells on racks in a ventilated room, and the voltage is set by the number of cells for the DC bus.
How to choose
LM is taken for float operation, when the battery stands on float charge for years and is discharged only in an emergency. For frequent cycling in a solar power plant the cyclic version LM/S is better suited. If 25 years of service are needed, look at SGL/SGH, and for short powerful discharges of industrial UPS, SD/SDH with a 15-year term are more suitable.

FAQ
What is the service life of OPzS cells of the LM series?
The manufacturer states 20 years. For comparison, SGL/SGH are designed for 25 years and SD/SDH for 15 years.
How often should water be added to LM cells?
Topping up is needed once per 3 years. In between, the electrolyte level is checked during scheduled inspections.
Which standards do LM cells comply with?
The series is made per DIN 40736 and DIN 40740, and also complies with IEC 60896-11 for stationary vented batteries.
How does LM differ from LM/S?
LM is designed for float mode with a service life of 20 years, while LM/S is intended for frequent deep cycles in renewable energy storage systems.
Are OPzS LM cells suitable for railways?
Yes, railways are directly included in the application field together with telecom, power engineering and oil and gas. A service life of 20 years matches the long modernization cycles of such facilities.
