Description
The Plante plate has a developed surface formed directly on pure lead, so the cell delivers high currents well and tolerates deep discharge. Water consumption is minimal; in float mode one topping up per 3 years is enough. For a serviceable battery this is a rare interval, which reduces the number of staff visits to remote substations. The cells are flooded and emit gas during charging, so the battery room must be ventilated according to the norms. The battery is assembled from individual cells on racks, and the required DC bus voltage is obtained by connecting them in series.
How to choose
The decision depends on service life and discharge mode. When 25 years on float with rare but deep discharges are needed, SGL/SGH come first on the list. If 15 years is enough and the discharges are short and powerful, consider SD/SDH with flat low-antimony plates. For daily deep cycling in a solar power plant, it is better to take LM/S per DIN 40736 from 150 Ah.

FAQ
What is the service life of SGL/SGH cells?
The manufacturer states a service life of 25 years. With correct float charging and topping up once per 3 years, the battery serves this term on float.
How often should water be added to GRoE cells?
In float mode one topping up per 3 years is enough. The electrolyte level is still checked during scheduled inspections.
What does the designation GRoE mean for batteries?
This is how DIN 40738 designates stationary cells with a Plante positive plate. The plate is made of pure lead and has a developed surface.
Do SGL/SGH withstand deep discharges?
Yes, the Plante plate tolerates deep discharges and high currents. For daily cycling in a solar power plant there is a separate LM/S series per IEC 61427.
How do SGL/SGH differ from SD/SDH?
SD/SDH have flat low-antimony plates and last 15 years, while SGL/SGH are built on the Plante plate and last 25 years. Topping up is needed once per 3 years in both series.
