Description
A flat plate is thinner than a tubular one, so there is a larger active surface per unit of volume, and the cell delivers a high current in the first minutes of discharge. This mode is typical for a UPS that holds the load until a diesel generator starts, and for circuit breaker drives at substations. The low-antimony grid alloy reduces water decomposition, so topping up is needed once per 3 years. The cells are serviceable and require a ventilated room and racks with access to the vent plugs. The battery is assembled by connecting individual cells in series to the DC bus voltage or the UPS inverter input.
How to choose
The series is chosen by discharge duration. For discharges of minutes or tens of minutes at high current, SD/SDH suit better than tubular cells. If a longer life is needed, compare them with SGL/SGH, which last 25 years and have minimal water consumption. For frequent cycling in solar storage systems take LM/S per IEC 61427 from 150 Ah.

FAQ
How long do SD/SDH cells last?
The manufacturer states a service life of 15 years. It is reached with a correct float charging mode and topping up once per 3 years.
Which UPS are flooded cells with flat plates suitable for?
For industrial UPS with short high-power discharges, for example until a backup generator starts. The service life of such a battery is 15 years.
How often is an SD/SDH battery serviced?
Distilled water is added once per 3 years. Between topping ups the electrolyte level, cell voltage and the condition of connections are monitored.
What to take instead of SD/SDH if a longer service life is needed?
The same range has SGL/SGH with a Plante plate per DIN 40738, designed for 25 years of service.
Can SD/SDH be installed at oil and gas facilities?
Yes, oil and gas is directly included in the application field along with power engineering and industrial UPS. The ventilation requirements for the battery room at such facilities are checked separately.
