Description
The range consists of SLR500 and SLR1000, the capacities are given for a 10-hour discharge, and for SLR1000-2 1000 Ah at 20 hours is also given. At a deeper discharge of up to 70 % DoD the cycle life is 5000 cycles, i.e. the difference from 50 % is small and the battery can be operated on most of its capacity. According to the manufacturer, the design combines silica gel and AGM, and the negative plate contains nanocarbon. The cells are installed horizontally, so the rack is designed for the lying position. The weight is 34 kg for SLR500 and 67 kg for SLR1000, which is taken into account when calculating the load on the floor and the rack. A battery of the required voltage is assembled by connecting 2 V cells in series.
How to choose
The model is chosen by the energy to be stored and the permissible depth of discharge. With the same number of cells, SLR1000 gives twice the capacity, but weighs 67 kg versus 34 kg. For standby backup without daily cycles, the 2 V EN320-2, EN480-2 or EN540-2 with the EUROBAT class 12+ years are suitable. For small 12 V systems with a capacity up to 238 Ah, FXH monoblocks are more convenient.

FAQ
How many cycles does SLR1000 withstand?
The cycle life is 5500 cycles at 50 % DoD and 5000 cycles at 70 % DoD.
What is the weight of SLR cells?
SLR500 weighs 34 kg, SLR1000 weighs 67 kg. The rack and the floor are calculated taking this weight into account.
How should SLR cells be installed?
The specification provides for horizontal installation of the 2 V cells, so the rack and connecting links are selected for the lying position.
What systems are SLR cells suitable for?
For solar systems, energy storage units, UPS systems and telecom with heavy cyclic mode, where the battery is discharged every day.
What is the SLR capacity at a 10-hour discharge?
SLR500 has 500 Ah, SLR1000 has 1000 Ah at a 10-hour discharge and a cell voltage of 2 V.
