Design:
Positive electrode: tubular - plate with a polyester gauntlet and solid grids in a corrosion-resistant PbCaSn - alloy.
Charging:
Charging time up to 90%: 6h with 1,5·I10 initial current, 2.25 V/cell, 50% C10 discharged.
Discharge characteristics:
Deep discharges: more than 80% DOD or discharges beyond final discharge voltages (dependent on discharge current) have to be avoided.
Maintenance:
Every 6 months: check and record battery voltage, pilot cell voltage and temperature.
Every 12 months: check and record battery, cell voltages and temperatures.
Operational data:
Classification according to EUROBAT: > 12 years, Long life.
