Description
OPzV Series Battery
The OPzV series batteries are the newly products which were developed in middle of 2006. The performances meet the standard DIN40742
Characteristics
Gelled electrolyte, no flow, no leakage or no gradation of sulfuric acid.
The positive plate is tubular plate, which can effectively prevent the active materials from falling off.
PVC-SiO separator, which is special for gel battery with tiny holes. The separator has high volume porosity, low electrical resistance and excellent wettability
Maintenance-free during the whole service life. Low self discharge rate
Proof against deep discharge according to DIN 43539 T5
Applications
Telecommunication equipment
Electronic instruments
Fire alarm and security devices
UPS power supply Solar power system Wind power system
