BatteryModel:PST7.5-12Size:151*65*94*100mmWeight:2.1kg1.
Container/Cover: Made of UL94HB and LU 94V-0 ABS Plastic2. Negative
Plates: Use the specialPbCa alloy grids, optimize therecombination
efficiency and less gassing.3. Separator: Import high quality AGM
separator.4. Positive Plates: PbCa grids minimize corrosion and
prolong life.5. Terminal post: Cooper material with maximum
conductivity, enhance thehigh current rapidly.6. Vent Valve: Allows
the release of excess gas automatically for
safety.ApplicationControl systems, Electric toys, Emergency lamp,
Power tools, Medical treatment equipment, Alarm system, Emergency
light system, Standby power supply, UPS and computer standby power
supply, Power system, Telecommunication system, Firefighting
equipment standby power supply, Railway station, Ship Equipment,
Telephone switching system.Operation and maintenance manualFor
maintenance free battery, it's free maintenance in the operation.
But we can only use it in proper operation to keep the long
lifetime of the battery,(1) Battery InstallationBatteries should be
installed possibly in a clean, cool, ventilated and dry place. The
battery should be placed upright. Each terminal between the
batteries is connected firmly.(2) The ambient temperatureAmbient
temperature is important factor for the battery operation. When the
ambient temperature is too high, Battery plate corrosion will be
increased, while absorbing more moisture; When the ambient
temperature is too low, the battery will not be full charged. All
this will affect the battery life. Therefore we suggest the working
ambient temperature is around 25 º C.(3) The charge and discharge
currentBattery charge and discharge current usually uses the
concept C, the actual value of C is related to the capacity of the
battery. For example, a 100AH battery: 1C = 100A. Charging current
is around0.1C; The charging current must not be bigger than 0.3C.
Discharge current general requirements in0.05 ~ 3C range.(4)
Charging voltageAfter the battery is full converted to float
charging, the float voltage is around 13.0V. If the charging
voltage is too high will cause the battery overcharge, otherwise
the battery will not be full charged. Charging voltage is abnormal,
it may be caused by the battery configuration error, or it may be
caused bycontroller failure. Do not choose the controller with bad
quality.(5) The depth of dischargeDepth of discharge of the battery
life is alsoa important factor for lifetime of battery, the deeper
the battery discharge, the fewer the number of cycles, so battery
should avoided from deep discharge.(6) Regular maintenanceBattery
should be regular checked in every period time after used, such as
check its outlook, measuring the average voltage of each battery,
etc. /* January 22, 2024 19:08:37 */!function(){function
