12V 33ah Gel Battery for Electric Power
SRG33-12
Gel series batteries are designed to meet the requirements of frequent cyclic and high temperature applications. Such as broadband, PVs etc through up-to-date gel technologies. Our gel batteries uses German origin high purity fumed silica to form sulfuric acid thixotropic Gel and fills to the batteries with vacuum to ensure the fully penetration of electrolyte through separators and plates pastes.
Battery Structure
1. Container/Cover: Made of UL94HB and LU 94V-0 ABS Plastic
2. Negative Plates: Use the special PbCa alloy grids, optimize the recombination 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 the high current rapidly.
6. Vent Valve: Allows the release of excess gas automatically for safety.
Application
UPS, Broadband, Electric powered vehicles, Electric powered toys, Vacuum cleaners, Medical Equipments, Goof cars and buggies, Wheel chairs, PVs, solar systems, control systems, power systems, wind energy systems, telecommunication /communication systems & etc.
Characteristics
Gel condition: The effect of sealed reaction is over 99.9%.
Minor self-discharge.
Low rate of loss of coolant.
Long service life.
Good deep charge cycle performance.
Good over-discharging recovery performance.
Widely working environment.

Operation and maintenance manual
For 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 Installation
Batteries 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 temperature
Ambient 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 current
Battery 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 around 0.1C; The charging current must not be bigger than 0.3C. Discharge current general requirements in 0.05 ~ 3C range.
(4) Charging voltage
After 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 by controller failure. Do not choose the controller with bad quality.
(5) The depth of discharge
Depth of discharge of the battery life is also a 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 maintenance
Battery should be regular checked in every period time after used, such as check its outlook, measuring the average voltage of each battery, etc.
