RE48V1200 Battery User Manual Unlike the traditional flooded type of lead acid batteries, valve-regulated lead acid (VRLA) batteries use an electrolysis of water from the electrolyte caused by overcharge. This generates oxygen (O2) gas on the positive plates and can be absorbed by the hydrogen (H2) gas on the negative plates. These gases are recombined and not expelled so water can be kept without loss. General Construction The main components of a VRLA battery are (+) positive and (-) negative plates, separator, container, middle cover, vent caps, safety valve, electrolyte, and terminals.

Safety Valve This is an explosion-proof relief valve that can help reduce pressure and is able to resist acid overflow. The open pressure of the safety valve is 0.1~0.3kgf/cm2. Whenever the internal pressure increases up to the preset limited value, this valve begins to act and will release excessive gas, and the valve automatically seals up to prevent the entrance of oxygen from the air into the cell. Container and Cover With the minimum level of oxygen index over UL 94- HB, the material used is flame retardant, shock proof, acid-resistant, has high mechanical strength, and resists oil organic solvent or oil-made product.

Permanent airtight sealing between the cover and the container will prevent the electrolyte, lead, and air from escaping. Electrolyte The electrolyte contains sulfuric acid specified under the standards of JIS K 1321. The electrolyte is absorbed by a micro-porous separator without any fluid liquid present internally. Therefore, it is immobilized, leak-proof, and can prevent stratification or dry out. Terminals Both the positive or negative poles are made of lead-electroplated pure copper which can resist acid and corrosion. The plate group is connected to the post by soldering.

Both the post and the connectors are acid resistant and anti-corrosive for the battery to provide longer service life. Separator The Absorbent Glass Mat (AGM) separator functions as an electrolyte retainer and offers a high oxygen recombination efficiency, low internal resistance, and is free from producing exotic organic materials. Its surface area is sufficient to cover the plate. Plates Both positive and negative plates consist of the grid and the paste attached to it.

The grid of the CSB VRLA is made of lead calcium (Pb-Ca) alloy with superior mechanical properties, and the active materials of the paste consist of lead oxide (PbO), sulphuric acid and other materials that can enhance battery performance. 11F, No. 150, Sec. 4, Chengde Rd., Shilin Dist., Taipei City 111052, Taiwan (R.O.C.)

RE48V1200 Battery User Manual **ATTENTION** CAREFULLY READ THIS DOCUMENT SECTION. VRLA batteries are potentially dangerous and proper precautions must be observed in handling and installation. CSB recommends only knowledgeable and trained personnel can be qualified to work on batteries with proper tools and protective equipment. Keep unauthorized personnel away from the batteries during the maintenance activities. Any deviation from not following these safety guidelines can result in serious injury or death. Prior to handling batteries on a metal rack/cabinet, assure batteries are not inadvertently grounded by observing the ground fault detecting indicator.

Do not use the VRLA batteries at a site that can get moist or immersed in water. Doing so can cause the battery’s terminals to corrode, and/or cause electrical shock or fire. Do not use any dry fabric or other materials to clean the battery that could cause static electricity. Always use a damp cloth that has had the moisture wrung out of it. As appropriate, use an insulating blanket to cover exposed portions of the battery system when performing extended maintenance that could result in personal or equipment contact with the energized conductors. Certain types of rectifier circuits used in charging the VRLA battery may not include a line-isolating transformer.

In these cases, extreme caution must be exercised when maintaining and collecting data on the battery system. VRLA batteries are sometimes enclosed in cabinets with very limited access. Again, extreme caution must be exercised when maintaining and collecting measurements on the battery system. Always use the proper charger and the charging regulations set by CSB. Not following CSB guidelines and procedures, or using non- approved charging procedures, can cause the battery to leak acid, heat up, or cause a destructive fire.

Always Wear Eye Protection Prevent Electrical Shock No Open Flames Around Batteries Hazardous Chemicals Present Batteries Can Explode Always Recycle, Do Not Throw into Trash Electrical Hazards Battery system presents a risk of electrical shock and high current short circuit. The following precautions must be observed when handling CSB VRLA batteries: Store all batteries beyond the reach of children. Remove all personal metal objects from your person (watches, rings, etc.). Use insulated tools and gloves. Never clean battery terminals with wire brush Wear full eye protection and rubber gloves. Observe circuit polarities. Do not make or break live circuits.

Do not lay metal tools on top of batteries. All connection cables should be well insulated and not able to short electrically. If the cables do cause an electrical short, that may cause smoke or the battery to cause a large destructive fire. 11F, No. 150, Sec. 4, Chengde Rd., Shilin Dist., Taipei City 111052, Taiwan (R.O.C.)

RE48V1200 Battery User Manual Fire, Explosion, and Heat Hazards VRLA batteries can contain an explosive mixture of hydrogen gas which can vent under overcharging conditions. Do not smoke, introduce an open flame, spark, or extreme heat in the vicinity of the battery. Do not burn the battery or throw it into a fire. Doing so may cause the battery to explode and toxic gas to be released. Prior to handling the battery, touch a grounded metal object, such as the rack, to dissipate any static charge that may have developed on the operator’s body. Do not charge, discharge, or store batteries in a sealed container.

The individual battery should have 5 to 10mm of space between them to allow for proper cooling. If contained, assure the container, cabinet or room has adequate ventilation to prevent and accumulation of potentially vented gas. Never use the VRLA battery together with other types of batteries, such as dry cells and nickel- cadmium batteries. Doing so can cause explosions, fires, or bodily injury. When the battery approaches the end of its life, its performance will decrease very fast. The internal exhausted electrolyte and the corrosion of the positive plate may cause a failure.

If the battery continues in operation under these conditions, there could be extreme heat, leaking of even explosion. If there is any corrosion, cracking, deformation, heat generation, or other abnormalities to the VRLA battery upon its first use after purchase, do not use it. Please call the location where it was purchased. Using the battery with an abnormality can cause the battery to leak fluid, generate heat or explode. Battery Chemical Hazards Any gelled or liquid emissions from a VRLA battery is electrolyte which contains diluted sulfuric acid that is harmful to the skin and eyes. The electrolyte is also electrically conductive and corrosive.

If the electrolyte contacts the skin, wash the area immediately and thoroughly with water. If electrolyte enters the eyes, wash eyes thoroughly for a 10-minute period with clear water or a special neutralizing eye wash solution and seek immediate medical attention. Neutralize any spilled electrolyte with the special solution contained in a “spill kit” or with a solution of 1 pound of bicarbonate of soda to 1 gallon of water. Do not disassemble, reassemble, or destroy the battery. Doing so could cause the acid inside the battery to leak and cause severe burns or other accidents. Battery Recycling and Disposal VRLA batteries are to be recycled. Batteries contain lead and dilute sulfuric acid.

Dispose of the battery in accordance with local regulations. Do not dispose of the battery in a landfill, lake, or other unauthorized location. 11F, No. 150, Sec. 4, Chengde Rd., Shilin Dist., Taipei City 111052, Taiwan (R.O.C.) W W W . C S B - B A T T E RY .
