VRLA Batteries at Lincon Batteries
VRLA stands for Valve-Regulated Lead-Acid and is the designation for low-maintenance lead-acid rechargeable batteries. Because of their construction, VRLA batteries do not require regular addition of water to the cells. VRLA batteries are commonly further classified as a Absorbent Glass Mat battery or Gel battery. These batteries are often called sealed lead-acid batteries, but they always include a safety pressure relief valve. As opposed to vented (also called flooded) batteries, a VRLA cannot spill its electrolyte if it is inverted.
Because VRLA batteries use much less electrolyte (battery acid) than traditional lead-acid batteries, they are also occasionally referred to as an "acid-starved" design. The name "valve regulated" does not wholly describe the technology; these are really "recombinant" batteries, which means that the oxygen evolved at the positive plates will largely recombine with the hydrogen ready to evolve on the negative plates, creating water—thus preventing water loss. The valve is strictly a safety feature in case the rate of hydrogen evolution becomes dangerously high.
One result of this design is a much higher ratio of power to "floor space" than large, flooded type battery systems; another is a high-rate power capacity, though of relatively short duration. As a result, VRLA batteries are frequently employed in UPS (uninterruptible power supply) or other high-rate applications. VRLA batteries can be substituted in virtually any flooded lead-acid battery application (in conjunction with well-regulated charging), as well as applications where traditional flooded batteries cannot be used, because of their unique features and benefits.
Summary of VRLA Battery Range
Our HDC series are AGM batteries that have been designed for cyclic applications, whilst maintaining all the added advantages of starved electrolyte” technology; fast charging, very low gassing, wide temperature range, , high capacity per mono bloc, can be operated in any orientation and is offering a design Life of up to 10 years at 20°C.
The SEC UK HGB Pure Gel Battery has design features such as true thixotropic gelled electrolyte to improve cycling capability, offering deep discharge operations, high number of cycles, up to 30 days discharge protection and can be used in any position with a wide temperature range. With a design life up to 10 Years the HGB Battery is of robust construction where the electrolyte is suspended within a Silicon Gel, this holds the lead plates firm under any shock and vibration conditions. The HGB Gel battery incorporates valve regulation technology giving high cyclic capability, deep discharge characteristics and deep discharge protection, therefore these Gel batteries are highly suited for cyclic applications, critical energy and high discharge applications. SECUK Gel batteries best operate between temperatures of -30°C to +45°C.
The Front Terminal HFTA Series are AGM technology batteries with a terminal configuration designed for racks and cabinets. Robust copper terminals located at the front of the battery providing high conductivity, easy installation and low maintenance. Thick pasted plates with high quality High Tin Calcium alloy grids provide long operation life, up to 12 Design Life, high rate discharge and fast recharge. Battery sizes are 12 volt ranging from 55 to 200 Ah and can be supplied in either ABS or Flame Retardant casing (V-0 casing upon request). Main application for this series includes Security, Telecommunications and Control Systems. These batteries operate between temperatures of -30°C to +45°C.
Lithium Phosphate Rechargeable batteries have characteristics that offer fast recharging, light weight mono blocs and battery solutions, wide operating temperature range, excellent cycling performance (up to 3000 cycles), low internal resistance, give high efficiency and a flat terminal voltage, therefore 100 % of the battery’s capacity can be accessed. Our LiFEPO4 HLPH battery can be fully charged under a wide temperature range, to the 100 % point in a matter of a couple of hours using the correct charger or Solar System. SEC UK can design bespoke battery pack solutions or standard mono bloc batteries to suit all specifications, whatever the voltages and capacity requirements are. Applications include off-grid solar and/or wind, Leisure Market; where fast recharge time is important. The LiFEPO4 has an initial high cost compared to traditional battery types, but compensated by longer service life, superior reliability and excellent efficiency.
The Lincon Gel battery offers reliable cold cranking (starting power) and maximum power supply with a superior cycling performance. The robust construction ensures the battery will continue to work through the most extreme conditions with a high resistance to vibration. The battery is exceptionally clean and safe to handle, with the battery acid fixed using Gel making the battery completely leak proof, allowing the battery to be put on its side. The Gel battery incorporates gas recombination technology, ensuring neither gas nor acid vapours are able to escape, making it completely maintenance free. The slow self-discharge rate of the battery plus its capability of recovery after deep discharge makes it ideally suited for seasonal or infrequent use.
The batteries in the Sonnenschein dryfit range are compact, versatile and can be used in a wide variety of applications. Dryfit technology consists of closed-system batteries in which the electrolyte is fixed in a gel. This means that no maintenance whatsoever is required throughout the entire service life of the battery. The special advantage of the Sonnenschein dryfit battery lies in the batteries’ suitability for extreme operating conditions and the highest demands on reliability.
The Sterling H, HP and HPX Series are the perfect replacements for many applications including: stand-by power, emergency lighting, phone systems as well as many others. These series utilise Sterling's unique electrolyte suspension system incorporating a microfiber glass mat to retain the maximum amount of electrolyte in the cells. The electrolyte is retained in the separator material and there is no free electrolyte to escape from the cells. The design of this series battery incorporates the very latest oxygen recombination technology to effectively control the generation of gas during normal use. Sterling's unique construction and sealing technique ensures no electrolyte leakage from case or terminals. The batteries are equipped with a simple, safe low pressure venting system which releases gas and automatically reseals should there be a build up of gas within the battery due to severe overcharge.
