The Sway sealed lead-acid rechargeable battery (VRLA battery) is leak-proof and maintenance free. The Superiority of VRLA battery is derived from its uniquely efficient oxygen recombination technology. The oxygen evolved from the positive plates diffuses through the micro porous glass fiber mat to the negative plates where it is changed back to water by recombination reaction, eliminating the need for water addition .The result is a maintenance free battery.
[ No Free Acid ] All of the electrolytes are absorbed into the positive plates, negative plates, and the micro porous glass fiber mat. There is no free acid inside the battery, therefore the VRLA battery can be mounted in any location.
[ Safe and Sealed ] The unique construction and sealing technology ensure that no electrolyte leakage can occur from the terminals or cases of any VRLA batteries.
[ Maintenance-Free Operation ] During the expected service life, there is no need to check the specific gravity of electrolyte or to add water.
[ No Corrosive Gas Generation ] There is no corrosive gas generation during normal usage, as gas generation during over-charge is recombined in an unique "oxygen cycle".
[ Gas Pressure-Venting System ] VRLA batteries are equipped with a safe, low pressure venting system, which automatically releasing excess gas in the event that gas pressure rises to a level above the normal rate ensuring no excessive build-up of gas in the batteries. Resealing is automatic once the pressure is returned to normal.
[ Long Service Life ] The use of heavy-duty lead-calcium alloy grids with anti-corrosive construction enables the Sway VRLA Batteries to remain in float service about 5 years (6V, 12V series) and above 10 years (2V series), or expect between 250-1000 charge/discharge cycles depending on the average depth of discharge.
[ Long Shelf Life ] At an environmental temperature of 25íŠ(77oF), the self-discharge rate of VRLA batteries is only 3%(approx.) of rated capacity per month. Lower storage temperature enhances shelf life characteristics even further.
[ High Discharge Recovery ] Special separators, advanced plate composition, and a carefully balanced electrolyte system have greatly improved the ability of recovering from excessively deep discharge.
[ High Quality and High Reliability ] The Sway VRLA battery has stable and reliable capacity. It withstands overcharge, over discharge, vibration, and shock. Our batteries are 100% tested on line for voltage, capacity, and seals.
[ High Power Density ] Sway VRLA Batteries save installation space, while providing full and reliable power for the equipment, and many have been designed for high power output.
