VMAX tanks are classified as non-spill able, non-hazardous, dry batteries making them NOT restricted for Surface, Maritime and Air Transport.Electrolyte Suspension systemVMAX tanks utilize an electrolyte suspension system consisting AGM (Absorbed Glass Matt) of a high porosity that totally absorb and contain the electrolyte. No silica gels or any other contaminants are used.Maintenance Free OperationThere is no need to check specific gravity of the electrolyte or add water to VMAXTANKS™ during float service life.Reliable, Rugged ConstructionThe extra strong ABS container reduces case bulging and plate warping, ensuring long life and high performance.Low Pressure Valve Regulated SystemAll VMAXTANKS™ are equipped with safety release valves, designed to operate between 0.98-196.1kpa and automatically reseal. Hence, there is never an excessive accumulation of gas within the battery.Heavy Duty Military Grade GridsHeavy duty lead tin alloy grids provide an extra margin of performance and service life in either float or cyclic applications, even after repeated over discharges.Cyclic Service LifeVMAX is known to deliver one of the highest numbers of discharge / recharge cycles. Depending on the use and average depth of discharge it can offer an average of:Number Of CyclesDepth of Discharge300100%60075%90050%150025%3500+10%Float Service LifeVMAXTANKS™ have an expected life span of 8 to 10 years in float service applications.Low Self DischargeThe self discharge rate of the new VMAX tanks at room temperature is approximately 1-2% of rated capacity per month (compared to 2-3% for most other AGM batteries and 15-20% for Lead Acid batteries).Operating TemperatureVMAXTANKS™ may be operated over a broad range of ambient temperatures.Ultra Low ResistanceVMAXTANKS™ Ultra Low Resistance make it up to 99% efficient (compared to 85-95% as in Lead Acid Batteries and 97% in most other GEL and AGM batteries).Higher Power DensityA special assembly technology is used to enhance power density to a considerable level.Don’t settle for an average Lead Acid Battery, upgrade to a VMAX CHARGE TANK premium AGM deep cycle battery
