All VMAXTANKS AGM Batteries Feature:

Sealed Construction
The unique construction and sealing techniques of VMAX tanks guarantee leak-proof operation in any position with no adverse effect on capacity or service life. VMAX tanks are classified as non-spillable, non-hazardous, dry batteries, making them NOT restricted for Surface, maritime, or Air Transport.
Electrolyte Suspension system
VMAX tanks utilize an electrolyte suspension system consisting of AGM (Absorbed Glass Matt) of high porosity that totally absorbs and contains the electrolyte. No silica gels or other contaminants are used.
Maintenance Free Operation
During the float's service life, there is no need to check the electrolyte's specific gravity or add water to VMAXTANKS™.
Reliable, Rugged Construction
The extra strong ABS container reduces case bulging and plate warping, ensuring long life and high performance.
Low-Pressure Valve Regulated System
All VMAXTANKS™ are equipped with safety release valves, designed to operate between 0.98 and 196.1kpa and automatically reseal. Hence, there is never an excessive accumulation of gas within the battery.
Heavy Duty Military Grade Grids
Heavy-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 Life
VMAX 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 Cycles Depth of Discharge

300 100%

600 75%

900 50%

1500 25%

3500+ 10%
Float Service Life
VMAXTANKS™ has an expected life span of 8 to 10 years in float service applications.
Low Self Discharge
The new VMAX tanks' self-discharge rate 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 Temperature
VMAXTANKS™ may be operated over a broad range of ambient temperatures.
Ultra Low Resistance
VMAXTANKS™ Ultra Low Resistance makes 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 Density
A special assembly technology is used to enhance power density to a considerable level.
