Flooded Lead Acid Batteries

U.S. Flooded Lead Acid Batteries

Handcrafted in the USA, U.S. Battery FLA deep cycle batteries utilize our exclusive XC2™ formulation and Diamond Plate Technology®, allowing them to reach peak capacity in fewer cycles, higher total energy delivery, and an extended battery life. The high charge efficiency design also meets new California Energy Commission regulations for combined charger/battery charge efficiency. And because of U.S. Battery’s unique design and variety of sizes in 2, 6, 8 and 12-volt applications, our FLA batteries offer the most compatibility with the wide range of chargers used in the field.

Xtreme Capacity2: Engineered to Perform

Xtreme Capacity

Prior to the introduction of synthetic TTBLS additives, the plate production process utilized a high temperature, high humidity curing process designed to achieve a relatively high percentage of TTBLS in the unformed plates. Even though this curing process was well controlled and produced consistently high levels of TTBLS, it was not well suited for controlling the size of the individual crystals that were ‘grown’ in the crystal development process. The resultant crystals varied widely in size and if the crystals grew too large, the plates were difficult to form and recharge and had lower capacity than those with smaller crystal sizes.

Through the addition of synthetic TTBLS with a uniformly fine crystal structure to the paste during mixing a smaller, more uniform TTBLS crystal structure is produced throughout the plate structure. This uniformly controlled TTBLS crystal structure results in the enhanced performance, charging and life characteristics of the U.S. Battery Xtreme Capacity Diamond Plates.

XC2 Advantage

Increased Initial Capacity
Synthetic TTBLS (tetrabasic lead sulfate) additive in the paste mix provides uniformly controlled crystal size of the resulting TTBLS in the cured plate and higher conversion efficiency of TTBLS to lead dioxide in the formed positive plate giving higher capacity.

Higher Peak Capacity
The same controlled TTBLS crystal size results in a higher conversion of TTBLS to lead dioxide in the cycled positive plate with greater and more uniform porosity and surface area for higher peak capacity.

Improved Energy Density and Specific Energy
Energy Since there is no increase in the size or weight of the battery, higher capacity translates to improved energy density (watt-hours/liter) and specific energy (watt-hours/kilogram).

Enhanced Recharge-ability
The more uniform crystal structure of the formed positive plate results in enhanced recharge-ability particularly at low temperature and from varying states of discharge.

Fortified Plate Construction – Improved Vibration and Shock Resistance
The more uniformly controlled TTBLS crystal size results in a stronger crystal network within the formed positive plate active material resulting in decreased shedding from vibration and shock.

Improved Life Cycle
The stronger crystal network within the formed positive plate active material also results in decreased shedding from deep cycling – the primary failure mode in deep cycle batteries.
