AGM Lead Battery Solutions
Valve-regulated lead acid (VRLA) absorbent glass mat (AGM) batteries resemble standard flooded lead batteries. However, VRLA AGM batteries are better suited for particular applications due to their distinct design and construction properties. AGM batteries have thin fiberglass mats between the plates that absorb and immobilize the acid.
Unlike standard flooded lead batteries, AGM batteries do not require maintenance or electrolyte watering. By internally recombining gasses rather than venting them externally, AGM batteries offer a safer energy solution.

- Glass Paste Additive
One of our premium offerings is PA10-6 which is a microglass fiber additive used as a processing aid in lead battery assembly. PA10-6 is a microglass fiber additive that is used as a processing aid in lead battery assembly. It can also contribute to improving battery performance and life.
PA10-6 is a glass microfiber additive for the lead paste mix; it improves plate curing during processing. The glass fiber is engineered to disperse in the paste mix, improving structural and performance properties. It has a fiber diameter that corresponds well with the pore structure of the pasted plate and can be used in both AGM and flooded batteries.
PA10-6 is added to the negative or positive paste mix. It enables electrolyte access to the active mass & improves
- Processing (curing, drying, plate stability)
- Battery capacity
- Paste reinforcement
- Automotive crank
- Charge acceptance
Gel Lead Battery Solutions
Gel lead batteries have a valve-regulated lead acid (VLRA) design and resemble standard lead-acid batteries, but gel lead batteries have several distinguishing design and construction properties that make them a better fit for certain industrial applications. For instance, they have an electrolytic solution consisting of sulfuric acid and silica, which forms a gel-like substance. Due to the solution’s higher viscosity, gel lead batteries can operate similarly to their lead-acid battery counterparts but with reduced maintenance needs.
Hi-Sep™
Designed for premium flooded lead batteries and VRLA gel batteries, Hi-Sep™ battery separators are specialized separators designed with high porosity of at least 70% that improves ionic mobility, thus enhancing battery performance. It uses close to a non-leachate formula composed of synthetic fibers, glass fibers, binders, and inorganic fillers. This composition makes it an ideal replacement for separators made of PVC, PE, and phenolic resin.
Hi-Sep™ is among the only globally available VRLA gel separators available in different configurations, such as rolled goods, sleeves, leafs, and with or without glass mats. The rolled goods type allows battery manufacturers to boost their battery throughput.
Advantages of Hi-Sep™ include:
- Increased ionic mobility
- High-heat durability
- Prevention of dendritic shorts
- Low electrical resistance
- Lowest electrochemical oxidation in its class
- Low impurity levels

- Partial state of charge (PSOC) and deep cycle battery applications
- VRLA gel battery cycles in motive power
- Reserve power applications that have unpredictable use cycles
Flooded Lead Battery Solutions
Flooded lead batteries power an extensive range of automotive and industrial applications. Their name comes from the excess electrolyte fluid in the battery, which floods the plates so they are completely submerged. Flooded lead batteries can be more cost-effective with a low upfront cost when used in industrial trucks and other automotive applications. However, they need regular maintenance in industrial applications to achieve their longest potential lifespan.
