Charge input from solar arrays sometimes is insufficient to keep the batteries fully charged. During sun-less days, batteries are discharged but not charged. These conditions result in battery operating in Partial State of Charge (PSOC), Cycling and Deep-cycling. Also, solar systems are installed in open atmosphere exposing the batteries to extreme temperatures. Other lead acid batteries fail in such conditions due to sulphation, stratification, corrosion and plate shedding. Moreover, remote solar installations make water top-up difficult and costs money. To meet such rigors of usage HBL introduces a maintenance free (no water top-up) Tubular Gel VRLA battery with unbeatable combination of Tubular plate and gelled electrolyte, which is a perfect fit for all solar applications.

Triumph - Tubular Gel VRLA battery offered by HBL is a thoroughly proven product, designed to meet the demanding needs of many diverse applications. These batteries are technologically advanced and are ideal for regular cycling and deep discharge requirements of Telecom BTS sites. These batteries offer excellent cycle life (much higher than Flat plate AGM VRLA batteries) and good performance under partial state of charge operation. Tubular Gel VRLA batteries are highly suitable for telecom BTS sites having unreliable grid power or sites without grid power. These batteries are maintenance free and do not require a temperature controlled environment. This allows the network operator to save significantly on energy costs (OPEX) that will be incurred in cooling a network site. These batteries also offer a faster recharge capability to save on diesel generator running time after deep discharge cycles - further cutting down on fuel cost (OPEX) and thus lowering the payback period.

HBL’s Battle Ready batteries employ Pure Lead Thin plate technology for high performance. These Valve Regulated Lead Acid, maintenance free batteries are designed using Absorbent Glass Mat (AGM) separators. The use of AGM separators in combination with self-resealing, pressure-regulating valves and a starved electrolyte design enables recombination of gasses generated during normal operation. This eliminates free acid and the need for electrolyte top-up. These batteries are tested for vibration & shocks. Battle Ready batteries are delivered fully charged and are ready for use.

The Pure Lead-Tin VRLA battery has an unmatched peak power performance due to its thin plate design. This is a sealed maintenance free battery with no topping up required for life.The sophisticated SMPS battery charger with in-built protection ensures optimum charging of the batteries always. The periodic running of the Genset to charge the battery is therefore eliminated.

HBL's Nickel Cadmium Pocket Plate Battery designs are based on the superior Pocket Plate technology. The first electrode design for Nickel Cadmium Batteries employed the pocket plate construction which is still considered to be the most reliable design. The fully integrated modern factory, supported by strong process management and quality controls makes HBL one of the best Nickel Cadmium Battery production facilities in the world. In HBL’s Pocket Plate design, the active materials are encapsulated between folded steel strips which are perforated from both sides. This double perforation method increases the effective surface area by 30% and helps in better utilization of the active material thereby making the battery more efficient. The batteries are manufactured in 3 series designated as H, M and L based on their performance capabilities. The H series have thin plates to provide for high discharge currents, the L series have thick plates to provide lower currents for long durations and the M series have an optimized plate thickness which is ideal for medium discharge performance and durations. These Batteries are available as Single cells of 1.2V or in Blocks (individual cells thermally welded and connected either in series or in parallel) of higher voltages (2.4, 3.6V etc) and capacities.
