High Perfomance Valve Regulated Lead Acid Battery
Silver Start Batteries For Aviation

Sealed Maintenance Free Lead Acid Aircraft batteries

HBL Power Systems Ltd. is a listed Indian company, in business since 1977, with a focus on engineered products and services. Our initial business strategy was to identify technology gaps in India that the company could fill by 'indigenous efforts'.:

Nickel Cadmium aircraft batteries, developed for the Ministry of Defence, were among the first products of the company. Subsequently, Silver Zinc aircraft batteries and Sealed Lead Acid aircraft batteries [SILVER START] were added to extend the range and offer a wider choice for our customers.

Silver Start on-board aircraft batteries employ Pure Lead-Tin, Thin Plate technology for high-performance. These Valve Regulated Lead Acid (VRLA) batteries are designed using Absorbent Glass Mat (AGM) separators that render the batteries spill-proof for aerobatic use. The use of AGM separators in combination with self-resealing, pressureregulating valves and a starved electrolyte design enable recombination of gases generated during normal operation. This eliminates the need for electrolyte top-up.

Silver Start batteries are delivered fully charged and are ready for immediate use. These batteries are a replacement for the Russian 12CAM28 dry charged lead acid battery.

Our success has been built serving some of the world's most demanding customers and we would welcome an opportunity to serve your business too.
