⚡ High Energy Batteries – 96% Revenue from Silver Zinc, 72% Drop in Quarterly Profit… Defence Contractor or Circus Act?
1. At a Glance
This 1979-born company supplies batteries to the Navy, Air Force, and DRDO. Sounds glamorous—“fueling India’s defence” and all that—but zoom in: 96% of revenue is from one product (Silver Zinc batteries), quarterly profit fell 73%, and working capital cycle is longer than a government file clearance. Market cap is ₹598 Cr, share price ₹667, and order book is ₹62.7 Cr—basically one Rafale invoice.
2. Introduction
High Energy Batteries (HEB) has a resume that reads like an ISRO brochure: batteries for aircrafts, torpedoes, missiles, submarines, and even strategic underwater one-shot units. It sells to DRDO, Navy, Air Force. In short, India’s military tech backbone depends on this small-cap company from Tamil Nadu.
The catch? The financials look like a DRDO missile test—one quarter successful, the next quarter dud. FY25 sales were just ₹77 Cr, PAT ₹13 Cr. Despite glamorous talk about fuel cells and vanadium flow batteries, the business is basically a single-product, single-customer defence supplier with high margins only when orders flow.
Think of it like this: every time the Navy buys a torpedo battery, HEB looks like a hero. When the Navy doesn’t, the quarterly profit vanishes faster than subsidy schemes in UP.
3. Business Model – WTF Do They Even Do?
Silver Zinc Batteries (96%): The bread, butter, and dosa of HEB. Used in torpedoes, aircrafts, submarines, and emergency systems. Revenue concentration risk? 100/100.
Nickel Cadmium Batteries (4%): For aircrafts, helicopters. Supplied to Mirage, Sukhoi, Chetak, AN-32. Marginal revenue share.
Lead Acid Batteries: Division shut since 2019. RIP.
R&D Bets:
Silver Zinc + Silver Chloride Magnesium batteries for DRDO torpedoes.
“One shot” batteries for Navy.
Exploration into hydrogen fuel cells + Vanadium Redox Flow Batteries. (Auditor note: R&D expense vs hype ratio = 1:10).
Question to readers: Would you trust a company with 96% dependence on one product to secure your national defence?

6. What’s Cooking – News, Triggers, Drama
Order Book: ₹62.7 Cr confirmed, with ₹101 Cr potential in 6 months. For a ₹77 Cr annual sales company, this is huge. Execution is spread over 12–18 months.
Exports: 15% revenues now from Malaysia, Italy, Philippines. First time exports are meaningful.
R&D programs: DRDO tie-ups for torpedo + missile batteries. If successful, will add recurring business.
