Batteries Demystified by Ramesh Natarajan: Recent Episodes

Ramesh Natarajan

Mr. Ramesh Natarajan has over four decades of experience in the domain of lead acid battery designing, manufacturing, testing, marketing, and servicing with a special focus on trouble shooting peculiar problems. His continuing passion for learning about lead acid batteries and enthusiasm to share technical details related to batteries, chargers, and the various equipments which use batteries, has resulted in this venture, comprising of a series of Podcasts. His website www.RameshNatarajan.in also has Articles, FAQ's and Videos in addition to the contact details. Your comments and suggestions are most welcome.

In every process-oriented industry, we invest heavily in technology, automation, and quality systems.

Yet one of the biggest causes of quality issues often has nothing to do with machines or materials.

It is the gradual drift away from “Standard Operating Procedures” (SOPs)—often by the most experienced employees who believe they know a “better” or “faster” way.

Have you experienced situations where overconfidence or informal shortcuts compromised quality? How does your organization ensure that SOPs are consistently followed while still encouraging continuous improvement?

Having spent over 42 years in the lead-acid battery industry, I have witnessed how seemingly insignificant deviations from SOPs can eventually lead to inconsistent quality, increased warranty claims, higher manufacturing costs, and dissatisfied customers.

Experience is invaluable, but it should strengthen SOP compliance—not replace it.

In my latest podcast, I share why SOPs are much more than documents—they are the collective wisdom of an organization, built on years of experience, trials, failures, and continuous improvement.

I also discuss practical ways organizations can strengthen SOP compliance without discouraging innovation.

I would love to hear your thoughts on this topic.

How do we balance environmental responsibility with industrial competitiveness?

Because true sustainability is achieved not by making business difficult, but by creating regulations that reward compliance, encourage investment, and ensure a level playing field for every stakeholder.

The lead-acid battery industry has already demonstrated that a mature circular economy is possible. The lithium-ion industry is now building its own recycling ecosystem. Policymakers have a unique opportunity to learn from the strengths of both technologies and create regulations that accelerate sustainability without compromising industrial growth.

After all, the future of energy storage will not belong to a single battery chemistry. Different applications require different technologies, and each plays an important role in India's journey toward a cleaner and more sustainable future.

In this episode of my podcast, I share a real-life case study from a recent visit to the automotive battery industry.

A manufacturer was experiencing many warranty claims due to positive grid corrosion. To solve it, they strengthened the grid by adding extra horizontal and vertical wires.

The corrosion issue improved—but a new set of problems emerged.

Battery capacity reduced
OEM customers were unhappy with the heavier battery
Assembly processes had to be modified
Recharge time became longer

One solution had triggered a chain of unintended consequences.

When we stepped back and investigated the problem scientifically, we discovered that the real issue wasn't the grid design at all. The original corrosion problem was resolved—without redesigning the battery.

This experience reinforced a lesson that applies far beyond batteries:

Never treat the symptom before understanding the cause.

In engineering, and in life, solving one visible problem without identifying its root cause often creates several new ones.

A systematic, holistic approach almost always leads to a simpler, more effective, and more economical solution.

I hope this episode provides useful insights for professionals in battery manufacturing, quality, R&D, and process engineering.

I'd love to hear your thoughts:

Have you ever seen a "solution" create more problems than the original issue?

“Bolt it, or burn it?”

That’s the question I explored in my latest podcast episode.

Both bolt-on and weld-on cell traction batteries have their pros and cons — but the real difference shows up in:

How they’re serviced,
How they’re maintained, and
How long they last.

Most people think bolt-on cells are “better and convenient,” but do they realize the equalization step can make or break the battery’s life?

Listen in as I explain why ease of service doesn’t always mean better performance.

Bubbles on Pasted Plates… but why?

Everything looked normal.

•Same paste formula.

•Same raw materials.

•Same paste chemical additives

•Same machine settings.

But over 50% of the plates were getting rejected. Right after pasting. Before even reaching the drying oven.

The QC team tried everything—tweaking the mix, rechecking materials, and recalibrating equipment. Still, the problem persisted.

👉 Then came a phone call. And a video.

🔍 What followed was a surprising discovery

🎧 In this case study, I walk you through a puzzling situation from a battery factory floor where logic, observation, and fresh eyes led to a surprising yet straightforward fix.

Battery manufacturers specify the end-of-discharge voltage based on battery design and application.

Any discharge below the end of the discharge voltage is termed a deep discharge. Deep discharges, especially when more frequent, lead to battery capacity loss and degradation of the active material. Batteries subjected to deep discharges fail prematurely.

In the case of lead-acid batteries, deep discharges damage both the positive and negative electrodes.

Sporadic and infrequent low voltages for a short period caused by a high current drawn from the load cannot be considered deep discharge.

To understand the phenomenon of deep discharge, please tune in to this episode of my podcast, available on various streaming platforms.

Electric vehicles, or EVs as they are more popularly known, are a sunrise sector with a lot of government encouragement so that car buyers shift to EVs from Internal Combustion Engine vehicles. Internal Combustion Engine vehicles are referred to as ICE vehicles.

EV buyers are lured by the fuel cost savings that will accrue to them when they buy an EV.

However, any fuel cost savings accrued to an EV owner have to cover the

higher cost of EVs compared to ICE vehicles,
insurance premium riders,
high and probable maintenance expenses,
battery replacement cost,
roadside assistance charges, and
the extra cost of towing the car.

Regarding Total Cost of Ownership, the savings accrued after these expenses are covered can be considered real savings.

Operational savings accrued every month are, at best, an eyewash.

This podcast episode also dwells upon other issues, such as battery recycling and vehicle resale costs.

Another unmissable episode for all EV users, dealers, and battery manufacturers.

In today’s episode, I have a dear friend, Mr. Achim Lulsdorf, to discuss an important aspect of battery manufacturing.

Your response to the previous two episodes featuring Mr. Achim has been fantastic, and I’m sure you’ll benefit from listening to him today as well.

In a previous episode, I highlighted the importance of battery charging. That was in April 2023 ‘Secret Revealed – The Key To Long-Lasting Batteries’.

However, we’ve both realized that battery formation still doesn’t receive the attention it deserves from manufacturers. Many high-quality batteries perform poorly in the field or have a shortened lifespan due to neglect during the final stage-battery commissioning charge or initial charging.

Mr. Achim and I believe this critical aspect of battery manufacturing needs more focus and proper resources. We therefore decided to do this episode.

Mr. Achim has served as the CTO of Hammond Industries and the R&D Chief of Exide India. He is a busy international consultant, constantly traveling and often away from his base in the USA.

I love podcasting with him, but securing his time is difficult.

Mr. Achim has over 34 years of extensive experience in the field. I greatly admire his willingness to share his knowledge of lead-acid batteries.

Lead-acid batteries, a sustainable product, conforming to a circular economy are made using recycled lead.

All used batteries are collected as scrap for melting and smelting. These scrap batteries are recycled. They are smelted and refined. The refined lead is combined with other metals to be used again in the future.
The recovery of lead from scrap batteries is one of the major advantages that makes lead acid batteries economical and a favorite of the circular economy advocates.
All battery manufacturers including established large-scale industries use recycled lead to make alloys for the grid.
The lead oxide used as active material in the battery though made from pure lead, is in a majority of the cases obtained from recycled lead.
Some distributors & dealers of batteries misinform the battery user that their batteries contain pure lead and the competition uses recycled lead.

Stationary tubular plate lead acid batteries which pass the C10 test in the laboratory sometimes fail at site when used in solar photovoltaic applications. A lot of cases of batteries not getting recharged or not lasting out the long warranty of 5 years are reported.

The same design battery works well in a UPS application though the current drawn is higher, since UPS batteries are used generally for 3 to 5 hours despite being rated at the same C10 capacity.

Stationary batteries used for UPS as well as solar applications are both made with Tubular Positive plates and Pasted Negative plates. At times the operating specific gravities of electrolyte used, are also the same. As and when stationary batteries are made in SAN transparent containers, we observe that the recommended specific gravity of operation for both UPS as well as Solar Photovoltaic use is 1.240.

Why do the batteries fail in solar photovoltaic use?

In this episode of my podcast, I have outlined as to what needs to be done to make a good stationary battery for solar photovoltaic application.

आज के एपिसोड एक दिलचस्प केस स्टडी है।

पोडकास्ट की इस कड़ी में मैं एक ऐसे मामले के बारे में बात करने जा रहा हूं जो वाकई बहुत हैरान करने वाला था।

यह एक विचित्र मामला था जहां रैंडम लेड एसिड बैटरी के बैटरी विभाजक (separators) क्षतिग्रस्त हो रहे थे।

यह सभी बैटरियों में नहीं हो रहा था, इसलिए यह समझना बहुत मुश्किल था कि खराबी बैटरी विभाजक (separators) में थी या कुछ निर्माण प्रक्रिया दोष के कारण था।

आपको यह एपिसोड अंत तक सुनना होगा, .......यह समझने के लिए ..... कि separators के केवल कुछ बैटरियों में खराब होने का विचित्र कारण क्या था।

बैटरी वितरक (Battery Distributor) द्वारा रिपोर्ट की गई इस गलती के कारण वित्तीय नुकसान हुआ और वारंटी के दावे तब तक बढ़ते रहे ........ जब तक कोई समाधान नहीं मिल जाता।

यह ईमानदारी से एक आकस्मिक खोज थी ..... जिससे समस्या का समाधान हुआ।

जैसा कि मैंने पहले उल्लेख किया था कि यह एक आश्चर्यजनक खोज थी और इसलिए मैंने इस अनुभव को एक केस स्टडी के रूप में आपके साथ साझा करने के बारे में सोचा।

मुझे उम्मीद है कि आप इस प्रकरण से एक अलग दृष्टिकोण प्राप्त कर सकते हैं और मैं उन सभी लोगों को विशेष रूप से धन्यवाद देना चाहता हूं जो अपनी प्रतिक्रिया के साथ मुझसे जुड़ रहे हैं।
