81. Stop Losing Power: The Connection Mistake Most Forklift Users Make (00:07:29)
“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, andHow 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. SHARE YOU...

79. Bubbles on pasted plates – Why? A case study. (00:05:59)
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 thi...
78. Deep Discharge Of Lead-Acid Batteries Explained (00:07:47)
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 volt...
77. Are EVs Fitted With Lithium-Ion Batteries The Future Of Passenger Transportation? (00:31:24)
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 premi...
Did you know that Lithium-Ion batteries are not similar to lead-acid batteries in terms of safety and handling procedures?

72. Necessity Of Using Dry Charged Plates To Make Good SMF Batteries (00:10:43)
The manufacture of SMF batteries is not as easy as that of flooded electrolyte vented type batteries. One main reason for this is that an SMF battery has limited electrolyte, and the specific gravity of this electrolyte cannot be measured. Is there a way to ensure the required consistent specific gravity in all the cells while maintaining a constant volume of sulphuric acid? How can a good SMF battery be manufactured? To learn how to make long-life, high-performance SMF batteries, pleas...

60. Battery regeneration: a fashionable trend or workable model? (00:10:50)
✳️ Is it practically possible or economically viable? ✳️ ▶️ When a battery stops performing well or even fails within its warranty period, it must be thoroughly checked before being scrapped. ▶️ As a battery ages, its performance naturally declines—much like the human body. ▶️ Speaking of which, here's a helpful analogy: think of your body with all its organs. As we age, our organs wear down over time. Some of them deteriorate gradually, while others may completely fail. ▶️ ...
