A mobile network is only as awake as its batteries. Every call, every payment, every one-time password rides through a tower site that must never sleep — fed, in much of the world, by a grid that sometimes does. The industry has stopped treating this as a diesel problem: in May 2026, one of India’s … Read more
Customers have started asking us whether the lead-acid starter batteries on their diesel locomotives can be swapped for lithium-ion — and the honest engineering answer is: not for the cranking duty, not as a drop-in, and not yet. This is not chemistry tribalism. We have published an honest guide to lithium-ion and a fire-safety review … Read more
India has all but finished wiring its railway — and the humble battery has never mattered more to it. By Indian Railways’ own figures published this year, 99.6 per cent of the broad-gauge network is electrified as of May 2026: 70,002 of 70,271 route kilometres under the wire, with just 269 kilometres to go. You … Read more
The metal that decides how long your battery lives is one most buyers have never priced. Antimony is a brittle, silvery element that lead-acid battery makers have alloyed into their plates since the earliest days of the industry — a few quiet per cent, hidden inside the casting. For most of a century it was … Read more
An electric car’s battery retires with most of its life savings still in the vault. The industry convention is that an EV pack comes out of the car at around 70 to 80% of its original capacity — not because it has stopped working, but because a car is an unforgiving employer: range has shrunk, … Read more
The cheapest battery on the comparison sheet is rarely the cheapest battery you will own. Purchase price is one line of a long invoice. The rest arrives quietly, over years: in the electricity the battery wastes, the hours a technician spends on it, the cooling its room demands, the shift it fails to power, and … Read more
Hydrogen is energy’s most seductive storage idea — and physics has been quietly returning the same verdict on it for fifty years. Hydrogen is the most abundant element in the universe; feed it through a fuel cell and the exhaust is water vapour; a tank refills in minutes, like diesel, while a battery asks for … Read more
The lead-acid battery is more than a hundred and sixty years old, and it has just learned a genuinely new trick. Not a marketing trick — a materials one: put the right carbon in the negative plate, and the chemistry’s oldest weakness starts to give way. The result is called the lead-carbon battery, and it … Read more
This guide is written by a lead-acid battery maker, and we are naming that interest in the first sentence so you can hold us to the standard it demands. Scare stories about a rival chemistry would be cheap, and we will not sell them: lithium-ion cells power billions of phones, tools and vehicles through billions … Read more
The fastest way to charge a battery is to not charge it at all. Hand over the empty one, take a full one, drive off: battery swapping turns an hours-long chemistry problem into a two-minute logistics problem, and every few years the idea is announced as the future of electric transport. As of 2026 the … Read more
