Most people think a recharge cycle only happens when you drain the battery to 0% and charge it back to 100%. That's not quite right.

Used lithium batteries power everything from electric bikes to energy storage systems, and buying them second-hand can save a lot of money. But not every used lithium battery is safe or worth the price.

Even in 2025, if you search "batteries in refrigerator," you'll see millions of results and endless forum threads. The idea started decades ago when almost everyone used leaky alkaline or Ni-Cd rechargeable batteries.

Getting the time right in the plate charging bath is one of those steps that quietly decides whether your lead-acid batteries will deliver full capacity or fall short from day one.

A negative plate drying machine is specialized equipment used in lead-acid battery production lines. After the negative plates are pasted and cured, they still hold a lot of moisture. This machine removes that water quickly and evenly so the plates can move on to the next steps

Punching is the process where the tab shape is cut out from aluminum or nickel-coated copper foil, sometimes with an extra nickel tab welded on. If the punch is off by even 0.02 mm, the tab edge can have tiny burrs or tears

Grid casting machines are the equipment that produce the lead-alloy grids inside lead-acid batteries. These grids act as the skeleton that holds the active material and conducts electricity

In battery production, especially for lithium-ion types, an inert gas oven keeps things safe by using gases like nitrogen to block oxygen. This setup stops oxidation while drying electrodes or components. Workers often run into hiccups that slow down lines or hurt quality

In battery manufacturing, a screen printing machine uses a mesh screen to push ink or paste through, creating precise patterns on substrates like foil or paper

Lead-acid batteries power everything from cars to backup systems in factories. At the heart of making them is filling the cells with sulfuric acid, a step called acid filling. But what happens after that?

The core value of lead-acid batteries lies not only in their continued use as a mature product but also in the profound technical principles, engineering expertise, and deep understanding of energy storage system needs accumulated during their development

On October 31st, Better Technology Group Limited (Better Tech Group) has once again held its signature Point-to-Gift—a warm gathering tradition, which has distributed over ten thousand rewards to staff members.
