Sealed batteries, like those in electric vehicles or energy storage systems, are designed to keep everything inside contained. Air leakage happens when the seal isn't perfect, allowing outside air to slip in or internal gases to escape.

People often lump all lithium-based batteries together, especially when hearing about fires or explosions in news stories.

Many motorcycle owners deal with batteries that die unexpectedly, especially after the bike sits for a few weeks. Slow cranking in the morning, dim headlights, or a complete failure to start can ruin a ride.

The starter battery, often called the starting battery or cranking battery, provides the initial burst of power to turn over your engine. Most vehicles use a 12V starter battery designed specifically for high cranking amps rather than deep cycling.

Battery plates are the heart of any lead-acid battery, whether it's powering a car starter, a forklift, or backup systems. These plates hold the active material that reacts with the electrolyte to store and release energy.

If you've noticed your car battery​ charge slow or not holding power as it should, you're dealing with a common issue that many drivers face.

The 2025 World Green Development Investment and Trade Expo & China Green Food Expo were successfully held in Nanchang, Jiangxi Province.

The name "18650" simply tells you the size: 18 mm in diameter and 65 mm long, with a round "0" shape. Inside is a lithium-ion chemistry that stores a lot of energy in a very small package.

Temperature is the single biggest factor that decides how long your lithium-ion batteries last, how safe they are, and how well they perform day to day. Get it wrong and you'll notice shorter runtime, faster aging, or in rare cases serious safety issues.

Swelling rarely happens for just one reason. Usually several factors work together. The good news is that almost all cases come from a handful of well-known triggers that are easy to avoid once you know them.
