The weight of your car battery may not be the first thing that comes to mind when thinking about your vehicle, but it plays a vital role in several aspects of your car’s performance and maintenance. In this article, we’ll dive into why car battery weight is important and the

In marine and vehicle systems, battery selection directly impacts performance and reliability. Deep cycle LiFePO4 (Lithium Iron Phosphate) batteries are favored for their long lifespan, high safety, and stable discharge characteristics. However, when considering their use in high-power applications such as engine cranking, windlass operation, or bow thrusters, factors like

Introduction: A Key Step in Energy Transition As the global climate crisis intensifies and renewable energy technologies advance, Solar-Plus-Storage systems are emerging as a core pillar of energy transition. These systems are not just tools for households and businesses to reduce electricity costs—they are essential for grid stability, energy independence,

1. What is Depth of Discharge (DOD)? Depth of Discharge (DOD) is a key metric used to measure the amount of energy discharged from a battery during use, typically expressed as a percentage. For example, a battery with a nominal capacity of 100Ah, when discharged by 80Ah, would have a

Supercapacitors, also known as ultracapacitors or electrochemical capacitors, are energy storage devices that bridge the gap between conventional capacitors and rechargeable batteries. They store and release energy quickly, making them ideal for applications requiring rapid charge and discharge cycles. Unlike batteries, which store energy through chemical reactions, supercapacitors store energy

The early gel lead-acid batteries developed by Sonnenschein (Germany) in the 1950s gained popularity in the 1970s. By mixing sulfuric acid with a silica gelling agent, the liquid electrolyte was transformed into a semi-solid paste, making the gel battery maintenance-free. In the early 1980s, AGM technology emerged, offering similar performance

AGM technology gained popularity in the early 1980s as a sealed lead-acid battery for military aircraft, vehicles, and UPS systems, aiming to reduce weight and enhance reliability. The sulfuric acid is absorbed by very fine glass fiber mats, making the battery spill-proof. This eliminates hazardous material transportation restrictions. The plates
