Battery course

At low temperatures, the chemical reactions inside the battery slow down, reducing its ability to deliver power. Additionally, the resistance in the battery increases, meaning more energy is required to make the electrons flow.

AGM (Absorbed Glass Mat)-batteries have several advantages compared to traditional lead-acid batteries:

• They require less maintenance than vented lead-acid batteries, as they do not need water refills.
• AGM batteries are less prone to acid leakage since the electrolyte is absorbed in the glass mat.
• hey have a faster charging time and can handle higher currents during both charging and discharging.
• AGM batteries withstand vibrations and shocks better than regular vented lead-acid batteries, making them ideal for use in boats, cars, and other vehicles.

• Explosion: Lead-acid batteries can produce hydrogen gas during charging, which can explode if ignited. Lithium-ion batteries can also explode if they are overcharged or short-circuited.
• Acid leakage: Lead-acid batteries contain sulfuric acid, which is highly corrosive and can cause severe chemical burns if it leaks.
• Electric shock: Incorrect handling, such as connecting the terminals incorrectly, can lead to electric shock or short circuits..
• Fire hazard: Overheating or improper use of lithium-ion batteries can lead to fires.

Thermal runaway is a dangerous situation where a battery overheats uncontrollably. This occurs when a cell in the battery becomes too hot, either due to overcharging, a short circuit, or physical damage. The high heat can cause the electrolyte in the battery to break down and release more heat, potentially triggering a chain reaction in other cells within the battery. The result can be a rapid increase in temperature, gas leakage, fire, or explosion. This is particularly hazardous in lithium-ion batteries, which have high energy density.
