The mystery of the bulging lead-acid battery of electric bicycles, why it bulges, and what to do after it bulges

Before discussing the reasons for the bulging of lead-acid batteries in electric bicycles, our teachers must first understand what a lead-acid battery is. Lead-acid battery is the most commonly used secondary battery and is widely used in various fields due to its low price and mature technology application, especially for electric bicycles.ESS battery machine However, after using it for a period of time, many users will find that the battery management is bulging. why?

1. Lead-acid battery expansion

During the charging process of lead-acid batteries, if the charging current is too large or the charging time is too long, the gas inside the battery will be squeezed,Solid-state batteries causing the battery to expand.

Thermal expansion and contraction: In a high-temperature environment, the chemical activity inside the battery is too large,sodium ion battery which easily produces excessive gas and deforms the battery casing.

Battery aging: As the use time increases, the internal structure and chemical substances of the battery will gradually age, causing the battery performance to decline and easily bulge.

2.Coping methods

Control your own charging time: avoid charging for long periods of time, and strictly follow the recommendations in the battery manual for one charge.

Avoid use in hot environments: Try not to use or charge in hot environments, such as the summer sun.

Replace aging batteries in time: If the battery performance declines or is used for a long time, it should be replaced in time to avoid safety hazards.

So, do lithium-ion batteries expand?

The answer is: yes. Lead-acid batteries and lithium batteries are both chemical batteries, and a certain amount of gas is produced inside. Lithium batteries, in particular, can also develop bulges if they are improperly charged, overcharged, used improperly, or aged.

Therefore, for any type of battery, correct use and maintenance are crucial. Avoiding improper charging methods, preventing use in high-temperature working environments and timely replacement of aging batteries are keys to extending battery life and ensuring network security.

No matter which battery you use, safety always comes first. Once you notice a bulge on the battery, stop using it and replace it as soon as possible to ensure your safety and the safety of others.
