What is battery internal resistance?
2025-03-21 11:14:38.835
It refers to the resistance to the current flowing through the battery when the battery is working. There are two parts: ohmic internal resistance and polarization internal resistance. Large internal resistance of the battery will cause the battery's discharge working voltage to decrease and shorten the discharge time. The internal resistance is mainly affected by the battery material, manufacturing process, battery structure and other factors. Is an important parameter to measure battery performance.
What is the harm of the battery heating?
2025-03-21 11:14:19.942
The battery is allowed to have a small amount of heat, whether in use or during charging, but abnormal heat is not allowed. The abnormal fever is obvious, and you can feel it by touching the battery case with your hand. Heat is very harmful to the battery. The heat first causes the electrolyte water to evaporate and gradually dry up, and then decreases the charging efficiency, deformation of the plates, increased internal resistance, accelerated oxidation of mechanical parts, burned out plates or separators, and finally manifests in reduced battery capacity and shortened life.
How to maintain the consistency of the battery pack?
2025-03-21 11:14:04.967
Although the lead-acid battery has been strictly selected when it leaves the factory, after a certain period of use, the non-uniformity will appear and gradually increase. The charger can't recognize or supplement the undercharge. How to balance the battery capacity? It must be performed by humans. The user measures the open circuit voltage of each battery periodically and irregularly during the middle and late periods of battery pack use. For lower voltages, recharge separately to make the voltage and capacity consistent with other batteries, and try to reduce their gap.
Can I do a partial replacement of my batteries?
2025-03-21 11:13:53.061
Partial battery replacement of lead acid battery banks is not recommended.
What is the danger if the connecting bolts are not tightened?
2025-03-21 11:13:38.066
A loose connection will cause the resistance at the connection to increase, which will easily cause sparks during charging and discharging. In severe cases, it will cause heat and fire, and an accident will occur.
