1.What does it mean when a battery is "starved"?
Spin Force: If a battery is not charged for a long time, the battery plates will undergo irreversible sulfation, which can cause the battery to malfunction. The main symptom of plate sulfation is that the voltage rises rapidly during charging, gas is released prematurely, the temperature rises quickly, and the voltage drops rapidly and the capacity is small during discharge, meaning that it cannot be charged at all, or even if a little charge is added, the electricity will be exhausted very quickly.
2. How can we prevent the battery from "starving" after being left unused?
Shunli: Lithium batteries need to be charged and maintained regularly. If the electric vehicle is not used for a long time, batteries with protective plates and placed in electrical appliances should be charged once every 2-3 months, for 2 hours each time, to maintain the activity of the lithium battery. Additionally, the battery main switch should be disconnected, or the battery plug should be unplugged, because apart from the battery‘s self-discharge, the components such as the controller and others placed nearby will also consume power. This way, the battery can be protected to the greatest extent and its service life can be extended.
3. When the battery is in a state of "starvation" due to low power, how should it be dealt with promptly?
① Small current activation method. Use professional equipment to perform small current activation. The activation time is 10-20 minutes. If activation fails, disassemble the battery to analyze the cause.
② Cleaning method For batteries that are not severely "starved", use a clean eraser to gently wipe the metal contact surfaces between the battery and the equipment. After long-term use, the metal surface of the battery has a certain degree of oxidation, which causes poor contact and shortens the battery‘s usage time. Using an eraser can remove the oxide layer on the surface, making the contact between the battery and the equipment better.
