Common problems and causes of lithium batteries.
1. How to use the newly purchased lithium battery?
Discharge the battery with a small current (usually set to 1-2A), and then charge and discharge the battery 2-3 times with a current of 1A.
2. At the beginning of using the new battery, the voltage was unbalanced. After charging and discharging several times, it returned to normal. Why is this?
Although individual cells are well matched in battery packs, there may still be different individual differences in self discharge; At present, chargers on the market are equipped with a charging balance function, which can restore unbalanced lithium batteries when charged by the charger.
3. What are the requirements for the storage environment of lithium batteries?
It should be stored in a cool and dry environment at room temperature of 15-35 ℃ and ambient humidity of 65%.
4. How long can lithium batteries be used? What factors affect its service life?
Lithium batteries can generally be used about 100 times, and their lifespan is affected by temperature, charging and discharging, etc. It is also necessary to choose a model with appropriate power to avoid forced use of the battery under overload conditions.
5. Do new lithium batteries need to be activated? Does it matter if it's not activated?
Activation is required. The new battery is usually in a dormant state after more than 3 months from the factory to the user's hands. It is not advisable to immediately perform high-intensity discharge, otherwise it will affect the efficiency and lifespan of the battery.
6. What is the reason why the new battery cannot be charged?
The battery has zero charge, high internal resistance, and the charger mode is incorrect.
7. What does the C number of lithium batteries represent?
'C' is the symbol for battery capacity, which is the same as the symbol for current being 'I', while 'C number' represents the rate, which is the abbreviation for the current size of a battery based on its nominal capacity.
8. What is the optimal storage voltage for lithium batteries? What is the battery level?
The single voltage is between 3.70-3.90V, and generally, newly manufactured batteries carry 30-60% of the electricity.
9. What is the normal pressure difference between batteries? What if the pressure difference exceeds the rated value?
A new battery with a manufacturing date of one month has a voltage of approximately 30mV, which is 0.03V, which is normal. When the battery is left for more than 3 months, 100mV, or 0.1V, can be used. A battery pack that exceeds the rated voltage difference can be paired with an intelligent charger with balancing function for 2-3 cycles of low current (1A) charging and discharging.
