1. lithium 12v battery charging.
Charging method.
The charger for charging a 12V lithium battery should conform to the characteristics of the three-stage charging of a lithium battery and need to have and complete three stages of pre-charging, constant current charging, and constant voltage charging. Therefore, the original 12V lithium battery charger is better. When the original charger is damaged, do not blindly buy other chargers to charge 12V lithium batteries.
Ambient temperature.
When charging a 12V lithium battery, the ambient temperature should not exceed 040 ℃.
Charging cut-off voltage.
The charging cut-off voltage of a 12V polymer lithium battery is 12.6V. The balanced charging mode is adopted to ensure that the voltage of the single cell does not exceed 4.2V.
Charging current.
If not urgent, can be rechargeable at 0.2C, the current generally can not exceed 1C.
2. 12V lithium battery discharge.
Ambient temperature.
The discharge state is the working state of the 12V lithium battery, and the required temperature is-20 ℃ and 60 ℃.
Discharge cut-off voltage.
The discharge cutoff voltage standard of a 12V polymer lithium battery is 8.25V. Some can be set to 9V.
Discharge current.
There are other types of 12V polymer lithium batteries, such as high current, large capacity and so on. Polymer lithium batteries capable of high-power discharge need to control the current within the range of product specifications.
Charging current.
If not urgent, can be rechargeable at 0.2C, the current generally can not exceed 1C.
3. 12V Li-ion batteries self-discharge.
12V lithium-ion batteries store 40% to 60% of their charge better, but of course, this is not always possible. For example, cell phones are usually used until the system prompts for a charge.12V Li-Ion batteries are also subject to self-discharge. Prolonged self-discharge can cause over-discharge, so you need to be prepared for the self-discharge of 12V lithium batteries.
Regular Charging.
Charge the 12V lithium battery regularly to keep the voltage between 10.8V and 11.7V. Li-ion batteries have no memory effect and can be charged at any time.
Make sure that the discharge cut-off voltage is not within the operating range. If the charge is low, you need to decisively stop using it and recharge the battery.
