18650 lithium battery 3.7 v.How much is left after charging a ternary lithium battery 3000 times

release time:2024-03-04 Hits:     Popular:AG11 battery

  

  After charging a ternary lithium battery 3000 times, how many points are still 40% left

  1. About 40% of the electricity is still available.

  2. Typically, ternary lithium batteries have a nominal voltage of 3.7V, a charging cutoff voltage of 4.2V, and a termination discharge voltage of 2.75V.

  2. The range where the discharge voltage of a battery changes slowly is generally between 3.2 and 4.1. When discharged to a nominal voltage of 3.7V, most batteries still have more than 60 remaining electricity. Based on this estimate, there is approximately 40% remaining electricity at 3.5V.

  4. The discharge curve of each battery or type of battery is different, making it difficult to determine the remaining power based on the remaining voltage. Some software can display more accurate remaining power because the software has completed a complete discharge process, recorded the corresponding discharge data, and then calculated it based on the existing discharge data, making it more accurate.
