Why can't the battery be discharged sometimes during use?

The battery is discharged under the normal floating charge state, and the discharge time has not reached the requirement, the battery voltage on the program-controlled switch has dropped to its set value, and the discharge is in the terminated state. The reasons are: (1) The battery discharge current exceeds the rated current, resulting in insufficient discharge time, and the actual capacity is reached; (2) The actual floating charge voltage is insufficient during floating charge, which will cause the battery to be undercharged for a long time, and the battery capacity is insufficient, and may cause Batteries are sulphated; (3) The connection bar between the batteries is loose and the contact resistance is large, which causes a large voltage drop on the connection bar during discharge, and the voltage of the entire group of batteries drops quickly (the charging process is the opposite, and the battery voltage rises faster); (4) ) When the ambient temperature is too low during discharging, as the temperature decreases, the discharge capacity of the battery also decreases.
