Problems solved by technology
[0002] At present, in the process of charging lead-acid batteries, there are usually three stages of charging, that is, the initial constant current stage, the intermediate constant voltage stage, and the later trickle stage. When the current of the charging circuit in the constant voltage charging mode reaches the lamp current value, the charging circuit changes from the constant voltage charging mode to the trickle current mode. However, as the charging times of the lead-acid battery continue to increase, the constant voltage charging mode The time it takes for the current to reach the lamp current value will become longer and longer, which will cause the battery to be charged at a constant voltage for a long time, resulting in serious water loss of the battery, which will greatly reduce the service life of the battery

Embodiment Construction
[0016] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0017] The present invention provides a charger, including a controller 6, a charging circuit 1, a counting circuit 2, a storage circuit 3 and a comparison circuit 4, and the charging circuit 1 includes a constant voltage charging mode. The counting circuit 2 is used to record the charging times of the charging circuit 1, that is, the counting value of the counting circuit. The storage circuit 3 stores one or more preset count values, and according to each count value, the controller 6 controls the corresponding lamp turning current value in the constant voltage charging mode. The comparison circuit 4 is used to compare the count value of the count circuit 2 with the preset count value of the storage circuit 3 . When the counting value of the counting circuit 2 reaches the preset counting value of the storage circuit 3, the controller 6 sets a new lamp-turning...

technical field [0001] The invention relates to the field of accumulators. Background technique [0002] At present, in the process of charging lead-acid batteries, there are usually three stages of charging, that is, the initial constant current stage, the intermediate constant voltage stage, and the later trickle stage.
