When charging a long-unused or new battery, using fast charging at the beginning will affect the life of the battery. Therefore, this battery should be charged with a small current first, so that it meets certain charging conditions, this stage is called pre-charging.
The smart pulse repair charger is generally divided into three stages: constant current charging, constant voltage charging and floating charging.
In the constant current charging phase, the charger will charge the battery at the maximum current until the battery voltage is close to the charger output voltage.
Then enter the constant voltage charging stage, at this time the charger will keep the output voltage unchanged, the battery voltage will gradually rise until it reaches the highest voltage set by the charger.
Finally, it enters the floating charging stage, where the charger maintains the battery voltage at a low current to keep the battery fully charged. The whole charging process is intelligently controlled by the charger, which can effectively protect the battery charging safety and extend the battery life.
Smart pulse repair chargers usually include the following stages:
1. Startup stage: The charger starts to work, and detects whether the battery voltage is lower than the normal working range. If the battery voltage falls below the set value, the charger will activate the repair function.
2. Pulse repair stage: In this stage, the charger will enter the battery by sending a pulse signal of a specific frequency and amplitude to decompose and remove the sulfate crystals in the battery, thus repairing the performance of the battery.
3. Recovery stage: After the pulse repair is completed, the charger will be transferred to the recovery stage, and the battery will be charged to the appropriate voltage level through the normal charging mode.
4. Floating charge stage: When the battery reaches the set voltage level, the charger will be transferred to floating charge mode, providing a constant current to maintain the charge state of the battery. This stage keeps the battery charged while preventing overcharging.
5. Power off protection: If the battery is full or otherwise faulty, the charger will stop charging and protect the battery from overcharging or other adverse conditions.

It should be noted that different smart pulse repair chargers may have slightly different stages and functions, and please refer to the charger's manual for specific operating steps.
