200AH battery, the best charging current 20A, charging time of about 15 hours.
The following methods are generally available for calculating the charging time of rechargeable batteries:
Charging time (hours) = rechargeable battery capacity (Ah)\/charging current (A) * Coefficient of 1.5.
200Ah rechargeable battery, charging with 20A current, the charging time is :200\/20*1.5=15 hours (note: this method does not apply to newly purchased or long-term unused rechargeable batteries).
Extended information:

Charging should be carried out in one of the following situations:
The specific gravity of the electrolyte is reduced to below 1.2, the discharge is more than 25% in winter, and the discharge is more than 50% in summer. Dim lights start weak.
Some owners believe that fast charging can save time and only takes 3-5 hours. In fact, fast charging only quickly activates the surface of the battery, and in fact the battery is not fully charged inside.
In addition to fast charging, there is a slow charging, the charging time is 10-15 hours, those deep deficit batteries must be slow charging, otherwise the charging time is not enough, the charging amount is insufficient, will directly affect the driving performance of the car.
While charging is a fairly simple operation, there are some caveats:
1. Wear protective clothing when charging the lead-acid battery.
2. When charging, there can be no sparks near the battery, and smoking is prohibited.
3. When charging one or more batteries in parallel, the charger voltage should not exceed 16V.
