The total time to charge a lead acid battery can range from 12 to 18 hours, depending on the charging stage.
Charging a lead acid battery involves two main phases, according to referenced information:
- Constant-Current Charge: This initial phase brings the battery to approximately 70% of its full capacity, taking around 5–8 hours.
- Topping Charge: The remaining 30% is filled during this slower charge, which can last an additional 7–10 hours. This phase is crucial for the battery's long-term health.
This is summarized in the following table:
| Charge Phase | Percentage Charged | Duration | Importance |
|---|---|---|---|
| Constant-Current | ~70% | 5-8 hours | Fast initial charge. |
| Topping Charge | ~30% | 7-10 hours | Ensures full charge and battery well-being, akin to resting after eating. |
Therefore, the total charging time is the sum of these two phases. The minimum total charge time would be 5 + 7 = 12 hours. The maximum total charge time would be 8 + 10 = 18 hours.
