The charging efficiency is estimated at 85%. This calculation shows that it will take approximately 11.76 hours to fully charge the battery under these conditions.
How do you calculate battery capacity?
If the capacity is given in amp-hours and current in amps, time will be in hours (charging or discharging). For example, 100 Ah battery delivering 1A, would last 100 hours. Or if delivering 100A, it would last 1 hour. In other words, you can have "any time" as long as when you multiply it by the current, you get 100 (the battery capacity).
Can You charge a battery with more current?
You can charge a battery using more current to decrease the charging time, but not all batteries are designed that way to handle more current.
