How long is appropriate for the second charge of a new battery?
2 Answers
Before the second charge of a new battery, it should be charged when the power is almost depleted, and the charging time should be 8-11 hours. Remember, the second charge should be sufficient, as this time is crucial. The second charge should last 8-11 hours, with the purpose of this one-time extended charging being to allow the battery's chemical reaction to complete a full cycle, but it should not exceed 12 hours. Here are the methods for charging a new electric vehicle battery: 1. Before the first charge of a new battery, the power should be used until only the last bar remains before charging; do not charge immediately after replacement. Wait until the battery's power is down to the last bar, which is when 20-30% of the power remains, as this is the optimal time for charging. 2. The first charge of a new battery generally takes 5-7 hours, and it is best to charge during the day. 3. If the electric vehicle is not used for a long time, charge it once a month to prevent the battery from discharging. Long periods of inactivity can lead to battery discharge, causing battery depletion, so it should be charged once a month to maintain battery stability.
As a veteran driver with twenty years of experience, I've seen plenty of issues with new batteries. Don't be careless when charging a new battery for the second time—make sure it's fully charged. Generally, I recommend charging it for 8 to 10 hours to be safe. The exact time depends on your charger's power and the battery's capacity. For example, a small 50Ah battery with a standard 2A charger might need about 10 hours, while a larger 70Ah battery could take around 12 hours. Just don't overcharge it, as overheating can damage the electrodes. Proper initial charging is crucial for a new battery—it extends its lifespan and prevents premature failure. I also make it a habit to check the battery terminals every few months to keep them clean and prevent leakage. In short, take your time—don't rush and end up wasting money. I learned that the hard way when I hurried a charge and had to replace the battery sooner than expected.
