How to calculate the charging time of rechargeable batteries? What is the best charging time for lithium batteries? Charging is an important step in the use of rechargeable batteries, proper and reasonable charging is good for extending the life of the battery, while brutal and reckless charging will have a great impact on battery life. At present, lithium batteries are basically packaged separately according to each product, not common to each other, so each product also provides its own charging equipment, the following small take you to understand the lithium battery charging time.
How to calculate the rechargeable battery charging time
Most of the battery capacity size is indicated on the battery, in milliamps, the larger the value of the larger capacity. At the same time, the charger is also generally marked with the charging current, also in milliamps.

1, charging current ≤ 5% of the battery capacity: charging time (h) = battery capacity (mAH) * 1.3 / charging current (mA)
2, charging current > 5% of the battery capacity, ≤ 10%: charging time (h) = battery capacity (mAH) * 1.5 / charging current (mA)
3, charging current > 10% of the battery capacity, ≤ 15%: charging time (h) = battery capacity (mAH) * 1.3 / charging current (mA)
4, charging current > 15% of the battery capacity, ≤ 20%: charging time (h) = battery capacity (mAH) * 1.2 / charging current (mA)
5, charging current > 20% of the battery capacity: charging time (h) = battery capacity (mAH) * 1.1/charging current (mA)
Lithium battery charging time how long is better
General 2-3 hours after the phone shows that the electricity has been full, and then half an hour with trickle so that the phone is indeed sufficient for the best effect, now the lithium battery factory have been activated aging, without the user for three twelve hours of charging, professionally trained salesman will explain to you, overcharge more than eat no benefit.
1, many people are accustomed to sleep at night when the phone is put there charging, but in the morning up to find that it is still not full, so put there again to charge it will be full. This practice is not good, the phone is charged for too long on the battery damage, and when the phone is charged full will automatically discharge, and then slowly filled, and continue the process, so there is no need to then charge.
2, all think that the phone power completely consumed before charging will be better for the phone battery, which is also completely wrong, and even cause the phone can not charge the situation, when the phone shows low battery to charge when plugged into the charger, so that the phone battery better.
3, some people think that just bought the phone to charge 12 hours, and to charge three times, this idea is wrong, the previous lithium battery does have to be charged in this way to fully activate, but now just bought the phone bar the original electricity used up, full can be.
4, lithium batteries at least once a month trickle charge, that is, slow charging until full, many battery software will remind to do so
5, now the phone charging is quite simple, use up on the charge, full to stop charging, convenient and fast. Try to use less rechargeable battery charge, although there is no exact data to say how much damage the rechargeable battery on the phone, but it is better to use less.
Lithium batteries should be fully charged for long-term storage, otherwise there is damage to the battery, now you should charge 2-3 times in a row for 10 hours - 12 hours to activate the battery. Later you can resume normal charging. Found that the battery use time significantly brief is can repeat this step to activate the battery.
