AI Customer ServiceCharging new Li-ion cells properly is crucial for optimizing their performance and longevity. Here are some steps to follow: Initial Charge: New Li-ion batteries typically come partially charged (around 40-60%). It’s recommended to fully charge them to 100% before the first use to ensure cell balancing and full capacity utilization.
The basic algorithm for Li-Poly batteries is to charge at constant current (0.5 C to 1C) until the battery reaches 4.2 Vpc (volts per cell), and hold the voltage at 4.2 volts until the charge current has dropped to 10% of the initial charge rate. In addition, a charge timer should be included for safety.
The internal resistance of the battery doesn't affect the charging routine, although the charging efficiency might change. This target charge current is relative to the battery capacity ("C"). For standard Li-ion or Li-polymer batteries, chargers often target 0.5C charge current.
Replacing a LiPo battery with bigger capacity is okay, since the device's charger likely would not know this, and will charge the battery with old current, which would be below the "safe charging limit", typically 0.5C as bitsmack already explained. So it will do no harm, it will just take a bit longer to complete full charge.
This target charge current is relative to the battery capacity ("C"). For standard Li-ion or Li-polymer batteries, chargers often target 0.5C charge current. In other words, if the battery is rated at 500 mA-h, the target current is 250 mA. It is not unusual to charge at 1C (500mA), but this compromises the battery's capacity over time.
Standard Charging: Using a standard charger that supplies a typical current (usually around 0.5C to 1C, where C is the battery’s capacity), it takes approximately 2 to 3 hours to charge a Li-ion cell from 0% to 100%. Fast Charging: Some modern chargers can supply higher currents (above 1C), reducing charging time to as little as 1 hour.
