Each battery is designed with a nominal voltage, typically 3.7 volts per cell. A 12V charger usually outputs a voltage compatible with some lithium-ion battery configurations, which can consist of multiple cells in series.
When using a charger, the voltage must match the battery specifications. A 20V battery generally consists of five lithium-ion cells in series. Therefore, it requires a charger that delivers approximately 20 volts. Using a 12V charger on a 20V battery typically results in insufficient charging. The battery will not charge fully or might not charge at all.
Additionally, lithium-ion batteries include a built-in management system. This system helps regulate voltage and current during charging. It ensures safety and prevents overcharging. If a charger outputs too high a voltage, it can damage the battery. Conversely, too low a voltage may lead to inadequate charging.
In summary, lithium-ion technology dictates strict voltage and current compatibility between chargers and batteries. Adhering to these specifications is crucial for safe and effective charging.
