A 5V 2000mA charger works with a 3.6V 1800mAh battery. The 5V voltage allows current to flow into the battery. Make sure the battery type is compatible with the charger. A weaker charger may not fully charge the battery, but it won’t damage it. Always choose a compatible charger for best results in charging safety and performance.
Lithium batteries typically require specific charging voltages to charge safely and effectively. A 3.6V lithium battery can handle a maximum charging voltage of approximately 4.2V. Therefore, a 5V charger exceeds this limit, potentially causing overcharging. Overcharging can lead to overheating, reduced battery life, or even hazardous situations such as battery swelling or explosion.
The current output of 2000mA from the charger is another consideration. The battery, rated at 1800mAh, represents its capacity, not the charging current. While the battery can accept a higher current, charging at a high rate may generate excess heat.
In summary, using a 5V 2000mA charger with a 3.6V 1800mAh lithium battery is not advisable due to voltage incompatibility. Understanding these factors is crucial in ensuring safe battery charging practices. Next, we will explore safer alternatives for charging lithium batteries.
