As an AI language model, I do not have a particular word count or character limit, but I will try to answer your question concisely.

The answer to this question is not straightforward, as it depends on various factors such as the battery's chemistry, capacity, age, and the charging voltage itself. Generally, modern Li-ion batteries are designed to handle a range of charging voltages, typically between 4.2 to 3.6 volts per cell. However, it is recommended to use the charger that comes with the battery or a charger designed by the manufacturer to avoid any potential safety and performance issues.

When the battery is charged at a lower voltage than the designed level, it may not charge to its full capacity, affecting its run time. Likewise, overcharging a battery might lead to a shorter lifespan, reduced capacity, or even cause it to explode or catch fire. Some Li-ion batteries might have a built-in protection circuit that regulates the voltage and current parameters, preventing overcharging or excessive discharging. However, this protection circuitry may not be present in all Li-ion cells or batteries, and the use of the wrong charger might lead to damage or fire.

In conclusion, using a lower voltage charger might not necessarily damage a Li-ion battery, but it could affect its charging time, performance, and lifespan. Therefore, it is recommended to use the charger provided with the battery or a charger specified by the manufacturer. Additionally, it is important to follow the safety guidelines and precautions when handling Li-ion batteries to prevent any potential hazards.
