How Many Volts Should the Battery Be? / How to Prevent Overdischarge

In this article, we will discuss the ideal voltage for batteries and how to prevent them from over-discharging and rapidly depleting.

As known, rechargeable products such as batteries and lithium-ion cells can become unusable if they are over-discharged. So, what can be done to prevent this situation? Let's learn together in this article.

The voltage written on batteries indicates their operating voltage. The battery voltage should always be kept close to this value. Otherwise, a significant decrease in voltage can lead to the end of the product's life.

 

If we examine this table, let's consider a 12V battery. As seen, for a 12-volt battery, 11 volts is indicated as the complete depletion point. So, if a 12V battery drops below this value, it will most likely complete its life cycle. 

Looking at the charging voltage, let's review the fullest level. A 12V battery can reach its full capacity only when supplied with a 14.4-volt source.

 

How to Prevent Overcharging and Over-Discharging

Based on the above information, both over-discharging and overcharging of batteries are dangerous. To prevent this, a system that can monitor the battery voltage may be the best solution.

Among our products, one of the most useful ones is the overcharge and discharge modules which can prevent your battery or rechargeable cell from being overcharged or rapidly depleted. Keeping the voltage of your battery under control is an important golden rule for being able to use your battery healthy for a long time. 

By setting lower and upper voltage limits with these modules, the battery will remain within these voltage ranges. Thus, it will neither deplete excessively nor overcharge.

 

The best way to see the voltage of batteries instantly is through battery capacity indicators. These indicators are connected to the poles of the battery and allow you to see the battery voltage instantly. Thus, you will never have difficulty in monitoring the battery's state of charge.
