Common Mistakes in Using Batteries
-There are some mistakes that can lead to damage to electric batteries, especially solar batteries, which may discharge unexpectedly quickly within just two or three hours.
-One cannot judge that the batteries have been damaged due to rapid discharge; rather, one must know the value of the charging current from the general grid and the amount of charging current from the solar panels, as the batteries may not be fully charged.
-What are the common mistakes in using batteries?
1.First mistake:– Not charging the battery or batteries properly and deeply discharging them to the extent of 80% to 100% (i.e., completely or nearly completely discharging them).
2.Second mistake:-The reason for not fully charging solar batteries from the solar panels, even though the amount of drawn current is low (i.e., within the good range), may be due to not regularly cleaning the solar panels from dust and dirt, or other reasons such as inappropriate and low charging current settings.
3.Third mistake:– Drawing a high current from the batteries by loading large loads, which leads to the batteries discharging very quickly. For instance, operating a 1200-watt air conditioner on a 200Ah-12V battery might seem feasible, but the air conditioner will discharge the battery completely in just an hour and a half. This is impractical and illogical, causing the batteries to wear out quickly and suffer significant damage.
4. Fourth mistake:- Choosing an unsuitable charger for charging the batteries. For example, selecting a charger that provides 50 amperes to charge a 100Ah battery, aiming to speed up the charging process, is a critical mistake that causes the batteries to deteriorate quickly. Thus, there must be coordination between the charging current and battery capacity.
5. Fifth mistake:- Directly connecting to the battery without any protection against deep discharge leads to a sharp voltage drop (i.e., completely discharging the battery), thereby reducing its lifespan.
6. Sixth mistake: Incorrect placement of the battery in an inappropriate location.
-How to Extend the Life of an Electric Battery
– Avoid directly connecting DC loads to the battery.
– Avoid overloading the battery.
– Choose a high-quality charger with a charging current that matches the battery capacity.
– Place the battery in a location away from sunlight and other heat sources, ensuring good ventilation.
– Fully charge the battery and avoid fully discharging it. It is preferable to discharge gel batteries and AGM batteries by 50%.
– Disconnect unnecessary loads from the battery.
– Ensure the battery capacity matches the size of the electrical loads.
– Ensure the solar panels are equivalent to the battery capacity, meaning a 200Ah battery needs a 400-watt panel to charge properly.
In Addition
1. Connecting the batteries by unqualified individuals.
2. Maintaining solar batteries at vehicle battery shops, known as “banshar.”
3. Connecting tubular batteries with gel or AGM batteries.
4. Connecting batteries of different capacities together.
5. Connecting expired batteries with new batteries
6. Irreversible sulfation. Fault phenomenon: Plate sulfation is a common fault in batteries, and many battery failures also occur due to this fault. The main manifestations of plate sulfation are: rapid voltage rise during charging, premature gas release, and rapid temperature rise; During discharge, the voltage drops rapidly and the capacity is small.
7. Transform. Fault phenomenon: Battery deformation is not sudden, it often has a process. The battery enters the high-voltage charging zone when it is charged to about 80% of its capacity. At this point, oxygen is first released at the positive electrode, which passes through the holes in the separator and reaches the negative electrode.
8. Short circuit. Fault phenomenon: The battery voltage drops by an integer multiple of 2.
9. Battery leakage. Common night leakage phenomena: firstly, poor sealing between the upper cover and the bottom groove or cracking of the sealing adhesive due to collision; secondly, acid leakage from the safety valve; Acid leakage at the three terminals; Acid leakage occurred in four other areas.
.And many other mistakes that can be easily avoided if we seek technical advice from specialists.
-In conclusion, we have clarified the most common mistakes in using batteries that most people might encounter.**
