How to repair the 6V battery after 3 years

I don't know if it can be used. You activate and try. Here's how:

Under normal use conditions, the cycle life of lead-acid batteries can reach more than 300 times, and the floating charge service life is 3-5 years. However, if it is not used properly, such as over-discharge, over-charge, short circuit, or long-term non-use, etc., it will lead to premature aging of the battery, and the battery needs to be activated.

If the battery cannot be charged, the high-voltage method can be used, that is, the output voltage of the regulated power supply for charging is slowly increased, and in this process, the charging current is monitored with an ammeter. If you notice a slow increase in the charging current, the activation has been preliminarily successful. Then let the battery be charged at the rate capacity current for more than ten minutes, and then the voltage can be lowered to the normal value and continue to charge until it is fully charged.

If the high-voltage method is ineffective, the reverse charging method can be used, that is, the positive electrode of the battery is connected to the negative pole of the stabilized battery, and the negative electrode is connected to the positive electrode of the battery. Note that the recharge process is very short-lived, just a few touches of the electrodes. You should be able to see a very large battery during this process.

After reverse charging, the battery can be activated by the high-voltage method. If the internal resistance of the battery is too large, or it is so dry that even the reverse charge is ineffective, the liquid exchange method should be used, that is, the electrolyte inside the battery should be replaced and replenished. Usually, the battery can be activated by high voltage after a liquid change.

Generally, premature aging lead-acid batteries, after using the above methods, can be brought back to life, and the capacity is similar to that when newly bought. If the liquid change is ineffective, the battery will basically be scrapped. The most likely cause is that the oxide layer has accumulated on the plates is too thick.

At this time, there is a final method, that is, the upper cover of the battery is sawed open, the inner body of the battery is taken out, the plate is scraped clean manually, the liquid is changed thoroughly, and then the single grid is connected, and the lead wire is connected at the same time, and finally sealed with epoxy resin. However, this method is of little significance, because the internal damage of the battery may be caused during the repair process, so it is not recommended.

Well-maintained lead-acid batteries can usually be used for 5 to 6 years, and the battery can be charged and discharged with a battery activator to check the capacity and repair it.

The length of time that is placed with bai

Whether it is related to regular maintenance.

The DAO life of the ZHI maintenance-free battery is generally 300 times of full charge and discharge. The battery is a consumable, and it is very high, so it is very necessary to use and maintain the battery correctly and extend the service life of the battery to achieve the best use of the battery. This 300 times is calculated based on the battery capacity dropping to 75% of the nominal capacity, which is important because the user will not charge the battery when it is only 75% of the capacity, but will charge it when there is really no way to use it, at which time the battery capacity has dropped to 40% of the nominal capacity, that is, there is an overdischarge.

Therefore, the battery is not used, and it also needs to be maintained and maintained regularly

Timely charging (the battery must be fully charged and stored): the vulcanization process begins after the battery is discharged, and obvious vulcanization will appear after 12 hours, and timely charging can remove the not serious vulcanization. If it is not charged in time, the vulcanization crystals will accumulate and block the velvety lead micropores in the battery, which will increase the internal resistance of the battery and reduce the service life of the battery.

Timely hydration: The battery is designed with a lean liquid type, and there will be gas separation during the charging process, resulting in the distilled water of the electrolyte in the battery gradually decreasing until it dries up. This will cause the battery capacity to decrease, so it is necessary to replenish the distilled water in time.

If it is a maintenance-free battery, you can look at the battery cover and safety valve, if the white separator of the battery is dry, you need to replenish the water immediately. If it is a general lead battery, you can check the water level, and if the electrolyte level is below the standard line, you should replenish the distilled water.

The battery life on the car is generally about three years, if you are careful to use it, you can go to five years, the battery voltage should be within the no-load voltage is about 13 volts, the load capacitance voltage is not less than 11 volts is normal, below this voltage may be difficult to start, after starting because the generator began to generate electricity 12 volts car voltage should be between. The 24-volt car system is between 27 volts and 29 volts, and the generator voltage is measured after starting, because the battery and the generator are working in parallel, the battery voltage cannot be measured at this time. Your battery 8 9 volts, I don't know if you use a battery measuring instrument or a multimeter, if you use a multimeter, it is obviously a bit low, it seems to be a loss of power, otherwise the measurement after starting should not be low, if so, you should remove the battery for supplementary charging, otherwise it will have a certain impact on the life of the battery, you go to the 4S shop and say that the cold car is difficult to start, and it will not catch fire after two days of placement, etc., ask for replacement, and the attitude is tougher, it should be replaced for you.

Nowadays, more and more people use electric vehicles, but they don't understand the relevant knowledge of electric vehicles, and find that electric vehicles are not used for a long time, so today I will tell you some bad habits to avoid when using electric vehicles and how to charge the best way to protect the battery!

1. Don't charge frequently, because people often use electric vehicles nowadays and develop the habit of charging once a day, but the battery life is related to the number of charging cycles, and frequent charging will also reduce battery life. Therefore, it should be charged when there is still about 30% of the battery left, which can effectively extend the life of the battery.

Second, if it is an electric car that you just bought, you must press it to be fully charged before riding.

The battery in the new electric car has been lost when it circulates in your hands, and if it is not fully charged and ridden directly, it will accelerate the battery loss, which is not conducive to battery maintenance.

3. If you don't ride for a long time, you should charge it on the first day of January.

Fourth, do not charge under the high temperature storm knowledge of Yinchang.

During the charging process of the battery, heat will be released, and high temperature exposure will easily cause the battery to bulge, affecting the life of the battery.

Generally, it is changed every 2-3 years.

Maintenance: 1Don't just change the charger and don't remove the speed limit of the controller.

2.Pay attention to the charging environment. The optimal ambient temperature for charging is 25 . Nowadays, most chargers do not have an automatic control system that adapts to the ambient temperature, so most chargers are designed according to the ambient temperature of 25, so it is better to charge under the condition of 25.

3.Recharge every day.

4.Charge in time. In addition to charging every day, it is also important to charge the battery as soon as possible after use to keep the battery as full as possible.

5.Periodic deep discharge. It is also beneficial for the battery to undergo a deep discharge on a regular basis"Activation"battery, which can slightly increase the capacity of the battery. The general approach is to make a full discharge of the battery at regular intervals.

Experienced users know that the cost of the battery is the biggest consumption of the electric bike, so the user is very concerned about the issue of extending the service life of the battery, and whether the user uses it correctly is crucial to the life of the battery.
