How is it to determine that the battery is absorbed? What is the re-renewal of the old battery repair? How to advertise the battery damage, discuss, price, etc. in the scene, so as not to occur unnecessary misunderstandings and trouble? This is to determine the damage of the battery and the degree. Open the battery pack cover, check the battery to be repaired without hot off the connection line.

Online inspection Important includes the following inspection content: (1) Wan-by-Structure is in DC 20V file, measuring single battery airborne terminal voltage, generally should be over 12V. If the voltage is above 10.5V, this battery has a possibility of short circuit; if the terminal voltage exceeds 13.

4V, it means that the battery is less serious, and even vulcanization occurs; although some battery terminals do not exceed 13.4 V, there is also There may be severe downtime. This is because: 12V battery consists of sixge, 5 of which have serious water, but there are other problems in one, the total open circuit does not exceed 13.

2V. (2) Discharge the single battery with a 12V100W car bulb or 24V300W halide bulb while measuring battery-side voltage. If the battery voltage drops slower, it is not deep, it means that the temperature can be repaired; if there is a voltage drop of 2V, it will illustrate that there is a backward single-density exist; (3) is connected in series, and connect the tonar, the battery pack ( 36V battery pack as an example) discharge.

Normally, a group of batteries to be repaired is generally damaged by a battery, known as backward batteries. When the battery pack end voltage drops below 34V, if the battery pack is constrained as the same diarypse, it can be judged behind, and the battery must have a backward single. Measure a single battery voltage to find a battery backward battery.

You can also measure a single battery with a battery fast capacity tester to find a backward battery, and repair the backward battery can be repaired. ⑷ Take the multimeter to measure the battery terminal voltage of 12V, even higher, but with the light bulb is discharged, the bulb is not bright. Clamp the positive electrode with the fish clip, the other end is blowing on the negative pole.

If the flow of the wire is not seen, it can judge the battery opening; This situation is very likely that the battery has a single single; there is a situation, some of the poor quality batteries, due to the irregular materials, will result in the pole group extraction terminal under the underside of the extract The shape of the spindle, the battery is sometimes in a semi-open state, sometimes in an open state, when charging, the angle heat or open rechargeable charge is not advanced; the battery end voltage is about 0V, which is generally long battery placement time. Due to the original battery self-discharge and polar vulcanization, it is completely loss of battery capacity, causing severe irreversible vulcanization. This failure mode is often very similar to the open circuit cell, especially completely open battery, and the end voltage is about 0V, distinguishes to this.

The above test methods should be used to be used. It cannot be used to test the crash conclusions only with a means of testing; the failure of some batteries should be made, and even the anti-push method to verify the judgment. In short, the inspection and judgment of the battery failure is a affirmation - negation - no sure - negation - the final affirmation process.

The general operation process of the battery repair is: Check the battery if there is maintenance, maintenance value → Solve the disease → test solution → Determine continuous maintenance or elimination → continuous repair → test effect. .
