How to determine whether the battery repair, how to recover the old battery backup?

To open a shop to repair the battery in terms of entrepreneurs and how to recycle old batteries back from the repair? Customers in the area of how to recognize the damage the IBM ThinkPad R50 battery and replace consultation, price and other conditions in order to avoid any difficulties later misunderstanding and unnecessary? This need to determine the nature and extent of damage to the battery.

Open the lid of the son of the battery, the cable will not burn the battery status under the inspection and necessary repairs. On-line inspection, the review included the following:

⑴Digital Multimeter aside in the range 20V DC files, without measuring the battery terminal charging voltage alone, the general should be more than 12V.

If voltage is 10.5 V and below, indicating the existence of this part of the battery short-circuit in May;

If the voltage exceeds 13.4V, water loss battery more serious, and treat even occurred;

While some voltage across the battery does not exceed 13.4V, but there are also potentially serious dehydration. This is because: 12V battery 6 cells, five cells with severe dehydration, but there are other issues, a grid with a total voltage in open circuit is higher than 13.2V would not have had.

⑵ 12V100W car with halogen bulb or bulbs right 24V300W only discharge the Dell Inspiron 1100 battery while measuring the voltage across the battery.

If the battery voltage falls more slowly, and not deep, which indicates a high chance of repair;

If more than one sudden voltage drop of 2V, indicating that it has fallen behind on a single cell exists;

⑶ will discharge lamps in series and connected to the multimeter on the battery (in 36V battery as an example) discharge.

Under normal circumstances, a battery to be revised to one of serious damage to the battery, known behind the battery. When the voltage across the battery drops below 34V, if the battery voltage is the same water more than once fallen, can determine if there is a battery back, and the room behind the battery there must be a single cell. Measure the battery voltage only to find the battery voltage is lagging. Can also use the battery of rapid tests measure the 338794-001 battery capacity only to find a battery to the back just behind the battery can be repaired first.

⑷ with the multimeter measures the voltage across the battery up to 12V or higher, but the discharge lamps, bulbs, which do not shine.

Clip on one end of the fish caught in the positive and the other end into the ear scratching pole negative affect, as not seen the slightest spark can be considered part of the battery open circuit;

Measures of capacity such that the detector with a battery faster, you will find pointers to stay on the left the red zone did not move, this is probably one VGP-BPS2 battery cell open circuit;

There is another situation, a number of batteries of low quality due to non-standard equipment will be in a very ear leads the next group of terminals to the plate corrosion due to spit acid formed in the shape of the battery and sometimes in a semi-pass half-open state, and sometimes in the open state, the load is located at the same angle of the ear or fever can not be recharged by electricity;

⑸ around the voltage at the battery terminals is 0V, is generally placed on the battery time is very long, due to battery self discharge and baking and other reasons, is a complete loss capacity of the battery resulting in serious irreversible hardening.

These failure modes are often associated with open circuit, the battery is fully open, in particular, is very similar to the voltage of the battery terminal to 0V or so, which must be distinguished.

Detection of the integrated use of the means of the above can be done by a simple way to detect failures to conclusions, there is some other failure of the battery may require few steps to take, but also requires the use Inverse methods for verifying and concluded. In short, the battery has failed the inspection and found negative results positive - - then sure - and denied - the last positive process.
