Can the lithium battery deflate after bulking?

Battery bulge affect after use, put not into the mobile phone or digital camera, the other battery plate between the presences of gas can also affect the charge and discharge capacity of the battery. Deflated can restore the original size, after normal use.

The lithium battery choose near the top of the sealed lid under the (note that don't punch a hole in the bottom of the battery, there is no space), to avoid the electrode punch.

Below is the, on both sides of the two electrodes in drilling in the middle. Now is the aluminum shell, with very fine instrument screwdriver can use hand drill, drill must be in-depth, after to avoid encounter danger, such as electric plate.

With luck, will hear have ran out of gas after pierced through sound, bad luck is what action also have no, the battery can't use again, need to change batteries.

Summon the parts can be appropriately squash with the hand after 47 help plate between the gas discharge.

In the end, it is not on the adhesive seal to avoid into the air. It can use some 705 silicone sealant and so on.

Can see the cover the front end of the reserved space

Pay attention to the position of Mr. Wrong battery may appear local short-circuit spark fever phenomenon. This position is not suitable for drilling.

Destroy the battery itself (here said the battery is batteries itself), batteries is inside a vacuum system, once the external damage, battery not far from the bad is, the most direct phenomenon is up.

Battery overcharge, this is the most know, overcharge is caused by the charger is bad, more than 4.25 V batteries voltage will be basic, performance good batteries may discharge voltage drop in for a while and then no problem, serious may be unable to recover, even the pressing force is useless, generally it is difficult to flatten and external forces, which is just said the cause of the vacuum, or completely sealed more accurate)

Is the battery discharge, discharge standard is the batteries voltage is lower than 2.7 V, general is less than 2 V voltage after a lot of batteries have summoned the phenomenon, if less than 1 V the toilet!

Other factors, in addition to the above 3 points, there are some unpredictable factors, such as charging high transient voltages (could be more than 5 v), the instantaneous electric current too high (e.g. short-circuit current infinity).

Float charging voltage is set too high, the charging current is big, lead to increased oxygen precipitation on the positive plate, and too late in the cathode compound, at the same time, the temperature rise of cells in the body quickly, the exhaust, pressure reaches a certain, the bulge deformation of valve control type sealed lead acid battery.

Valve control type sealed lead acid battery in charging operation especially in series battery pack, if for charging the battery pack, if you have poor quality batteries often arise within gas composite adverse phenomenon, which appear beat phenomenon. According to the above situation, the users in the use of valve control type sealed lead acid battery to make the small float charging voltage, charging current down; Don't use the poor quality of the battery.

Very sure to tell you, can't angry! Seal is vacuum sealed, is to prevent water entering. You don't have a vacuum condition in the home, even if there is no laser welding, and seal, the square aluminum shell is vacuum hit a ball, soft bag of polymer is PP vacuum heat fusion layer.
