What Causes Batteries to Fail?

Why do not batteries? Can there be such a thing as a bad battery? How do I know if my battery is bad? The most effective means of understanding the status of a battery will test the battery with a battery analyzer. However, since this may not immediately for you, we want to investigate some of the ways that a battery could lead to "insufficient" and I understand some things you can do to isolate it, if a battery is bad, in fact, .

Especially with batterieschemistry or other cell structures are not in different ways. For example:

• Batteries can be faulty cell design

• The batteries can be produced by the uncontrolled

• Batteries may be operated in uncontrolled conditions

• Batteries can be abused

• Batteries can degrade and lose power

Battery Cell Design Faults - are weak mechanical design, inadequate pressure seals and vents,the specification of inferior materials and incorrectly specified tolerances can be responsible for many potential failures.

Uncontrolled manufacturing technologies include - badly run production facilities which in the cell short circuits, leaks, unreliable connections lead, sealing quality, mechanical weakness, and pollution. Become an example of a manufacturing method of control is variable thickness of the active chemicals on the electrodes would affect cell can,Impedance and self discharge.

Uncontrolled conditions

Perfectly good batteries, if you are working under conditions where they would not be: the use of the battery in a device that (it's not designed for, to recharge the battery with an incorrect charger / adapter, extreme environmental conditions, most handheld consumer batteries operate best at an ambient temperature of 32 ° C-95 ° C.), and physical damage.

Abuse

Abusethe deliberate ill-treatment by the end user as well as accidental abuse which may be unavoidable. This may also fall, crushing, penetrating, impacts, immersion in fluids, freezing or exposed to fire.

Battery degradation and power dissipation

A battery degraded over time and eventually stops working, this is no surprise, but why this happens is really a fascinating yet technical process. These reasons are complex issues which are far more than user control, and are completely separatedwithin your battery and your device! These reasons for battery degradation and power dissipation over time is due to declining capacity, improve the internal resistance, elevated self-discharge, and premature voltage cut-off for the discharge.
