Common Causes of Battery Failure - Part 2

All batteries will ultimately fail, stop working, and no longer operate, and / or otherwise end their useful life. It is the reality of a consumable product. But sometimes batteries can warp, bubble, and even explode! Batteries can also fail incompatible designs or incorrectly selected hardware and batteries can fail due to customer misuse or abuse.

According to the U.S. Consumer Product Safety Commission, each year, deaths, injuries and property damage from consumer productIncidents cost the U.S. taxpayers more than 700 billion U.S. dollars annually. This cost includes more than 15,000 different products, the risk of fire, electrical, chemical, or mechanical hazard or products that may hurt the children (cribs, toys, etc. present). Batteries are by their nature 1 of the 15,000 products the CPSC monitors because of the increased integration of battery types, increased energy pack in smaller packages. Batteries with lithium ion and lithium metal polymer chemistryare thinner, smaller and lighter designs still contains more energy than traditional batteries. These battery types are an excellent choice for small electronic devices that require higher capacity and specialized hardware to do the battery, everything else as well performing as expected within the device requiring protection.

It is true that some batteries can warp bubble, and even explode. It is also true that batteries can not. According to the U.S. ConsumerProduct Safety Commission has 339 battery overheating incidents were recorded in context. 339 cases of overheating, sounds like a lot, but if the battery is far more than 100,000,000 compared to similar devices that are purchased by consumers since 2003, a very small percentage (.000003) of all battery types similar devices on the market.

The reason why in batteries overheating to the point of warping, bubbling and explosion is one of the following reasons:

1.Incorrectly chosen hardware - from the plug, the fuse of the charge and discharge FETs, the cell pack, the feeling of resistance, the primary and secondary protection ICs, the fuel-gauge IC, the thermistor or the board.

2. Uncontrolled Manufacturing Processes - also badly run production facilities, in the cell short circuits, leaks, unreliable connections lead, sealing quality, mechanical weakness, and pollution.

Batteries can also fail customer abuse orAbuse. Battery abuse may, in a variety of ways, but all forms of abuse battery has not been done under the following categories, including altitude simulation, temperature fluctuations, shock, external short circuit, impact, overcharge, forced discharge.

Finally, batteries can fail due to abuse of consumers. Abuse is different, because it is intended to consumer misuse abuse battery interruption of battery and battery misuse is unintentional abuse of consumer batteries. For example, a commonAbuse of a battery is trying to use a battery rated and intended for a PDA, camera, or iPod model was developed, but uses the battery for a completely different device. It may sound funny, but it happened. Why, because consumers believe that only because the physical presence of the voltage and the same capacity that the battery will operate in multiple devices. This is a fallacy that often happens. To avoid this kind of abuse, you only use a battery specificallydesigned for the device model you own and do not exchange battery.
