<h1>What's mean Protection Circuits (4)?</h1>

<div align=justify>What's mean Protection Circuits (4)? Li-ion <A href="http://www.good-battery.com">batteries </A>with cobalt electrodes, for example, require full safety protection. A major concern arises if static electricity or a faulty charger has destroyed the battery’s protection circuit. Such damage often causes the solid-state switches to fuse in a permanent ON position without the user’s knowledge. A battery with a faulty protection circuit may function normally but does not provide the required safety. If charged beyond safe voltage limits with a poorly designed accessory charger, the <A href="http://www.good-battery.com">battery </A>may heat up, then bulge and in some cases vent with flame. Shorting such a <A href="http://www.good-battery.com">battery </A>can also be hazardous. Manufacturers of Li-ion <A href="http://www.good-battery.com">batteries </A>refrain from mentioning explosion. ‘Venting with flame’ is the accepted terminology. Although slower in reaction than an explosion, venting with flame can be very violent and inflicts injury to those in close proximity. It can also damage the equipment to which the battery is connected. Most manufacturers do not sell the Li-ion cells by themselves but make them available in a <A href="http://www.good-battery.com">battery </A>pack, complete with protection circuit. This precaution is understandable when considering the danger of explosion and fire if the <A href="http://www.good-battery.com">battery </A>is charged and discharged beyond its safe limits. Most battery assembling houses must certify the pack assembly and protection circuit intended to be used with the manufacturer before these items are approved for sale. more info:<A href="http://www.good-battery.com">www.good-battery.com</A> </div>
