Rechargeable Battery entire Tactics

 ”A cell” includes alkaline Battery, Meng zinc batteries, such as Chongqing, a train of gold on the market batteries are alkaline batteries. Disposable batteries are cheap, easy to use, and alternative brand names. However, its disadvantages are also more lethal, first of all can not be recycled, one-time investment was low, but the cumulative use of the high cost. Another disposable Battery arbitrarily discarded after use, then, will cause environmental pollution. At present, many countries have adopted a management “a cell” of the relevant laws and regulations. I personally feel that a “one cell” is not much to purchase necessary.

“secondary battery” includes the type of respect very much on the market are more common nickel-metal hydride batteries, nickel-cadmium batteries and lithium batteries. Nickel-metal hydride batteries and nickel-cadmium batteries are the same appearance, and is divided into AA and AAA. The same as the rechargeable battery. But their works are not the same, nickel-cadmium batteries are extremely nickel oxide, the negative is extremely spongy metal cadmium, mostly electrolyte, potassium hydroxide, sodium hydroxide alkaline solution. Ni-Cd battery compact, rugged, shock, vibration, the self-discharge is small, suitable for the use of high-current discharge. It is characterized by long cycle life, in theory, there are 2000-4000 times cycle life.

nickel-metal hydride batteries are low-voltage nickel-metal hydride Toshiba PA3356U-1BRS Battery, to Ni (OH) 2 as the cathode to hydrogen storage alloy as negative electrode, potassium hydroxide alkaline aqueous solution as electrolyte. Ni-MH battery than the energy density (that is, an equal volume of batteries, Ni-MH batteries have greater capacity than the nickel-cadmium batteries), in theory, Ni-MH Battery is the energy density of nickel-cadmium batteries 1.5-2 times; there is Ni-MH battery is good environmentally friendly, Ni-MH batteries do not use metal cadmium, or use of toxic substances, does not pollute the environment; there are Ni-MH battery has largely eliminated the “memory effect.” That the memory effect and battery capacity of the increasingly high demand in the civilian grade nickel-metal hydride batteries are already replaced the nickel-cadmium batteries.

Lithium batteries can be understood as digital products, special batteries, its shape according to the design of digital products can be arbitrarily changed, lithium batteries almost no memory effect, and use a long time. However, lithium batteries are expensive, and between the different specifications of the lithium batteries can not be generic.

purchase items

the rechargeable batteries are printed on the surface of a similar mark, indicating this product is what type of battery. NI-MH says that nickel-metal hydride batteries, is actually very simple, NI is the chemical letters Nickel, NH, said hydrogen. By the same token NI-Cd is expressed as a nickel-cadmium batteries.

the battery rated capacity refers to a certain discharge conditions, the battery discharge to the release of electricity cut-off voltage. No. 7 currently on the market capacity of the battery 400mAh-900 mAh mostly between the 5 batteries from 1000 mAh-2500 mAh range. Of course, in a sense, the capacity is of course the bigger the better, because of large capacity means longer Battery life.

Marketed in some of the work packages battery capacity is also very high, but I do not recommend to buy. Because the battery in the factory hours in order to A, B, C 3, B, C-class product is mainly the product capacity, most of these products is that the battery pack work available in the market. Also noteworthy is that among the different capacities of batteries do not mix. For example, three 2300 mAh of the batteries 1300 mAh, which emit an effective current of only 1300 mAh, from the physics can be very simple to understand this point.

Also, when buying batteries may wish to consider under the Sanyo, Panasonic and other major brands and other products made in China is also a good source of Qi. Other unknown product is best not to buy, while the purchase rechargeable batteries, they can weigh about weight. Generally heavier weight, the better its quality. Here I teach you a trick Identification of true and false Sanyo batteries, Sanyo battery cathode is not completely round, but a little bit of a square, while Haier, Sanyo batteries agent the highest only at 1850mAh.

Ordinary rechargeable batteries(IBM ThinkPad T21 Battery) are marked on the standard charge time and quick charge time, charging the speed with charger related.

Slow charge mode commonly used constant current charging, the battery is full and automatically to trickle charge state. Has the advantage of slow charge circuit design is simple and easy to implement, prices are also lower; As a result of low current constant current charging, effectively reducing the battery charging process in the heat, to extend the Dell Vostro 1310 Battery life is very good. Drawback is the charging time is too long, especially in the case of large quantity of batteries a bit powerless.

Fast charge is generally using a large pulse current charging, but because of high current battery charging process will generate polarization response, leading to the rapid increase in temperature, full power on after resume a likely explosion and combustion, So, fast-charge and features a dedicated chip to control the charging process, automatically stop charging once filled so that the whole process of charging has become safe and efficient.

In the end is a standard charger or optional fast charger that can be purchased according to the needs of users. Here to remind consumers to purchase brand-name products charger must be, and if I get quick charger, be sure to understand whether the automatic power-off function.

battery maintenance

The use of rechargeable batteries users. Bought back the battery power is low in general, the first charge must be adequate. Ni-MH battery charging time are generally more than 16 hours. To achieve best results, generally more than 3 times repeated charge-discharge can. In addition, the Battery in use after three rounds, the best place to find the opportunity to make a further charge fully recharge, so as not there is residual power in the battery when the repeated charge, or will shorten battery life.

In addition, in order to avoid the loss of electricity, use nickel-metal hydride battery user, remove the battery charge after the power end, do not let the battery positive and negative poles at the same time contact with conductors. And not to frequent deep discharge of the HP 530 Battery, as this will affect the battery’s chemical properties. And do not mix old and new batteries.
