subject: how to tap the potential of the battery [print this page] Recently, many people are very concerned about their friends, love machine rechargeable battery issue. A wide variety of brands available in the market model is, indeed, confusing, we summarized the doubts and discussions with everyone now use digital cameras to the performance of batteries and how to tap the potential of the battery, and finally talk about how the service and maintenance, so you go out when shooting a better idea. In addition: Many cameras such as Sony series, and some other mini machines (comes with simple chargers) use the more expensive the battery out of the general AA Ni-MH rechargeable battery with a large, quality is good, endurance capacity, compared to people at ease. Most digital cameras use AA rechargeable battery market, many brands use to find the quality quite different apple Laptop Battery toshiba laptop battery .
We have the most popular cheap and good AA rechargeable batteries and discussion: digital camera battery into commonly used lithium-ion batteries, nickel-hydrogen batteries, nickel cadmium batteries, alkaline batteries, etc., the most popular is also the most mature technology Ni-MH battery by everyone's favorite.
Nickel Metal Hydride (NIMH) battery's advantages: its discharge curve is very smooth to the consumption of electricity is about to complete, the voltage will suddenly drop. Ni-MH is a nickel hydroxide for the positive and negative energy of hydrogen storage alloys, nickel-hydrogen batteries so the positive and the same nickel-cadmium batteries, but energy storage alloy negative electrode materials used to make nickel-metal hydride batteries with more energy. At the same time in the electrochemical characteristics of nickel-hydrogen batteries and nickel-cadmium batteries are also similar, so when using NiMH batteries can completely replace the nickel-cadmium batteries, the device without the need for any reform. The battery is not mercury, is very conducive to environmental protection, a slight memory effect.
Ni-MH batteries using special attention to the following Thinkpad r50 battery IBM thinkpad r32 battery Thinkpad x41 series battery SONY VGP-BPS2 Battery:
1, note the temperature of charge, this is very critical. Normally, we should be 0 C to 40 C of ambient temperature batteries. Because of lower than 0 C under the internal rechargeable battery will not charge properly, resulting in irreversible decline of performance. Higher than 40 C in recharge, there will be caused to leak possible. (This is why a few friends after the battery charging method in excess iron, the outflow of liquid yellow reasons.)
2, beginning as far as possible not to use nickel-metal hydride battery trickle charge. However, after the fast charging of the battery can 0.033CmA complement to 0.05CmA trickle charge (fully activated electronic). Charging the same time to avoid excessive use of trickle charge mode, this will damage the battery's characteristics IBM thinkpad r52 battery Thinkpad x22 battery IBM thinkpad t42 battery IBM thinkpad r51 battery, use timers to control the charging time. (Note: "CmA" in the charge and discharge process, CmA a specified size and that the battery current value of the rated capacity, "C" refers to the rated capacity of the battery.)
