How to Safe Use Digital Carema Battery

1, do not mistake the positive and negative of battery. This point is especially important to AA rechargeable batteries used in digital cameras. If battery positive (+) pole and negative (-) pole are used oppositely , it is likely to result in short-circuit bringing about battery overheating  and cause instability and even damage to the  digital camera.

2, avoid buying low-quality batteries or counterfeit ones.There are hidden safety problems in the internal circuitry and material of many poor-quality batteries . A number of mobile phone battery explosion are caused by counterfeit products.

3. charge fully the battery until it is exhausted as much as possible,which will extend battery life. In addition, lithium-ion batteries are also advised to avoid high temperature and low temperature environments, so as not to affect the use effect.

4, if long-term non-use, it is best to charge the battery to the half rated capacity . It could be placed at room temperature.Try not to let the battery contact metal objects, so as to avoid short circui.It does not only undermine the battery,but also easily cause fire.

5, As for AA rechargeable batteries,it will be better to comprise battery group with the same type batteries. Do not mix the no electricity batteries with powerful ones ,for there is a big difference in resistence  between the batteries.Once forced to use,it is likely to result in a lot of power consumption in the battery itself.It might also cause battery leakage.

Ford Picks Battery Maker Azure Dynamics

Dropping former partner Smith Electric Vehicles, Ford Motor Co. (F) will now estabish partnership with Azure Dynamics Corp. (AZD) to produce a battery-electric version of its Transit Connect commercial vehicle.

" Both Ford and Smith agreed to end our joint project," Ford spokeswoman Jennifer Moore told Dow Jones Newswires Friday. "While both companies are committed to the success of their electric-vehicle product lines, it became clear our companies were pursuing different markets."

Ford's Transit Connect battery electric vehicle will be the first of four electrified vehicles the auto maker plans to introduce over the next three years in Canada and the U.S. .

"The Transit Connect is slated to debut in 2010 with the project remaining on schedule." Moore said, Ford had picked Smith in February.The firm is a subsidiary the U.K.-based Tanfield Group PLC (TAN.LN).

Next-generation hybrid vehicle and a plug-in hybrid  in 2012 will follow  the introduction of a battery-electric Ford Focus in 2011 .

The Oak Park,Mich-based Azure Dynamics develops electric drive and hybrid electric technology for shuttle buses and commercial trucks. The new deal with Azure Dynamics will also allow Ford to tap into Azure's battery-making experience with Johnson Control Inc.

Ford shares fell 1.4% or 10 cents to $7.20 in earlier trading Friday. The company will report the third-quarter earnings Monday.

How to right charge laptop battery?

Majority  of people think that it is unnecessary to wait for charge the laptop battery until it  automatically shutdown, and arbitrarily charge is not good. Generally speaking,most of laptop users are used to recharging the battery when the laptop has a charging indication .the time of indication for charging the battery could be set by user themselves ,with a common time is 3%.

I agree with the majority of the people. In fact, regardless of laptop use nickel-metal hydride or lithium batteries, these batteries have a memory effect. The memory effect of nickel-metal hydride batteries is very obvious, while lithium ones equally have memory effect, memory effect of which is smaller than the nickel-metal hydride bale.As for the totally misleading opinion that there is no memory effect on lithium, it is only exaggerated and irresponsible business conduct in advertising. Well, since the battery has a memory effect, it should be noted when charging .Charging it when the electricity of battery is completely run out as much as possible . Do not have to deliberately charge the battery until the laptop automatically shut down, although there is no harm (because the laptop battery has a charge discharge protection and automatic shutdown in general has not yet reached notebook battery discharge protection standards) In fact, to charge the battery when its power is less than 3%  is very good,  there is  certainly memories effect . Compared to natural wear and tear, it is ok. it is unrecommended to arbitrarily charge as the user wish . Whether  thelaptop battery is nickel-metal hydride or lithium,it has a memory effect.therefore,arbitrarily charging will greatly shorten the battery life.

Panasonic decides to reduce stake in Toyota hybrid-battery JV

The Yomiuri Shimbun reported in its Thursday morning edition that Panasonic (6752.TO) has decided to reduce its stake in a hybrid car battery-making joint venture with Toyota Motor Corp. (7203.TO) without citing sources.

The paper said Panasonic's planned merger with Sanyo Electric Co. (6764.TO) would give a market share in nickel hydride batteries of around 80% to both parts .What is more, Panasonic has decided to reduce its share in

Shizuoka prefecture-based Panasonic EV Energy Co.so as to speed merger approval from ongoing anti-trust investigations in the U.S. and China.

Panasonic currently holds 40% of the joint venture, with Toyota holding the remainder. How much Panasonic would sell is still unvealed.

A similar move was made by Sanyo yesterday that they announced to sell part of its battery operations to Fujitsu Ltd. unit FDK Corp.

shake to charge

The advantage of rechargable battery is that it could be used for many times after recharging,which is much more environmental friendly than general one. However,this hand-rechargeable batteries can be more environmental friendly than average rechargable batteries. It could be recharged by general charger, what is more, it could be charged jusy by hand without requing any other additional components.This AA-size nickel metal hydrate battery is composed of five components: a nickel-metal hydride rechargeable batteries, drive shaft, line tube, permanent magnet, and rubber shock absorbers.The battery capacity is usually half of that oridinary AA size , the electricity of which is mainly generated by lines. When the battery is shaken, the permanent magnet along the shaft and the center line of cylinder moving up and down to generate electricity. The rubber block is used to absorb vibration, at the samee time to help magnets bounce back. When we are away from home, or meet some emergency without electricity,we could make full use of this hand-rechargeable batteries to geberate electricity. If the integration of solar charging function were applied, such a battery could  be made into a variety of shapes, and then widely used in mobile phones, laptops, digital cameras and other electronic products. The prospect of this new hand-rechargeable batteries is very promising.
