Compared to the other parts of laptop, the battery and charger seems to be more sensitive while users need to have some proper ways to charge the batteries while the usage frequency, lifespan and recharging cycles are the important factors to influence on the battery and charger.

Nowadays, the lithium-ion batteries have covered nearly all the market while they have certain recharging cycles and lifespan. Generally speaking, the HP dv2500 battery needs to have some power energy inside and the manufacturers have already got some activation and pre-charging before leaving the factory. As for the original ones, fully charging and discharging is necessary and users need to have some operations on it to complete a whole cycle.

As for some fast charging adapters, when the indicator is transferred to be charged to about 90%, the charger will slow down until it is full. Users had better select the suitable and smooth charge ones to extend the lifespan and life time. Meanwhile the chargers from good suppliers and manufacturers are good choices.

Actually, charging when the laptop is on is of a little damage to the battery and charger lifespan. In the process of charging, the internal circuits will increase in work temperature while the output current is possible to be damaged suddenly. Therefore, it is properly to have suitable work situations for laptops and look for a special outlet for batteries to charge.

And some warm-hearted users have published some simple methods in Apple customers supporting forum, including fixing disk access or access control form, forbidding or re-stalling Dropbox application, reseting GateKeeper enabling program from any sources to against this problem. Although some users have fixed the problem by adopting above methods, most users still claim that the problems cannot be fixed. So some users presume the problem maybe between security and file system.

A user from Apple customers supporting forum claimed that he had gotten in touch with Apple. He said the influence of battery performance after upgrading Mountain Lion is no relationship with hardware and battery itself. The major problem is due to the software platform. In addition, he said Apple would release an updated in App Store recently to help users to fix this problem. But this news has not been proved by Apple. So the users who are puzzled with this problem have to wait for the further news.

In 16th, Auguest, City Labs in Florida has released the first Tritium battery in the world which called NanoTritium battery. It is an amazing lifespan reached to as long as 20 years. As we all know, normal lithium Dell Latitude d820 battery usually has 2-3 years working time. So 20 years for long life span is actually unbelievable event we have ever met.

Let us get a rough idea with this groundbreaking scientific achievement.

tritium battery

1) Principle
Tritium is one of the isotopes with hydrogen which has radiation. It is including two neutrons and one proton. And its atom is not stable so it could be decayed into helium which owns three protons.
IT will release abundant electron which can offer power to machines during the decaying process. That is the principle city Labs take advantage of to make the NanoTritium battery. Although Tritium has radioation undeniably, the quantity is very tiny. It could not do any harm to human body.

2) Advantage
Compared with the widely used batteries, the durability of NanoTritium battery is much stronger. It can endure the temperature from Minus 50 degrees Celsius to 150 degrees Celsius. Otherwise, its ability in anti-pressure and anti-shake is also very excellent.
Above all, the biggest advantage of NanoTritium battery is its long lifespan. It could be lasting 20 years which outdistances the average lifespan of batteries nowadays.

3) Security
Tritium has definite radioaction but it is very tiny. That will not cause any harm to human being at all.

4) Current usage
The new NanoTritium battery is priced $1000 for sale. It is under voltage 2.4V, 50~350 nano amps current. The maximal power is only 840 Nevan. That indicates it cannot be put into used to mobile phone field.

But it can be used in some small electronic equipments like watches, audiphones and cardiac pacemakers. It is undoubted that with the development of Tritium batteries, the problems which puzzle people in mobiles phones and laptops will be solved in near future.

Is it necessary to take out the laptop battery when AC adapter is plugged in? Actually lithium ion batteries have approximate 500 times volume for being charged and discharged. The lifespan of batteries is exactly related to the frequency of charge and discharge.

If your laptop which has Sony vgp bps8 battery inside is plugged and unplugged into the power supply several times within one day, that do more harm to your battery. Because connecting with the external power supply each time is equivalent to charging the battery one time, therefore that could be also consume its working life.

Consequently, you had better take out your battery if your AC adapter is plugged in, which will prolong the lifespan of your battery.

We can analysis the situation your laptop meets when your AC adapter is plugged in the external power supply.

Because of the laptop computers charging protection circuit function, battery inside can maintain in 95% ~ 100% of full power state. Meanwhile, the environment temperature of battery could be at least 25-30 degree centigrade. In addition to this, the temperature would be much higher in summer. The conclusion you can easily get from above is that plugging AC adapter with the battery inside will harm the battery badly. It causes its capacity down memorably. The consequence is your battery will die quicker because it is under the bad circumstance always.

In other words, it still runs a little risk for plugging AC adapter only without battery inside. That may hurt the hardware of your laptop if outage suddenly or voltage instability. But it is not necessary to care so much as it seldom happens.

So we suggest that please take out the battery from your laptop under the situation that the power supply is stable. And backup data from time to time in case the external power supply is cut.
