what is the battery internal resistance

The battery internal resistance is the battery at work,toshiba pa3285u-1brs battery the current flows through the battery received by the internal resistance, are generally divided into AC resistance and DC resistance, due to a small rechargeable battery internal resistance, the measured DC resistance when the electrode capacity due to a very technology, resulting in polarization resistance, we are unable to detect their true values, while the measured AC resistance can avoid the impact of polarization resistance obtained in the real resistance. AC resistance test methods are: the use of the toshiba pa3284u-1bas battery is equivalent to an active resistance characteristics of the battery a 1000HZ, 50m A constant current, its voltage is rectified filter and a series of sample handling, and thus accurately measure the resistance.
1, what is the standard anti-overcharge test?
IEC provides a standard lithium battery overcharge resistance test as follows: 1). To discharge the battery 0.2C to 3.0 V 2). With the current I arbitrarily set the 10V voltage on the battery charge, charge time is T = 2.5 * C5 / I 3). toshiba pa3465u-1brs battery explosion and fire is not the final
2, what is the short-circuit experiment?
Will be fully charged battery in the explosion-proof box with a wire directly connected to positive and negative, the battery should not be an explosion or fire.
3, what is the drop test?
After the battery is fully charged from three different directions on the 1m height fall on hard rubber plate in each direction, to do two times,toshiba pa3634u-1bas battery pack electrical properties should be normal, packaging without damage.
4, what is vibrating experiment?
Battery vibration test methods are: the battery to discharge 0.2C to 3.0V after the 1C charging, constant current constant voltage charging to 4.2V, cut-off current of 10mA, set aside 24 hours after the vibration according to the following conditions: amplitude of 0.8mm, so that the battery 10HZ – 55HZ between the vibration, toshiba satellite 2800 battery the vibration 1HZ per minute rate of increase or decrease, the battery voltage should be + / _0.02V between the resistance change in less than 5m.

the battery have any effect on the environment

the battery have any effect on the environment?
Today almost all the batteries are not mercury, but is still heavy metals mercury batteries, rechargeable nickel-cadmium batteries , lead-acid batteries of the necessary components. If disposed of improperly, and a fairly large number, these heavy metals have a harmful effect on the environment. At present, the international specialized agencies have been recycling nickel-cadmium and manganese oxide lead-acid batteries. Polymer batteries without liquid, zero-emissions, no heavy metals, won its green, environmentally-friendly laudatory. The ideal society of the future environmental protection energy products.
9, the ambient temperature on battery performance impact?
Of all the environmental factors, the temperature on the battery charge and discharge performance of the most influential, in the electrode / electrolyte interface, electrochemical reactions and environmental temperature. If the temperature decreases, the electrode response rate also dropped, assuming that the battery voltage is kept constant, the discharge current is reduced, the battery’s power output will fall. If the temperature rise on the contrary, that the battery output power will increase, the temperature also affects the transmission rate of electrolyte, the temperature rise is accelerating, transmission temperature drop, send slow down, the battery charge and discharge performance will be affected. However, the temperature is too high, exceeding 45 ° C, will destroy the chemical balance within the laptop  battery, resulting in side effects.

how can you care for your battery to get the maximum life out of it

Always use your laptop on a hard surface.
Laptops are portable and it's easy to set your laptop on your ibm thinkpad r52 battery or on your bed and use it at your lesiure. That's one of the benefits of having a portable computer. Flexibility. But if you want to extend your battery life you have to watch out for overheating your laptop.
Heat is one of the biggest obstacles to battery life longevity. Your laptop computer fan cannot circulate the air properly when your laptop is sitting on soft surface.
2.) Do not keep your battery installed when you use your laptop on AC for an extended period of time.
While your laptop is undoubtedly using a smart charger to charge your battery even a constant trickle charge over months can reduce your battery life. For best results, only charge your ibm thinkpad t41 battery when you need to charge it, don't leave the laptop battery plugged in all the time.
More importantly than the trickle charger affect is the 'storage' of a Li-Ion battery at elevated temperatures. The optimum storage temperature for a Li-Ion ibm thinkpad t61 battery is at 0 deg. C. The optimum storage charge level is about 40%. Unfortunately we tend to store fully charged and at the temperatures found in a running laptop you'll find a significant reduction in battery for your laptop performance after only 12-18 months.
3.) Use a full charge cycle before recharging
Li-Ion and NiMH battery (ibm thinkpad t61p battery), do not have a memory which you might find in NiCad batteries. However, each chemistry has a limited number of charge cycles, so use a full charge cycle before re-charging to maximize your IBM ThinkPad R52 Battery usage.
Because this may be very difficult to manage, you'll need to consider the cost-benefit ratio for keeping track of how far discharged the battery is before you charge it again.
4.) Be careful where you store your laptop
This goes back to the heat issue. Don't leave your ibm thinkpad x41 battery in the car where it can get very hot.Batteries hate heat and your battery will go on strike permenantly if you expose it to too much heat.
Remember that all laptops are not created equal. You may have gotten 4 hours from your last laptop while on laptop battery , but your new laptop might pull more juice to run that gaming quality processor, or the power hogging programs you're running now. Read your owner's manual to find out what you should expect from your laptop battery and be sure to compare apples to apples when purchasing a replacement lenovo 3000 c100 battery. Not all laptop batteries are made to the same specs. We recommend buying a battery that has at least as much capacity as your original battery (that's the mAh rating), and preferrably the same chemistry as well.
