Here you can play requires the passage of this site is definitely the old page that I have done and what has the most improvement Subba. Those that also binds the majority of visits. I will describe below HIM attractive options that you have your battery nickel and consequences of each load.
We flow of goods
The Dell 17 battery is nickel-consciousness is a constant voltage to participate with less than the minimum available at 1.45 V (Ni-Cd) to 1.6 V (Ni-MH) connected component. Following the minimum voltage of the battery is fully charged. The current must be maintained for some time (even if the gun), the performance depends on the load current and load rate.
The Prince is the battery to confirm the amount injected amount of current that reaches the capacity of the battery.
The rule is:
Q = I x T x ρ
(I Will Be aware of constant load, the load time t, ρ is the charge Q will return and the amount of electricity or the battery capacity).
We return ρ in imports of a fluctuating value of the insurance. Depends mainly on the speed and cost for most. But he also Varirata function of temperature of the load in the structure and age of the Dell 1737 battery. The values you give me in this document should be taken to a result with an error message of tolerance is at least 20%. Sorry could not be better.
DURING the charging voltage of the first battery is constant increased rapidly marking and much more in a canopy tension. Increased tension until finally a maximum voltage. And "the increase in blood stopped. Charging is complete.
To as the battery (Asus PC 900 battery)that comes with the same power draw: There are overloaded. If the battery can store more energy, it has all the power is released in spas. The heating element. There, at that time the production of oxygen and hydrogen elements. In terms of current tax claims that have been created, and how you know that the memory effect is small, but if you know that a partial destruction of filling. The elevation of the flow temperature reduces the internal resistance of the battery light and a slight drop in voltage due to the battery terminals. This is the peak of blood to be known as Delta or Delta-V or DV -dV/dt Mathematically it is a change in the slope of the load. Derivative of the curve is negatively charged.
See all information here delta peak
It's time that the dell 1564 battery voltage until the maximum is reached when the decline begins and excitement. The recommended method is to speed fast and high taxes. Other solutions are possible.
It is also often used:
The detection of stress at the end theoretical charge (1.4 V / cell)
The temperature increase depends.With a little "inflection point" ahead of the curve just before the income tax: the V d ² / dt ².Groups in a single payment for the theoretical exercise of the Asus PC battery.
The amplitude of the variation of the peak of the delta is the change in internal resistance and therefore the change in temperature. Temperature changes in the value of the loading rate, taking over the load current. The internal resistance of the Ni-MH is higher than that for Ni-Cd exothermic, the reaction of Ni-MH, while endothermic on Ni-Cd, changes in voltage at the end of treatment is much higher in Ni - Cd Ni-MH. This makes the detection-dV / dt Ni-MH difficult or impossible for the minimum load current. And the "best when it recognizes ² / dt ² longer visible, or Dell M1210 Battery will be sufficient time to load.
The yields of different speeds and loads
The normal load
You should know that only cost is the rate recommended by the manufacturer for a better life for nickel the constant current is equal to the rated current of 1:10 to provide. We call this the cost of normal load (not the slow loading said in the Ni-MH). This is the percentage of power for all tests of nickel batteries, including the speed, the body's ability to display the battery(Dell E6410 battery), known rated capacity used to measure.
This is the rate of loading, which ensures long battery life.
The tax is normally at a rate of C/10 with a yield of about 0.7
Thus, for about 14 hours.
At this rate:
- The Delta Summit is Ni-Cd, Ni-MH, but difficult (based on observed after ....)
- The head is not destructive but creative memory effect.
Yellow line
The accelerated charge
And "carried out in a steady flow of a value equal to 1 / 5 of rated current. At this rate, C / 5, the additional cost is for NiMH and no more than 40 minutes to Ni-Cd, under threat the destruction of the elements. This post is quite fast, but inferior to a normal shop. The battery can not keep 100% of capacity would be to take a normal load.
The charge is accelerated at a rate of C / 5 with a yield of about 0.8
For example, 6 hours and 30 minutes.
At this rate:
- The delta peak is observed for both technologies.
- Transparent to the elements (accelerated erosion) is amended.
Yellow line
Prompt payment
And "carried out in a constant current with a value equal to the nominal current of overcharging. It is forbidden to charge fees. Be careful not all batteries, the type of tax, including the specific battery "weight" and "mainstream" low-end. Fast-charge of inferior quality. The SONY VGN-FZ460E battery can not keep 100% of the capacity to carry a normal load. Moreover, this type of load is to change the batteries. constantly uses Fast Charging the battery life decreases very visible.
With the rapid transfer fees against Ni-MH "drive" of high currents from the battery. Then you can load all the means at the internal resistance of Ni-MH regression.
The fast charge 1C with a yield of about 0.95
So about 1 hour 05 minutes.
At this rate:
- The Delta-peak is very well recognized by both technologies.
- Congestion is destructive elements.
Yellow line
Ultra-fast charge
And "carried out at constant current with a value of 2 or 4 times the rated current of overcharging. Is absolutely forbidden to charge fees. WARNING only the best support this type of battery. Fill the air cells cool for this type of tax. The ultra-fast battery is too low for energy / stored. Also record what type of exposure is very taxing on the battery. consistently uses rapid charging drastically the lifetime of the batteries reducing .
Compared to the controller provides UTRA Ni-MH Rapid "guide" of the aspire 1410 battery to carry very high currents. This type of support can reduce the internal resistance of Ni-MH. This model is used for batteries to power electric motors.
The charge is super-fast rate of 2C with a yield of about 0.98
So for 30 minutes.
The temperature factors are controlled and cooled during charging.
A safety timer, in case of detection of the delta peak will be available.
At this rate:
- The delta peak is detected very well with both technologies.
- Expenses are very damaging to the elements.
Yellow line
The dead weight
And "with a constant current to a value equal to the nominal current of the battery for an indefinite period of time (: or at least not one week) leads 1/20th. The battery is charged, but not dangerous warming of the end of the load (low current).
Weight is at a rate of C/20 with a yield of about 0.5
Thus, for at least 35 to 40 hours.
At this rate:
- The peak is barely detectable in Delta Ni-Cd and Ni-MH is not at all.
- Overhead is the memory effect, but inofensive creative.
Yellow line
The ongoing maintenance
A battery (Dell E1705 Battery)tends to discharge naturally. After a charge of maintaining a constant flow with a value of 1/50th to 1 / 100 of rated current for an indefinite period on the state of charge for up to keep. This power is not actually charge the battery, it is only natural losses offset.
Please note that this type of maintenance (trickle in English) is a small creative memory effect.
Entetien the current can be used to load, which began in the early months of full payment.
Yellow line
Loads of attention faster and faster, if you do not meet system load detection and automatic shutdown after the end of the year (-dV/dt) The battery must be discharged before charging is essential. Ultra-fast charge the final AquaStop is essential.
Fast and good quality
The Dell Mini 12 battery fast charge is damaging the batteries. The most dangerous are the initial stages of loading (chemical load early) and the end of exposure to the risk of overload. There is a solution for the creation of a rapid charge of security. This method consists of three phases.An initial load flow to start charging quickly when the elements are very relieved.
The main load support in a hurry or to fill the battery.An additional cost of routine maintenance to determine the end of the fast charge.
This ensures the battery charged to 100% in a relatively small.
The initial charge is determined by the -dV/dt (voltage) or dT / dt (temperature) was observed. A variant, which stops the loading of a "just before the end of the charge, showing ² / dt ² (for very strong currents).
With this rule in danger of overload, but there are still safety timer (timer) that the tax cut that the theoretical maximum time allowed.
