VRLA battery charge balance principle of VRLA batteries (hereinafter referred to as valve-regulated batteries), with savings on investment, easy installation, safe, reliable, easy to use and other characteristics of the actual valve regulated Lead batteries (hereinafter referred to as valve-regulated batteries), with savings on investment, easy installation, safe, reliable, easy to use and other characteristics, in practical applications are widely used. VGP-BPS8，VGP-BPS8A , However, a lack of understanding of their application requirements, and follows the old balance charging system, batteries and cause great harm.
1. Reason cancel the equalizing charge
(1) What is a balanced load
The so-called load balancing, the battery characteristics of load balancing is currently using the battery as individual differences in the battery, the temperature differences cause an imbalance in the battery voltage terminal, the tendency to avoid the deterioration of this imbalance needs to improve the battery charging voltage group, the activation of the battery.
(2) no reason to even load
First, the concept of the concept of a balanced charge in lead acid batteries to the former using the most current valve-regulated batteries are clearly stated, “the balance of power in depth.” And “do not in the level of battery acid, without the need to balance the load.” For single battery charge voltage of 2.4 V is defined as the accelerated charge, that “FASTCHARGE” not “equation”.
Secondly, the balanced-regulated battery charging valve causing damage. voltage equalization charge for the majority of batteries are higher float voltage. At this point, most normal cells are in a state of overload. Gas in the battery can not be combined in a certain pressure, the pressure above the threshold valve, the valve opens, exhaust valve control.laptop battery
In the previous battery care, balanced with a battery charging process is performed to adjust the proportion, this approach by adding distilled water to add water to keep the battery in the balance. However, maintenance-free batteries, maintaining the current system is without water, this way will inevitably cause the battery to water loss, the dry battery.
2. After the cancellation of a balanced load, how to ensure the consistency of the voltage at the battery terminals PC764，Latitude D620 battery
(A) voltage across the battery of the decisive factors
Firstly, it is dependent on the concentration of the electrolyte and electrode materials. cell dehydration, electrolyte concentration must increase to increase the battery terminal voltage. Next, open the safety valve. Such as the low pressure safety valve, will inevitably lead to the premature loss of battery water, increasing the voltage of the terminal. In addition, the serial connection between the battery status is different, and the float, the load is insufficient. When the battery is full recovery from deep discharge of the extra load, it is difficult to reclaim, causing the voltage across the battery is low.
(2) means the voltage at the battery terminals to ensure
Since the battery voltage is inconsistency does not allow the battery to balance the load, so how to ensure consistency of the voltage at the battery terminals? First, the battery must be raw materials, production processes to ensure consistency in the battery voltage. Choice materials such as batteries, particularly the electrolyte plate, pressure regulators and other key materials selection. Secondly, we must ensure that the quality of the battery installation, the installation status of the battery to ensure consistency. For example, the method of connecting the battery torque balance, and so on. In addition, we need to be concerned about the maintenance.VGP-BPS2，VGP-BPS2A , For one behind the battery must be restorative, but also the appropriate adjustments battery electrolyte must regularly check the pressure valve in operating condition.
