Advice 1: How to determine the battery charge

On the market sales are offered in most cases maintenance free batteries. This fact means that the unit is beyond repair and is designed for a certain period of operation without interference from the owner, and then disposed of.
You will need
  • - the charge indicator.
Instruction
1
Often come across batteries, which is impossible to access the banks. Top cover they are sealed, and distilled water in a battery impossible. The only way to check the level of charge in such energy storage devices is a visual inspection of the color indicator located at the top.
2
If the indicator is green, the battery is normal. The absence of a specified color warns about the need to re-charge the battery. The white color indicates that the level of the filled electrolyte is low and the battery needed topped up with distilled water.
3
Maintenance-free storage battery after occurrence of the white led is utilized. Serviced the battery open lid cans, and are easily restored.
4
In a lead acid battery topped exclusively with distilled water. The electrolyte is dilute sulfuric acid is strictly prohibited. Otherwise not to avoid destruction of the active mass to the lead plates.

Advice 2: How to determine that the battery is charged

Battery charging constant current of fixed value. And the charge process is the conversion of electrical energy supplied to the battery from an external source of current, chemical.

Battery: battery stops charging after it reaches a certain voltage. After the battery is fully charged, all energy coming to it exceeds its capacity. To get it, the battery has to give part of its energy, and recharge. This process has very negative influence on the device, quickly drained it shuts down. That's why determining the exact time of charge is very important.
2
Today, many batteries are equipped with a color charge indicators. They are located at the top of the device. To understand the condition of the battery, look at the color of the indicator bulb. The absence of color suggests that there is no charge, white color means low level, flooded with electrolyte, and the green shows fully charged battery.
3
There is a repaired and beyond repair batteries, differing ability to access banks with electrolytes. If the electric component box with sealed top cover illuminates the charge indicator white light bulb, you just have to throw it away. Nothing more you and he can not do. And in any case do not dilute the electrolyte with something else, especially sulfuric acid.
4
But to charge the repaired battery in this case you need to fill distilled water. To do this, lift the upper part of the unit, Unscrew the lid of the jar and add water to the required level. After that will just have to wait for fire green and disconnect the battery from the network.
5
In the absence of the unit of color charge indicator charge the battery more than 16 hours. To save the lifetime battery charge is not enough better than recharging.
