Accumulator battery

Battery - a device for storing energy in chemical form which can then be used as electricity.

Rechargeable battery operated because two different metals, being in an acid solution, a potential difference, whereby the electric current.

1. On cars set free batteries.
2. The battery is not required to refill the distilled water.
3. The battery is completely sealed except for the small ventilation holes in the lid.

Inspection of battery

PERFORMANCE ORDER

Turn the ignition and all consumers of electricity. Disconnect the battery. Negative wire must be disconnected first, and connect the last. Remove the battery from the vehicle. If the case has been damaged the battery, remove the battery rubber gloves to protect your skin from the electrolyte. Check fasteners batteries, as they may be damaged by hitting on their electrolyte. If necessary, clean them with warm soda solution. In the same solution, clean the top of the battery. Inspect battery for cracks. If there are cracks, replace the battery. Clean the battery terminals. Clean the inner surface of the clamp wires connected to the battery terminals. Install the battery in the car. . Connect the wires to the battery terminals. Tighten the mounting clips of wires to the terminals of the battery. Coat the battery terminals a thin layer of petroleum jelly.

When charging batteries, an explosive gas mixture is released. When working with cables and electrical devices is forbidden the use of fire, sparking devices open by fire-dangerous light devices and smoking. Avoid sparking when handling cables and electrical devices. Never short the battery terminals directly - there is a great risk of injury due to heavy arcing.

Test Battery

Check the specific gravity of the electrolyte

Specific gravity of the battery electrolyte varies with temperature. Increasing temperature leads to a decrease of the specific weight and vice versa.

The proportion of the electrolyte fully charged battery should be between 1,260 and 1,280 at a temperature of 26,7 ?� C.

Adjustment of specific gravity should be carried out by the addition of 0.04 points for each above 5,56 ?� C temperature of 26,7 ?� C or subtracting 0.04 points for every 5,56 ?� C below the temperature of 26,7 ?� C.

For example: Indications hydrometer - 1,280 at a temperature of 5.56 ?� C. In accordance with the difference in temperature, adjust the specific gravity of 0.028 points. The true specific gravity of 1.252.

1,280-0,028 = 1,252

Do not measure the specific gravity of the electrolyte immediately after topping up with distilled water.

The difference in the specific gravity of the electrolyte 50 or more points between the banks of the battery indicates that the battery is faulty and should be replaced.
