General information about the battery

Designation

Located on the battery contains technical data. For example: 12 66 A / h to 200 A (12 V - rated voltage 66 A / h - nominal capacity, 200 A - Control discharge current cold).

Rated voltage

For all models, the total voltage of 12 V. The operating voltage depends on the battery charge and can be lower or higher than the nominal.

Rated capacity

Battery characteristics indicating amount of energy (A / h). It reflects the amount of energy which gives a fully charged battery at 27 ?� C for 20 hours under the condition that the voltage drops below 10.5 V (discharge voltage). With the onboard 12 V amperage from the battery is 2.08 A in accordance with formula

A (current) = W (power) / V (voltage)

Thus, the battery capacity of 66 A / h theoretically will provide a side light lamp power for 30 hours. In practice, if you leave the car with the lamps, the battery is discharged after 15 hours. Included alarm drain your battery in about 8 hours.

Capacity

To give the amount of electricity in the A / h. It depends primarily on the discharge current, ambient temperature, state of charge of the battery and the general state of the battery (the term of the operation).

Controlling the discharge current in the cold

Determines the ability of the battery to start up the engine at negative temperature (measured in A). A specific discharge current, taken from the battery voltage of 12 V at a temperature of -18 ?� C, provided that the voltage does not fall within the first 30 seconds, less than 9 V for 150 seconds - less than 6 V.

Self-discharge

Chemical processes inside the battery are responsible for self-discharge even when not connected consumers. A charged battery loses daily about 0.5% charge. Heat damage and pollution of its battery cover accelerate self-discharging.
