The battery works due to the fact that two different metals, being in an acidic solution, generate electricity.
The battery is 100% efficient at 27°C. At -18°C, the efficiency of the same battery drops to 40%. Now, in order to start the engine, it is necessary to have more than twice as much energy as was needed at 27°C.
starting power (starting amps) indicates the battery's ability to start the vehicle in very cold weather. It shows the number of amps that the battery produces for 30 seconds at -18°C without a voltage drop below 7.2 volts (the minimum level required for a reliable start). The higher this figure, the greater the starting power of the battery.
Standby capacity indicates the length of time in minutes that the battery provides 25 amps at 27°C. This factor represents the time during which the battery provides operation of all auxiliary devices in the car at night and in bad weather conditions with a faulty charge generator.
In winter conditions at -18°C and below, the battery will be poorly charged due to an increase in internal resistance. For short trips in winter, the energy used by the battery to start is not compensated. As a result, the battery wears out, constantly discharges and eventually fails.
During the summer months, after long trips, the engine becomes very hot and it often happens that it is difficult to start it again. Such "hot starts" sometimes require as much power as in cold weather, or more. This is especially true for large displacement high compression engines and air-conditioned vehicles. This once again emphasizes the importance of choosing the right battery according to the vehicle's engine.
Warning: It is necessary to work in protective glasses. Do not allow droplets of acid and particles containing lead compounds to come into contact with eyes, skin or clothing.
Warning: The electrolyte is very corrosive. Use protective gloves and goggles. Do not tilt the battery as electrolyte may spill out of the vents. If electrolyte gets into your eyes, immediately flush your eyes with clean water for several minutes. After that, contact your doctor immediately. If electrolyte comes into contact with skin or clothing, immediately neutralize the acid with alkaline soap and wash the affected area with plenty of clean water. If electrolyte is ingested by mistake, consult a doctor immediately.
Warning: When batteries are charged, an explosive mixture of gases is released.
Warning: When working with wires and electrical appliances, the use of fire, sparking devices, open flammable light devices and smoking is prohibited. Avoid sparking when handling wires and electrical devices. Never directly short the battery terminals - there is a great danger of injury due to strong sparks.
Before carrying out any work on the vehicle's electrical system, disconnect the negative cable from the battery. When replacing incandescent lamps, it is enough to turn off the corresponding switches.
When disconnecting the battery from the car's on-board electrical system, first disconnect the negative wire, and then the positive one. When the engine is running, the battery must not be disconnected, otherwise the electronic devices of the electrical system will be damaged.
When installing a battery in a car, you must first connect the positive wire, and then the negative one.
To protect the battery case from UV radiation, do not store the battery in direct daylight.
