How to choose an acid battery
How to choose a car battery foroperation to minus 30 degrees in winter and plus 30 degrees in summer. We buy in the store or take from hand an old one with no guarantees. My practice shows that you can choose a good battery. We need a proven good battery.
Car batteries serviced or notserviced, have the same electrical parameters. In this case I'll describe how to choose 6st55. The life of the battery begins as soon as it is filled with electrolyte. In the battery after pouring is a process of self-discharge and is equal to two percent per month from its capacity. Therefore, the year of release should be fresh. The main factors are instrument measurements. In specialized stores, the consultant's seller has all the appliances. Therefore, be sure to ask to measure the battery with devices. The first is to measure the voltage in volts, where the device should show 12.72 volts. Pay attention to 12 whole and 72 hundredths of a volt exactly hundredths show that the battery is fully charged. The open circuit voltage or idling is 12.72 volts - a good indicator. The next step is to measure the battery with a load plug. The load fork creates a current equal to the starter and simultaneously shows the voltage. The device on the load fork should show at least 11.5 volts - the battery is good. If less than 10 volts - you should not take. The main thing to remember is the voltage of the open circuit 12.72 volts. Where at the start-up of the car at the terminals of the battery is not less than 11.5 volts. There is still another step to inspect the battery for cracks, scratches, various dents on the body. The battery must be dry on all sides. If you take an old battery, then the electrolyte should be clean, if the electrolyte is dark or dirty - this will lead you on the road. Perhaps the most important thing to observe safety when working with electrolyte.
