Installing a battery on a car requires compliance with some nuances and features, ignorance and failure to comply with which can damage the car's electrical equipment and the battery itself.
Necessary
- - battery;
- - a set of keys and screwdrivers.
Instructions
Step 1
Make sure that the new battery complies with all the requirements and recommendations for the installed batteries set forth in the technical documentation for the car. In particular, the capacitance, the place of installation and the method of fastening, the polarity, the configuration and the dimensions of the collector elements must be appropriate. Failure to comply with the manufacturer's conditions will severely shorten the life of the starter and battery.
Step 2
Before installing the battery, clean it from dust and dirt, wipe the cover, terminals and contacts to remove oxides. Remove the plastic wrap from the new one. Use a soft cloth with soda water or ammonia solution to clean the housing and lid. When cleaning the case along the way, check it for integrity. Make sure the flue gas vents are open and clean. Check the electrolyte level in the batteries and top up with distilled water if necessary.
Step 3
Install the battery in its original place, tighten the retaining plate retaining nuts. In this case, the installation must be rigid, without backlash at the attachment points. Connect the wires after stripping the tips of the wires themselves. Lubricate the clamping nuts of the terminals with a special anti-oxidation grease and tighten with sufficient force. When finished, check again that the contacts are connected correctly.
Step 4
Install a new battery at an ambient temperature of at least 25 degrees. If it is winter outside and the car is parked in an open parking lot, bring the battery home, heat it up, charge it and then install it. If the battery is installed too close to the exhaust manifold, it may affect battery life. Provide thermal protection for the battery if not provided by the manufacturer.
Step 5
When installing separate dry-charged batteries into a damaged battery, pre-fill them with electrolyte and check the condition. To do this, unscrew the plugs on them and fill the body with electrolyte through a glass funnel to the maximum level. The density of the electrolyte should be equal to 1.28 g / cc. After sustaining a 20-minute pause, measure the voltage, which should be at least 12.5 V. At a voltage of 10.5 to 12.5 V, charge the battery. If the voltage is less than 10, 5 V - replace it. Recheck the electrolyte level and top up if necessary to the maximum level.
