What battery is on Lada Largus?
A battery with reverse polarity is installed on a LADA Largus car (the negative terminal is facing the left side of the car, and both terminals are located closer to the windshield, see photo below). Rated capacity at 20-hour discharge mode is 70 Ah.
The battery is not serviced, there are no traffic jams in it. The degree of battery charge can be determined by the color of the indicator mounted in the battery cover: – green color means that the battery is charged; - dark color - partially discharged; - a transparent or light yellow color indicates a decrease in the electrolyte level in excess of the permissible level.
Precautionary measures
Sulfuric acid solution is a very corrosive and toxic substance that corrodes most metals, so the following precautions should be observed when servicing the battery:
- use safety goggles
- Wear acid-resistant gloves and acid-resistant clothing.
To prevent the battery from breaking or exploding, make sure there are no sources of heat or sparks near the battery during charging.
Insufficient tightening of the terminals to the battery can lead to heating of the contacts, malfunctions when starting the engine or charging the battery, sparks or explosion of the battery.
Attention. To prevent sparking when disconnecting the wire terminals from the battery, make sure that all electrical consumers are turned off.
At battery charging indoors, turn off the charger before disconnecting or connecting the battery.
Do not place metal objects on the battery that may cause a short circuit between the terminals.
Attention. The reliability of the visual indicator is not guaranteed by the after-sales service, so do not use the visual indicator as a means of monitoring the condition of the battery.
Removing
Place the car on the workplace, brake with the parking brake, turn off the ignition, raise the hood.
Attention. Before disconnecting the battery, you must:
- wait for the electric fan of the engine cooling system to stop;
- wait for the end of the procedure for saving data to the computer (1 min).
Remove the cover from the positive terminal.
Loosen nut 2, Figure 2-1, battery negative cable terminals (wrench "on 10").
Disconnect the negative cable terminal from the battery.
Figure 2-1 - Removing the battery: 1 - nut for fastening the positive wire terminal; 2 - nut for fastening the negative wire terminal; 3 - battery; 4 - battery mounting bracket; 5 - a bolt of fastening of a level of the accumulator battery
Loosen the nut 1 of the battery positive cable terminal (wrench "on 10").
Disconnect the positive wire terminal from the battery.
Unscrew the bolt 5 fastening the battery bar (interchangeable head 13, knob, extension).
Remove fastening bar 4.
Remove the battery.
Installation
Clean the battery terminals and wire terminals and apply a thin layer of grease on them, if there is a white coating on the terminals, remove it with sandpaper (vaseline technical VTV-1 in aerosol packaging, sanding paper with a grain size of not more than R 220 or felt with abrasive paste PMA-2).
Install the battery in the reverse order of removal.
In this case, the tightening torques:
- bolt of fastening of a level of fastening of the storage battery - 12 Nm (1.2 kgf·m);
- positive wire terminal bolt - 6 Nm (0.6 kgf·m);
- negative wire terminal nut - 6 Nm (0.6 kgf·m).
Make sure that the battery is securely mounted on the site.
Install the cover on the positive terminal.
