General recommendations
The car can be equipped with both a serviced type and an unattended type of battery. As a rule, the service life of a maintenance-free battery is set by the battery manufacturer, and there is no need for frequent checking of the electrolyte level during its operation. The design of the maintenance-free battery does not allow the addition of electrolyte, so if the level drops below the acceptable level, it is necessary to replace the battery with a new one.
When choosing a new battery, you must be guided by the parameters for the battery, which the manufacturer presents specifically for your car.
Battery parameters:
Capacitance, measured in Amp-hours (Ah). This is the amount of electricity that can be obtained from the battery when it is discharged to the set final voltage
Cold cranking current is the amount of current supplied by the battery to the vehicle's starter during a cold start. Measured in amps (A).
The size of the battery case must correspond to the dimensions of the installation site, and the mounting brackets. On the vehicle, the battery must be securely fixed in place.
The parameters of the battery, as a rule, are indicated on its case. However, different manufacturers use different standards for measurement, and therefore it is necessary to take this into account.
Vehicle check
- Recommended battery - 75D26FL 75D6LL, 95D11R
Attention:
- Do not disconnect the battery while the engine and/or accessories are running. Turn the ignition key to position "OFF" (LOCK) and turn off all additional electrical equipment.
- When checking, disconnect the negative battery cable first and reconnect it last.
- Be careful not to short the terminals with tools.
1. Visual check of a condition of the accumulator battery.
Note: If there is corrosion from the electrolyte, wash the damaged areas with a solution of clean warm water and soda, then wipe dry with a cloth. Do not allow cleaning solution to enter the battery.
A) Check the racks and battery tray for corrosion damage caused by possible electrolyte leakage.
b) Check the battery case and cover for cracks or damage that could cause electrolyte leaks. Replace the battery if necessary.
Attention: if there are electrolyte leaks from the battery, use suitable rubber gloves when removing the battery (do not use household gloves).
V) Check the strength of the fastening of the battery terminals. If the terminal connections are loose, tighten the retainer nuts.
G) Check the terminals for damage and corrosion, clean the terminals if necessary and apply special grease to them.
Caution: Do not overtighten the terminal clamp nuts.
d) Tighten the clamp just enough to securely hold the battery in place. Overtightening may damage the battery case.
2. Check the amount of electrolyte in each battery cell. If the level is below the mark "LOW" That:
(Serviceable battery) Top up with distilled water. After adding water, charge the battery.
(Maintenance free battery) Replace battery.
2. (Serviceable battery) Check electrolyte density.
- Nominal density (at 20°C) — 1.25-1.29 g/cm3
If the density of the electrolyte is less than the nominal, then charge the battery.
3. Measure the battery voltage.
A) The check is carried out at the end of the movement of the car and no later than 20 minutes after the engine stops.
Turn on the ignition ("ON") and electricity consumers (headlights, fan, rear fog lights) for 60 seconds to remove the surface charge,
b) Turn off the ignition ("OFF") and consumers of electricity, measure the voltage between the negative (-) and positive (+) battery terminals.
- Rated voltage (at 20°C) - 12.5-22.9 V
If the voltage is less than the nominal voltage, charge the battery.
(Rechargeable battery with state-of-charge indicators)
Check the status of the indicators according to the battery manufacturer's instructions. The colors indicating the state of charge of the battery for each manufacturer may differ from those shown in the figure.
- Blue: The battery is OK.
- White: Recharging required.
- Red: Insufficient electrolyte level.
4. Use a tester to check that the fuse links are in good condition, making sure that there is conductivity (short circuit) on their findings.
A) Check the strength of the fastening of the battery terminals, the absence of corrosion,
b) Check the integrity of the fuse and fuses.
5. Charging the battery.
Note: Please read the instructions for this charger before charging the battery. Carry out charging strictly according to the recommendations indicated in it.
A) When charging a battery installed in a vehicle, first disconnect the cable from the negative battery terminal, and then disconnect the cable from the positive terminal to prevent damage to the vehicle's electrical components.
b) The charging current is usually 1/10 of the battery capacity. Charging time depends on battery type and capacity.
Note: in case of fast charging (due to lack of time, etc.) battery, the charging current should never exceed 70% of the battery capacity indicated in amps, and the charging time should not exceed 30 minutes.
G) Determination of the end of charging:
- If the density of the electrolyte has reached a value of 1.25 - 1.29 and remains constant for an hour.
- If the voltage of each battery cell reaches 2.5 - 2.8 V, I remains constant for one hour.
Attention:
- Be careful to keep an eye on the electrolyte level, which may rise during charging.
- Do not charge near sources of fire due to the risk of explosion.
- During charging, do not carry out work nearby that may cause sparks.
- After charging is complete, close the lids of the jars, rinse the outside of the battery with clean water to remove acid residue and wipe dry.
Removal and installation
Caution: When removing and installing the battery retainer, do not allow it to come into contact with both battery terminals to avoid electric shock.
1. Remove the parts in the order they are numbered in the figure.
1 - wire from the negative terminal,
2 - wire from the positive terminal,
3 - latch,
4 - battery,
5 - battery tray.
2. Installation of parts during assembly is carried out in the reverse order of removal.
