When you try to start the engine, the starter almost does not turn? Are the headlights flickering dimly? Car won't open with key fob? Congratulations! You've run out of battery. If the ABA at the same time is still swollen, or covered with an insoluble coating, or a crack has formed in its case, then such a battery can no longer be restored. In all other cases, the battery can be revived by charging. In addition, you can try to urgently start the car using one of the methods.
1. Lighting and starting
If you have good starting wires, as well as a kind soul who agrees to help you, then you can “light up” the car. 5-10 minutes of energy transfer should be enough to spin the starter once and start. If the matter takes place in the garage and there is a charger, the same can be done from a 220-volt outlet.
2. Tug and pusher
Both towing and pushing the car can, with good luck, take over the function of the starter and spin the crankshaft. The main thing to remember is that such a "grandfather" method is only suitable for "grandfather" cars. Namely, for cars with a manual transmission. You can't do that with an automatic transmission.
3. Hot water
If it happens in winter in severe frost, then you can remove the battery and lower it into a container of hot water. If you're lucky, this manipulation will allow you to warm up the battery and give a little more energy for a start for a short time. “Bathing” the battery will take about 30 minutes. It is also worth remembering that the method will work if the battery was not completely discharged.

4. Launchers
Capacitor or injection boosters connected to the battery may allow the battery to start. The people called these devices the unpretentious word "launchers". They connect directly to the battery. You should not go and buy "starters" for the cigarette lighter - this is a waste of money. The only disadvantage of such devices is the exorbitant price.
5. Terminal cleaning
Finally, do not forget that the problem with the lack of start may not be in the battery, but in the terminals. If they are covered with a layer of oxides, then they may well cause a car not starting. Recognition of oxidation is not difficult. All you have to do is clean the terminals with the right tool.
If you want to know even more interesting things, then you should read about what to do if the starter of the car does not turn well in the coldand the car won't start for a long time.
