What to Do When the Small Battery Runs Out of Power?

Take out the jumper cables and connect the positive and negative terminals of both cars respectively. Before connecting, first attach the positive terminal, then the negative terminal. After completion, first remove the negative terminal, then the positive terminal. After use, be sure to charge it promptly to maintain sufficient power to handle unexpected situations.
If the small battery runs out of power, don't panic. I think this is quite common, especially in winter when the cold weather drains the battery faster. You can first ask a friend for help to jump-start the car using jumper cables—connect the red wire to the positive terminal and the black wire to the negative terminal. If that doesn’t work, manual transmission cars can be push-started, but don’t try this with an automatic transmission to avoid damaging the car. The battery might die due to leaving lights on or an aging battery, so remember to check the battery’s condition regularly. Use a car charger or take long drives to recharge the battery as a preventive measure. A portable jump starter is very handy in emergencies and can be bought online for just a few dozen dollars. The battery lifespan is usually two to three years, and replacing it isn’t expensive—just a few hundred dollars. Proper maintenance can help you avoid such troubles.
I've experienced a dead small battery a few times, so I know some solutions. Priority is to call roadside assistance or ask a friend for a jump start to quickly resolve the issue—safety first, don't linger on the roadside. A dead battery is often caused by doors not being closed properly or corroded battery terminals that need cleaning. During daily driving, avoid frequent short trips that require starts and pay attention to the alternator's insufficient charging. Regularly check the voltage at a shop—normal is around 12.6 volts. For prevention, keep the battery box dry to extend its life by a few years, saving money and hassle. In emergencies, a portable jump starter is effective and convenient to carry—I've tested it myself.
Dealing with a dead battery by jump-starting is straightforward and effective. Simply connect to another vehicle, start the engine, and let the alternator charge the battery. The cause is often forgetting to turn off devices or an old battery—monitor voltage during maintenance; replace if it drops below 11 volts. Develop driving habits to avoid prolonged inactivity that drains the battery. After jump-starting, drive for half an hour to fully recharge.
