Скачать или смотреть How Long Should a Car Battery Last Without Driving

A car battery’s ability to last without driving depends on its chemistry, age, charge level, and storage conditions, with self-discharge and parasitic drain from electronics slowly depleting it even when parked. New AGM batteries in mild weather may hold enough charge for up to three months, while older flooded lead-acid batteries in extreme cold or heat can fail in as little as two weeks. Cold reduces cranking power and risks freezing if the voltage is low, while heat accelerates self-discharge and corrosion; age and partial charge also make batteries more vulnerable to permanent sulfation. Gasoline and diesel cars rely on 12V batteries for starting, while EVs and hybrids mainly risk 12V depletion despite their larger lithium-ion traction packs lasting months to a year when stored properly. To extend battery life, fully charge before storage, use a maintainer or disconnect the negative terminal, store in cool dry conditions, and monitor voltage regularly. Warning signs of depletion include slow cranking, dim lights, reset electronics, or low-voltage alerts, with proactive care helping prevent premature failure.
