Once when I was away on a business trip for a month without driving, the car wouldn't start at all upon my return. After checking, I found the battery was completely dead. Car batteries naturally discharge when left unused for long periods, especially during winter when low temperatures accelerate power loss. Now I use a smart charger to top up the battery weekly to maintain its activity, or alternatively, I start the engine and let it run for a few minutes each month to recharge. It's also recommended to check the battery terminals for chalky corrosion, clean them, and apply petroleum jelly to prevent oxidation. The anti-theft system and onboard computer also consume power - if parking for several months, disconnecting the negative terminal can save trouble. Purchase a small voltage tester; when readings drop below 12.4 volts, it's time to recharge.
