Reasons Why the Battery Won't Charge

Gasoline has a very low flash point and ignition point, with a flash point ranging from -50 to -20 degrees Celsius, and an ignition point only 3 to 6 degrees Celsius higher than the flash point. Below is relevant information: Gasoline Shelf Life: Gasoline has a shelf life of about three months, as its active components are highly volatile. Gasoline stored for too long will inevitably have reduced combustible components. After exceeding the shelf life, the quality of the gasoline will deteriorate. Car owners can assess the quality of the gasoline by examining its color, smelling its odor, and feeling its texture. Gasoline Storage Conditions: Prevent the anti-knock performance of gasoline from degrading. When a car is parked for an extended period, the octane rating of the gasoline will decrease due to the loss of light components and an increase in gum content, thereby reducing its anti-knock properties. Therefore, the gasoline tank should be tightly sealed and kept away from high temperatures.
My car battery wouldn't charge at all the other day, really annoying. Generally speaking, this is probably just the battery aging, especially for cars that have been driven for several years, used infrequently or mainly for short trips. The battery's internal activity decreases, and excessive sulfide buildup leads to failure. Also, check the charging system - if the alternator is broken and not generating electricity, low output voltage will prevent charging. Corroded or loose terminal connections can also cause poor contact, blocking charging current. I've measured it several times with a multimeter - if the voltage is below 12 volts, that's suspicious. After severe discharge like leaving headlights on overnight, ordinary chargers can't revive a deeply discharged battery; special equipment is needed for reactivation. This situation is dangerous in daily use - breaking down on the road would be troublesome. I recommend going to a repair shop promptly to replace the battery or check the alternator, don't try to save money and let it become a bigger problem. It's best to check the battery condition monthly to extend its lifespan.
I love tinkering with cars in my spare time, and battery charging issues are quite common. Thankfully, experience has saved me a lot of trouble. The core issue often lies within the battery itself—like dried-up electrolyte or aging plates, which means it's time for a replacement when the lifespan is up. Charging system failures, such as a loose or worn alternator belt, can lead to insufficient power generation and failed charging. A simple method: measure the battery voltage at idle after starting the car; normal readings should be above 13 volts—anything lower indicates a problem. Corroded or loose cables and terminals are also frequent culprits; I usually start by cleaning the terminals. If a charger doesn’t help, the battery might be deeply discharged and require professional handling. Always remember to turn off electrical devices when parking to avoid excessive drain. Repairs aren’t too difficult, but neglecting them can affect startup and driving, especially in winter when issues are more likely to arise.
I've been driving for decades, and most cases of batteries not charging are due to daily neglect. The most common issue is the battery itself being dead, such as after five or six years of use, when the plates deform or internal short circuits occur, making normal charging ineffective. Problems with the charging system, like a non-functioning alternator, require checking by starting the engine and measuring the voltage. Corrosion at the connections increases resistance, blocking current flow—a simple wipe of the electrodes can fix minor issues. Additionally, a broken charger or incorrect usage, such as not securing the connection before charging, wastes effort. Over-discharge is common; forgetting to turn off lights and then failing to charge necessitates replacement. The safety risks are significant, as being stranded on the road is quite dangerous. It's advisable to check the battery's condition during regular maintenance to prevent such issues.
