Reasons Car Battery Keeps Drains

When your car battery fails once, you might be tempted to dismiss it as an isolated incident. There are countless possible causes for car batteries to expire, and there is always a chance that whatever went wrong won’t happen again. However, it’s a pretty safe bet that there’s an underlying issue that has to be addressed before you end up stuck somewhere if your car battery continues dying repeatedly.

Reason why Car Batteries Drains?

The list of problems that can kill a car battery is incredibly vast and seems to go on forever, but almost every battery killer can be grouped into one of three categories: battery issues, electrical system issues, or simple user mistake. There are some of them that can be handled at home, while others will undoubtedly need a trip to your mechanic, but you won’t know for sure until you get your hands dirty and start working.

It’s crucial to remember that when most people talk about a battery dying frequently, they usually mean when a car won’t start after being parked for any period of time. It’s more likely that you have a problem with the charging mechanism if your battery seems to die while you’re moving down the road (we’ll cover that scenario as well).

What Reawakens a Dying Car Battery?

Loose or corroded battery connections, chronic electrical drains, charging issues, continuously consuming more power than the alternator can supply, and even extreme weather are some of the most typical causes of recurrent automobile battery failures. Some of these issues are sufficient to destroy a battery on their own, others, though, are typically paired with a battery that is already poor or nearing its end.

1. The dome lights or headlights on.
♦ A battery will discharge overnight if headlights or even a very weak dome light are used.
♦ When it is dark outside, be sure to check for any internal lights.
♦ While certain headlights are intended to stay on for a while, a broken system can keep them on all the time.

2. Battery that is weak or in bad shape.
♦ A weak or improperly maintained battery may not be able to keep a charge very effectively.
♦  A very weak battery may die from even little drains, such as the memory feature in your car radio.

3. Battery connections that are corroded or loose.
♦ When you’re driving, corroded battery connections can prohibit the charging mechanism from topping off your battery.
♦ Another issue that can arise is loose battery connections.
4. Other electrical system parasitic drains.
♦ Although parasitic drains can be challenging to locate, they have the power to completely destroy batteries.
♦ Glove box and trunk lights that turn on or stay on erratically are common drains.

5. Extremely cool or hot conditions.
♦ A battery that is new or in good condition won’t die in hot or cold temperatures, but one that is weak or old may malfunction under such settings.
♦ Extreme temperatures can sometimes make other underlying problems worse.
6. Faulty charging systems.
♦ When you’re driving and a battery looks to expire, the charging system can be at fault.
♦ An alternator can malfunction due to worn tensioners and loose or strained belts.
