If you’re driving a car with a bad alternator, it’s important to know how long your battery will last. If the alternator is not functioning correctly, your battery will be drained much quicker than if it was in good condition. In order to figure out how long your battery will last, there are some factors that need to be considered.<\/p>\n

You know that your car will eventually stop if the battery is constantly being drained. The time it takes to get there depends on how often you drive, but a dead alternator can lead to an early death for your vehicle and leave you stranded in no-mans land.<\/p>\n

Your ignition system relies heavily on both the battery and alternator so everything works smoothly while driving down the road. It has been seen where batteries are not recharged<\/a> as they should be because of poor quality or old age; this results in longer periods between charges which causes vehicles with weak batteries cannot continue running without stopping due to their charge draining away too quickly. This becomes even more problematic when considering cars whose engines rely solely on electrical power during times of low-speed operation such as in traffic, or at stoplights.<\/p>\n

There are many factors affecting how long a battery will last when the alternator isn’t charging<\/a> it. The type of engine, how modern the car<\/a> is, and even if you’re driving in daylight or at night can have an effect on your battery’s charge–and so does its age! If you need to use headlights during dark weather conditions then that’ll take a toll on your vehicle’s power supply too. Below is two vehicle types that may help you:<\/p>\n

Classic Diesel Cars<\/h2>\n

Older diesel cars are very interesting and a lot different from newer models. The engine is usually the main power source, but it also drives some smaller gadgets like the fuel pump or hydraulic pumps for things such as steering fluid – all without electricity! This makes them completely portable once started, which can be handy in an emergency situation where there might not be any other sources of energy nearby to use.<\/p>\n

The battery that comes with these older engines will last<\/a> you several hours on its own before needing recharging, so they’re perfect if you know your car won’t have access to electric sockets outside of emergencies; however, this does mean that when using one at home (or anywhere else) while plugged into mains power then yes-the batteries will charge up.<\/p>\n

Gas-Powered Cars<\/h2>\n

In a gas-powered car, the engine is controlled by electronic systems. Unlike diesel, it has spark plugs that will be a large drain on the battery. The next big draw of power might come from the Engine management system and airbag systems. With all this going on, your average battery could last<\/a> as little as 30 minutes or up to two hours if you\u2019re lucky! If you have to start the car without an alternator (i.e., in case there’s no electric current), don’t turn off once things get started because the battery is quickly drained.<\/p>\n

Bad Alternator vs Bad Battery<\/h2>\n

A bad alternator is when the alternator goes bad, and your battery will be drained<\/a> much faster than if it was in good condition. A bad battery may mean that your battery isn\u2019t holding a charge<\/a> or dying much quicker than it should. Below are some signs of a bad battery:<\/a><\/p>\n
