Charging a car battery while still attached to the vehicle is risky, as there is a significant danger associated with overvoltage or short circuits. However, you can still charge a car battery when connected by exercising preventive measures to lessen injury or car damage. This article will let you know the consequences of charging the battery, tips on the best time to disconnect your battery before charging, proper ways to charge the battery, and many more.<\/p>\n
However, most car<\/a> manufacturers will recommend that you turn the engine off before charging a battery, allowing the alternator to supply enough power to charge and run your car.<\/p>\n It is always best to check the manual for your car to see what is recommended. Some of the best battery chargers on the market can charge<\/a> your car’s battery while it is still hooked. And mostly, quality batteries take at least four hours to charge.<\/p>\n If you have a modern microprocessor-controlled charger, it would be the best way to charge your car battery. This device will monitor the battery and charge it at the proper voltage<\/a>.<\/p>\n Use a good quality charger for your vehicle, whether it is an older model or not. But, if your charger is old, it can be dangerous to leave it connected for too long. It cannot tell the difference between full and overcharged batteries, so they keep charging until you unplug them. In case of a reverse polarity connection, your charger could still damage diodes in your rectifier, so be very careful.<\/p>\n Modern chargers will charge your battery at around 10% of the capacity. It can tell when the cable is plugged in backward and stop charging<\/a> your battery right away. For example, if you have 100 amp-hour batteries, the charging current should not exceed 10 amps to avoid damaging them.<\/p>\n It is possible to start the car with the battery<\/a> charger attached, but it is not advisable. Chargers are not designed to provide a high current, say 100 amps max. When you try to start your car, the battery may be supplying only ten amps of power. The charger will blow out and even get damaged if it tries to draw in more than that amount.<\/p>\n If you leave the charger on while running, it will keep trying to charge. It may also supply power for other components in your vehicle if they are not drawing enough on their own, like lights or dashboards.<\/p>\n Some of the chemical reactions within your car battery<\/a> will cause it to become damaged. Also, if you do not take the battery out, there is a chance of leakage and the battery shorting out.<\/p>\nWhen is the best time to disconnect the battery before charging?<\/h2>\n
