• If you see any of these signs, you should replace your car battery immediately. While it may have a little bit of life left in it, its imminent demise is near. Leaking, cracked batteries, or producing a rotten egg smell should be replaced immediately, as they are hazardous. A car battery with bulging sides is also an extremely hazardous situation, and the battery should be replaced immediately. - Source: Internet
• Because our car needs direct current, it is sent through a couple of diodes; to convert it into the direct current. Because this stator has three separate windings and each one needs two diodes. In which each is required in total. This six-pack of diodes is called the rectifier; the other end is the B post, so this D/C converted current is going to the battery. Now we test each component to check the voltage regulator in the engine at around 2,000 RPM and note down the reading. - Source: Internet
• When to change your car battery depends on the battery’s quality, how well you take care of your battery, and the weather. Storing it at the proper temperature, avoiding leaving your lights on overnight, discharging it to low levels, and other factors all determine how often you need to replace a car battery. The bottom line is that if you are experiencing any of the symptoms of a battery that is having problems, it is best to test it and change it if it is needed. Battery problems do not fix themselves, and they only worsen over time, until eventually, you end up stranded, and your car will not start. - Source: Internet
