Please make sure the cables are tight enough and can’t be pulled off of the posts easily by hand. - Source: Internet
• Another thing to remember with newer cars is that if an electrical source causes the power to be drained from the battery , this is called “parasitic loss.” This can happen when your engine and all the vehicle’s lights are turned off too. Why? Because there are certain electronic systems and features in your car which are still consuming power after your car is turned off, such as the clock and computer. These things won’t normally drain too much power from your battery but if you suspect they are, then either remove the battery completely or simply disconnect it. - Source: Internet - Source: Internet
• You should also check the Reserve Capacity rating (RC), which is the time (in minutes) a battery will deliver 25A and maintain 10.5V. You are looking for a higher reserve capacity should the charging system fail. - Source: Internet
• Of course, a repeatedly low charge doesn’t mean your battery is dead. It could be good and several scenarios might lead it to lose its charge: such as lights being left on, undriven for long periods, dodgy alternator, or even parasitic draw through any number of electrical circuits in the car going awry. Even an errant radio or internal light connection can repeatedly flatten a good one. But a positive outcome of the tests outlined above should prove the battery itself can hold a charge. - Source: Internet
• You can check for voltage drop between the battery terminals and cables by first testing on the terminal and then on the wire crimps going out. Anything over around 0.1V less than what is coming out of the terminals suggests high resistance/bad connection. Clean the terminals/connections with sandpaper and tighten them up. - Source: Internet
