A current drain higher than 50 mA can gradually drain the battery and eventually lead to a dead battery. Some common causes of excessive current drain include:
1. Parasitic Draw: This refers to the current drawn by various electronic components in the vehicle even when the vehicle is turned off. These components may include the car alarm, clock, keyless entry system, GPS, etc.
2. Faulty Wiring: Damaged or improperly connected wiring can cause a constant current drain on the battery.
3. Aftermarket Accessories: Installing aftermarket accessories that are not properly wired or draw excessive power can drain the battery.
4. Faulty Alternator: If the alternator is not functioning properly, it may not be able to recharge the battery sufficiently, leading to a discharge over time.
5. Battery Condition: An old or damaged battery may have a reduced capacity and may not be able to hold a charge for a long time.
It's important to note that some vehicles may have higher acceptable current drain levels. For precise information, refer to the vehicle's owner's manual or consult with a qualified auto electrician.
