Help battery over charge

luigi90210

well first things first, measure the voltage while the car is running at the battery terminals, you might not be overcharging but the car can think you are if the voltage sensor is bad(i think thats what the gauge and ECU uses)

you should read exactly 14.7v if its a little higher or lower, dont worry about it(meaning dont worry about overcharging your battery take the car in to get the sensor replaced if under warranty), as long as its under 15v and above 13.6v, its fine

if you are seeing an overcharged battery, first off take it to the dealer if you have warranty still, either your voltage regulator or your alternator has gone bad and request for your battery to be tested as well, overcharging a battery can lead to bad news(explosions, dead batteries, ect.) later down the road depending on how bad the overcharge is

if dealer wont test the battery, take it somewhere else and have the battery tested, if it isnt passing take the car back to the dealer and demand for a new battery since it was being overcharged
