3 volts indicates a weakened battery. Check your battery before long trips to avoid unexpected failures.
Here''s the weird thing: The car does this about once a year. Typically I recharge the battery and it''s good to go. But this time the 12.3 volt drain isn''t going away. AND it seems to be accompanied by what appears to be a battery overcharge condition, where it boils the battery and flows acid all down the entire drivers side under the hood...

Free QuoteBattery Drain Monterey 12.5 Hi everyone, has anyone noticed a battery drain after updating to the last update Monterey 12.5? I did an update yesterday on my MacBook 14 Pro and since then I''ve noticed a battery draining which did not exist before. Checked all the applications and battery''s performance and didn''t find any issues.
Free QuoteI took out the voltmeter and checked the battery cold, it read 12.30 volts. I read that a new battery should be somewhere between 12.6 and 12.8 volts, so according to articles we have about 60% of the battery left. That does not seem like a great number. Is this battery ready for replacement?

Free QuoteSulfation is a big reason for battery failure. It happens when lead-acid battery plates get coated with lead sulfate. This makes the battery lose its charge and eventually fail. Batteries that sit in a low charge state often get sulfated. Internal short circuits also cause battery failure. If a battery shows 0 volts, it''s had a major short
Free QuoteThe battery temperature might not be the same as ambient temperature, it can''t hurt to see if an automatic charger increases the rested voltage. The addition of an amp, and using it with the engine off will heavily influence the remaining battery life, as it is also likely charging slower when driving due to increased load.

Free QuoteA normal car only has a parasitic draw of about 50 milliamps. That''s not enough to pull the voltage down on a healthy, fully charged battery to 12.4 volts. Even a worn battery will show higher than 12.6 volts right after being fully charged. They call this the surface charge.
Free QuoteA normal voltage range for a car battery is typically between 12.4 to 12.7 volts when the engine is off. A fully charged car battery should measure around 12.6 volts.
Free QuoteUnderstanding Car Battery Voltage Readings Fully Charged Battery Voltage. A healthy, fully charged car battery should register a voltage of 12.6 volts or higher when the vehicle is off. This indicates that the battery is in good condition and capable of supplying the necessary power for starting the vehicle and running its electrical systems.

Free QuoteNot a definitive test but the 12v battery shouldn''t drop below ~10v while cranking. Load testing the 12v is a far more accurate test for indicating battery health.
Free QuoteIt''s not the battery. 12.3 is a normal, key off, static battery reading. Measure any car battery, and you''ll get roughly 11.5-12.7 volts. They can''t produce more voltage than that unless something has gone wrong internally. If a battery causes the charge reading to drop significantly, it is because it has a bad cell internally.

12.6 volts or more: A voltage reading of over 12.6 volts indicates that your battery is fully charged and in good condition, so there is nothing to worry about. 12.5 volts: A reading of 12.5 volts shows that your battery is healthy and 90% charged.
A car battery with a voltage of 12.2 volts indicates that it is partially discharged. While it may still be able to start your vehicle, it is recommended to recharge the battery as soon as possible to prevent further damage. What voltage is too low for car battery?
It is less dependable than a fully charged battery because the success of a start at 12.3 volts depends on several variables, including battery state and temperature. When the voltage ranges from 12.25 to 12.3, or when the Specific Gravity is about 1.200, the battery is about 50% drained.
Initially, it may seem okay, but there is a problem if the voltage drops rapidly. If the voltage falls below 12 volts, it is usually a sign of a damaged battery, and if it drops to 10.5 volts or lower, you need a new battery.
Federal Hwy #216, Delray Beach, FL 33483, USA. A car battery at 12.3 volts is not ideal. It indicates a partially charged state and may lead to startup issues, especially in colder conditions.
