  • Check engine light: Another common sign is the presence of your check engine light. If the voltage provided by your battery is too low, that light will illuminate as a goal-line defense before it finally dies.
  • Battery corrosion: This one is tricky to tell since it requires a look under the hood. If you notice any crusty-looking substances on the + and – ends of the battery, then your battery is likely leaking and needs to be replaced.

What Happens When I Disconnect My Battery

Disconnecting your car battery for regular servicing, such as swapping the battery for a new one or placing a car in long-term storage, should not cause permanent damage to your ECU, as long as you follow the correct procedure.

Depending on the ECUs design, it may or may not remember some of your settings, such as your preset radio stations, for up to 72 hours. If your ECU controls the anti-theft system, disconnecting the battery may lock you out of your car.

Like desktop computers and most other electronics, disconnecting the battery cable for a short period will not fully reset your ECU due to the residual power remaining in the circuits. If you want to perform a full reset, wait at least 15 minutes before reconnecting the battery to ensure all residual power has been drained.

A full reset reverts your ECU to its factory settings and likely causes it to forget its learned ideal shift points and air-fuel mixing ratios. When driving shortly after a reset, you may experience rougher acceleration and shifting than usual.

Under normal circumstances, you dont need to do anything else other than keep driving the car after resetting the computer. The ECU will eventually relearn its ideal settings and reprogram itself with use.

    Do Evs Have Different Batteries Than Gas

    As EVs – hybrids, plug-in hybrids, and all-electric vehicles – become more mainstream, many drivers are curious about the mechanical differences from a car with an internal combustion engine . And with good reason, there are some crucial differences beyond how each vehicle is powered.

    When you dig deep under the hood, youll see that EVs and ICE vehicles rely on different types of car batteries. As previously mentioned, ICE models use lead-acid batteries, while EVs rely on lithium-ion batteries, commonly used in electronics like smartphones and laptops.

    Lithium-ion batteries are more energy-dense than lead-acid, prolonging the overall lifespan and ensuring greater energy efficiency. They also have a higher performance in higher temperatures than lead-acid batteries.

    An added benefit of EVs and lithium-ion batteries is that they have a much more extended warranty period than most batteries. Federal regulations require automakers to have a minimum warranty period of 8-years or 100,000 miles . On the other hand, a lead-acid battery is only covered for five years at most.
