The voltage of the battery in a Subaru WRX is 12 volts. Most Subaru WRX models come from the factory with a flooded lead-acid battery, but owners have the option to replace it with a sealed, AGM OPTIMA battery. It is important to maintain proper voltage in the battery to maximize its performance and lifespan.

Is 11.9 volts enough to start a car?
Before starting, the minimum voltage needed to create a car should measure 11.9V, and after starting, You have to check or replace your starting battery if the voltage is between 12.8 to 13.2V.
Is 14.9 volts too high for an alternator?
13.5-14.7 is normal range. Below 13.5 NO CHARGING is occurring. Never should it be lower than 13.2 unless your in a vehicle that stops its engine at red lights or you are idling with a very high load like air conditioning on full, headlights, ect.
Is 14.2 battery voltage good?
The voltage profile will depend on the specific battery, but for your typical iron phosphate batteries, the range is 14.4 ± 0.2V. In other words, you should monitor between 14.2V and 14.6V while the battery is actively charging. Anything less might just be a trickle charge, if it charges at all.
What is the voltage of a Subaru battery?
Car batteries typically carry 12 to 13 volts unless you have a high-performance battery. Anything higher than 13 volts may indicate a faulty battery.
Is 14.8 volts too high?
14.8V is quite high for a sealed cell. It will probably reduce the life of the battery. Boost max is typically around 14.2 and absorption around 14. You should check your battery specification.
Is 11.9 a dead battery?
A fully charged battery should register at 12.7 volts or more. If the voltage falls below this number, the battery should be recharged. A battery is only charged by one quarter at just 12 volts. Once it drops to 11.9 volts, your battery is considered dead.
What is battery voltage supposed to be?
12.6 volts
When discussing car battery voltage, we’re generally talking about a 12-volt battery. When we take a closer look, we see car battery voltage can range anywhere from 12.6 to 14.4. With the engine off, the fully charged car battery voltage will measure 12.6 volts. This is known as “resting voltage.”
At what voltage is a car battery dead?
11.80 volts
A car battery’s voltage may vary but only in a narrow range, from a fully charged 12.88 volts to a totally dead 11.80 volts. The difference between a fully charged car battery and a dead one is only 1.04 volts.
At what voltage is a battery low?
If the measured reading is less than 12.2 volts, the battery’s resting voltage is weak, which means it most likely needs to be charged or replaced. Once the resting voltage has been determined, it is time to get a reading on the crank cycle.
What is a bad voltage for a car battery?
At 12.4 volts the battery is considered 75% charged and can still ignite your engine. When the battery voltage lowers to 12.2 volts without the engine running, it is considered a bad battery that may start your engine but is no longer capable of holding a charge.
