But if it's just one voltage reading during the middle of a constant current charging regime, it could be normal. It should also be noted that outside temperature affects the optimal charging voltage. So in a very hot climate, 13 volts could be normal, but then again in such climate, you can't expect the battery to have a long life.
If your car battery shows 13 volts, there might be an issue with the electrical system. The chemical reaction occurs in the battery system, transforming the chemical energy into electrical energy to deliver voltage to the starter. In addition, the battery stabilizes the voltage to keep your engine running consistently and constantly.
The voltage of the battery itself with the negative terminal disconnected was 13.7, higher than expected. The circuit with the engine off was lower but less than 0.1 volts lower, within rounding.
A standard 12-volt battery should have a voltage between 13.5 and 14.5 volts when the car is running. However, you should keep in mind that a battery that reads low isn’t necessarily dying. The best way to find out if your battery is dying is to read the voltage on your battery several times over an extended period.
Your battery supplies your car with power. Thus, a low battery voltage could affect your car’s performance. But, you’re probably wondering, what exactly is an adequate battery voltage? While a car is running, the battery voltage should be between 13.5 and 14.5 volts.
13V does seem low, I would expect 13.7 to 14.8V (and on my car it can go up to 15.3...). However, have the voltage checked with a quality or professional meter - I have seen people using those cheap "chinesium" 10 buck meters which can have an error of 1V or more...

Riding mower won''t start, multimeter shows the battery at 12
A multimeter measuring voltage does not "test" a battery. It needs a load on it to test it, which is what a battery tester does. If it starts with a jump it most likely just needs a new battery. You can take that battery to a repair shop and they can test it for free. Voltage present on a battery means very little, it''s the current (amps) that ...

Battery Voltage low when car is running. Should I be concerned?
I would suggest 13.5-14.2vdc is usually a better indicator of output. It really depends on the vehicle and how the charging system was designed. upper voltage range can be 14.8v - does depend on the car though and the type of charging regime - mine can and has gone up to 15.2 but that is normal for my car.
