All current vehicles operate at 12V. Therefore, batteries for these vehicles are all 12 volts.
However, for those who own a classic car, the voltage these vehicles operate with is 6 volts. That is why at FQS Battery, we have our own selection of batteries for classic vehicles.


- The FQS75B.0 battery has the capacity to provide 1A continuous current for 75 hours.
- The FQS75B.0 battery has the capacity to provide 7.5A continuous current for 10 hours.
When we start our vehicle, the engine must receive a brief but high-intensity energy discharge. That is the starting power. Not all engines need the same power to start. Some vehicles are sufficient with 45 amps, while others need 90 amps or more.
Hence the importance of this value. We must select the appropriate one for our vehicle to start, but without overdoing it, as an excess of starting amps can cause problems. And without falling short, because then the vehicle will not start.


Our batteries always indicate the range they belong to, which refers to the technology they employ.
Related Important Information: Can an EFB battery be replaced with an AGM battery?
And if it doesn’t have one, your vehicle can use a conventional battery or an EFB battery. But always provided that the values are in accordance with the vehicle’s needs.
Passenger car batteries gradually lose their energy charge due to the vehicle’s operation and the electronics the car uses, such as screens, radio, etc., which we can enjoy inside the car. This is where the alternator comes into play, recharging the battery while the vehicle is running. So, as long as the battery and alternator are in good condition, the car battery will have enough energy.
Our batteries indicate the minutes the battery can supply power at 25 amps when the alternator, for whatever reason, is not recharging the battery. That is, time to get to a workshop to solve the problem so that the car doesn’t leave us stranded due to lack of power.
Obviously, the minutes provided by this data will also depend on the number of screens in use and other devices that are currently operating in the vehicle.
