The "VPH" series are the most popular Voltphreaks batteries. The main thing the battery needs to do is start the car. Once the engine is running, the alternator supplies the power. The chart below breaks up the various Voltphreaks models by the size of the recommended engine they can start.

These are general recommendations, what is best for you can depend on if you have a harder or easier to crank/start engine, if you use your car in a warm or cold climate, engine displacement, compression, etc.

If you have any questions about which battery is best for your particular application, feel free to contact us. Price list and product comparison chart can be found here.

* Note that some Porsche GT models may not properly charge the Voltphreaks battery, due to the alternator's voltage being too low. Click here for more information.
