Choosing the right starter for your car is not difficult and in practice there is only one characteristic to consider, namely the power, which is expressed in amperes. For example, a starter may not be suitable for batteries in trucks and SUVs because they have a different amperage than a small motor vehicle. Most batteries in cars have a rating of 12 volts and so the starters are compatible with that rating, but as mentioned earlier, a 12 volt battery can have a different amperage. You can find this information in the technical specifications for your car's battery.
