You don’t have to have a McLaren P1 or a Porsche Boxster to have a lithium battery in your vehicle! EarthX lithium automotive batteries provide incredible cranking power and last much longer than traditional lead acid batteries. Our lightweight automotive batteries also do not freeze, boil, sulfate, or corrode. They’re even 80% lighter than lead acid batteries!
EarthX lithium automotive batteries are not inexpensive, yet they are ideal for performance automobiles where weight and power are crucial factors. To keep costs as low as possible, these batteries feature less amp hours than traditional batteries. If you drive every day, your charging system will keep the battery charged without issue. If you want to sit with your engine off and listen to your radio, keep in mind that you’ll have less energy to do this.
It’s easy to choose the right lightweight automotive battery for your vehicle. First, consider the amount of current that your alternator puts out. Once you know the max amperage output, find out how many cranking amps you need to turn the engine over. Match these factors up, and you’ll know which battery to choose.
- The ETX1600 is 8.9 pounds. Max charge current rating is 160-amps. Delivers 1600 Peak Cranking Amps (PCA).
- The ETX1200 is 6.9 pounds. Max charge current rating is 120-amps. Delivers 1200 Peak Cranking Amps (PCA).
- The ETX900 is 4.9 pounds. Max charge current rating is 80-amps. Delivers 840 Peak Cranking Amps (PCA).
- The ETX680/ETX680C or the ETX36 series is 3.9-4.1 pounds. Max charge current is 60-amps. Delivers 680 Peak Cranking Amps (PCA).
Note: If your alternator rating is less than or equal to the max charge current of the battery, it is the right battery for your race car. Example: your alternator puts out 120 amps max current, then the ETX1200 would be your battery choice as it is designed to handle that amount of current.
If your alternator puts out 160 amps max current, then the ETX1600 would be your battery choice as it is designed to handle that amount of current.
Now what if you have a 180 amps max current alternator? You could put 2 ETX1200 batteries in parallel. Or you may be able to use the ETX1600 if your race car uses at least 20 amps to operate as this would drop the current to 160 amps, then it would be acceptable.
