Reduced Weight = Increased Horsepower!

Physically speaking, shedding pounds is like adding more horsepower to your vehicle. You don’t have to have a McLaren P1 or a Porsche Boxster to have a lithium battery in your vehicle! EarthX lithium batteries provide incredible cranking power and last much longer than traditional lead acid batteries. EarthX batteries are typically 80% lighter than lead acid batteries.

For example, if you have a 50-pound lead acid battery, you can replace it with a 10-pound EarthX battery, now that is some weight savings! And to reduce this amount of weight, there is no less expensive way to drop 40 pounds for the price of switching from a lead acid to an EarthX lithium battery!

EarthX lithium batteries are ideal for performance race cars or automobiles where weight and horsepower are crucial factors. To keep costs as low as possible, these batteries feature less amp hours than traditional lead acid batteries. If you drive every day, your charging system will keep the battery charged without issue but 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.

How to choose the right lightweight 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.

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.
