We need a better battery performance,but are carbon additives the answer?

摘要

Thank you Brian,I am happy to help where I can.I have reviewed your information and results.To get things started we first need to understand the problem,and then break it down into several elements.Looking at the data you have sent there are two related issues:1.Low CCA test results.2.Reduced SAE J240 cycle life results.A good performance in both of these tests requires a low internal resistance and a high degree of AM utilisation.A CCA test is essentially the number of amps that a new,fully charged 12-volt battery can deliver at-i8°C(o°F)for3o seconds,while maintaining a voltage of at least 7.2 volts.The higherthe CCA rating,the betterthe starting power of a battery.The SAE J240,put simply,is a series of shallow,high-rate discharge tests at elevated temperature.The battery undergoes a four-minute discharge at 25 amps and is recharged for 10 minutes at 14.8V daily,and the number of cycles is counted before the battery is unable to meet the threshold voltage during the discharge phase of the test.
