You’ll likely be charging it inside your garage, where the temperature will be above freezing. That being said, it is highly unlikely you will be charging your lithium starter battery outside in the winter. But, while lithium can discharge in cold temperatures (-20☌ or -4☏), the lowest it can charge is at freezing point (0☌ or 32☏). Its capacity and life are affected in the same way as SLA – as the temperature goes down, capacity goes down, and cycle life is extended. There is a downside to lithium – it is limited by cold weather. ![]() This leaves it up to the battery manufacturers to decide how they want to test their batteries. As indicated above, there is no true standard for cold cranking amp or continuous cranking amp testing for lithium batteries. Is it also important to note that when checking out “CCA” ratings on batteries, that you clarify if they mean “continuous cranking amps” or “cold cranking amps”, and to even check how they are being tested. This means that continuous cranking amps, especially when conducted at cold temperatures, are still a good indication of the cold cranking amps the battery is capable of providing. As you may remember, the JIS standard checks for voltage after 5 seconds and is only conducted at -10☌, and is specifically intended for SLA batteries, not lithium. In our Hyper Sport Pro line, this testing is conducted after the battery has been kept at -20☌ for 20 hours, and then tested with continuous current for 15 seconds. What is oftentimes tested in lithium batteries is continuous cranking amps. You can learn more about constant power in lithium batteries in The Complete Guide to Lithium vs Lead Acid Batteries blog. This means the lithium battery can deliver the same amount of power at 15% discharge as it can at 85% discharge, which shows how the voltage aspect of testing isn’t relevant to lithium batteries since the voltage isn’t dictated by the SOC. ![]() CONTINUOUS POWER FROM LITHIUMĭon’t be worried about the lack of standards for lithium, because there are other factors that we can use to evaluate the two chemistries.įor example, lithium delivers a continuous amount of voltage across its cycle, unlike SLA batteries whose voltage is dependent on its state of charge (SOC). You might be thinking, “does this mean my lithium battery won’t work in cold weather?!” The simple answer is, “No.” The long answer is that automotive testing of CCAs do not apply to lithium and there is currently no standard related to lithium. Going one step further as we talk about lithium batteries within power sport applications, we can see that the automotive standards for CCA testing cannot be conducted on a lithium battery. In the What is CCA on a motorcycle battery, part 2 of our trilogy on CCA blog, we covered the reasons why CCAs aren’t exactly applicable to power sport applications. When selecting your lithium starter battery, you will notice there is oftentimes not a Cold Cranking Amps (CCA) rating listed for the battery like you would expect with an SLA battery. ![]() Although it is a relatively new lithium chemistry, it is still a common choice for lithium starter batteries. Lithium Iron Phosphate, often referred to as LiFePO4, – the chemistry for Power Sonic’s Lithium Power Sport batteries – has only been around since 1996. ![]()
