CCA value is irrelevant for a Prius. It may be painted as fake news, but just learn it (chemistry) if in doubt. Unfortunately other measurable units are not advertised or easy to know. The long term and low temperature (in my case) endurance is so much more relevant. Yuasa model is the absolute best value/endurance time value in my experience with so many dead trunk batteries at winter times… Up north we know battery capacity drops tremendously when there are subzero temps. If used low they will empty their entire charge. Please note a frozen battery is not wasted, it likely froze due to lack of charge (pH is to high). But any battery that has dropped to below even be able to start the Prius ECU should never be considered healthy nd only used as backup. Any artery or battery will be able to deliver 300A directly after charging. It’s not viability in my mind.
That’s a testament to quality indeed. Since the dimensions and pole dimensions and positions (!) are rare, I have tried em all. Any battery claiming high CCA is by my definition easily emptied.
Agree, higher CCA seems to come at the expense of lower amp hours, it's a trade-off, on or the other.
Indeed. It’s two different focus areas design-wise. Either you deliver a lot now and store less, or you deliver less and hence store more. It’s not just fluff, the design of plates and electrolyte flow is very different. I have not tried lithium as an aux at all, partly due to lack of trust in cold climate sustainability. Might be idiocy, but price is also highly relevant… My experience: avoid Bosch, Excide and Yellow Top, if you live with subzero nights.
