2010年4月28日 · An example Ragone plot for three different AA cells is shown in the plot below: The data on this Ragone plot was collected on a Maccor cell tester using constant power discharge and measuring the discharge energy to a 0.8V cut-off.

2010年4月28日 · Given that I need to finish up the AA Ragone plot and still have a lot to do on the 18650 Ragone plot, it may be awhile before I can get to the cycle life study. What were you thinking for charge/discharge parameters? I propose the following: Charge: C/2 to 4.2V (unless otherwise specified by the manufacturer); CV at 4.2V to C/50 current cut-off

2010年4月28日 · Duracell Ultra Lithium test results added to the Ragone plot in the the original post. All I can say is WOW! Although it appears that the total energy is a bit lower than the Energizer lithiums, the Duracell lithiums are the clear winner when it comes to high power draw. Very impressive results for a primary battery.

2007年11月21日 · Ragone plots are usually the first thing I turn to when evaluating new batteries for a device. Once I have down-selected to a few best bet choices, then device specific testing is usually necessary. That being said, it is very rare that cell performance in a device varies substantially from the Ragone plot.

2012年4月16日 · Yeah, OK. It looks like they may have close to a Watt advantage, at high rate. I was just wondering if their was a difference in age, and that might have had anything to do with it. Looking forward to the Elite 1700 results. They are obvoiusly not capacity Kings, by …

2010年4月28日 · Ragone plots are a great way to compare the performance of several batteries under various constant power loads on the same plot. Most of the cells will be discharged up to 8W. I have taken a few cells above 8W, notably Eneloops, Elite 1700, PowerGenix and Imedion 2400. However, limitations of my test equipment make it difficult to go above 8W ...

2010年5月22日 · The PowerGenix cells really do appear to shine in at the upper end of power spectrum. These may turn out to be the cells of choice for many really high lumen output torch modifications. Yes, of course you are correct. I want to mention that I was thinking along the lines of how I will be...

2010年4月24日 · By the way, I have actually tested a recent version of the UR186450W and the results are plotted on the Ragone plot in this thread. This cell has phenomenal power/current delivery capability. It is absolutely perfect for high power hotwire mods, if you can get your hands on them. Cheers, BG

2009年1月1日 · This was covered in the thread 'AA Ragone Plot', but that was before they were upgraded. EA91 from '4x' to '6x' & L91 from '8x' to '9x'. If you find '7x' Energizer Ultimate Lithium in stores, check the expiration date, because they …
