Samsung 25r's needing to be 'woken up'?

[raige93]

I read somewhere, I think on juice Junkies, not that it matters, that Samsung 20r and 25r's need to be 'woken up' IE charging as normal when you get them. Discharging as you would normally, then repeated about 5 times, but all at .5 ohms or higher. The author of the post stated that doing so (I think this is what he said here): " Maximizes their potential, they have a lower internal resistance by doing this, they capacity (mAh) stays higher, longer, and it was overall 'healthy' for the battery. Does anybody have any input on this?

In my experience with RC batteries, this only needs to be done if the batts are pretty drained when you receive them. This cycling "opens" them up. But I havent heard of this with any Li-ion type batts, only with the older nicad/nimh batts. I say the 25r's are cheap enough (and available enough) to just use them as is

I've been using 25r's for about a month and have had no issues. Not sure about longevity yet but they have been lasting all day+ for me. Like silver said, for the price I just used them as is and have yet to notice anything wrong.

What ohm are you at? Have you had Sony VTC4/5 to compare to them?

lithium batteries need a few charge-recharge cycles to reach their full mah potential. im betting thats what youve read about in essence.

I find that they perform better than VTC5's. I own both and hardly ever use my VTC5's. Makes sense as I saw a chart where the 25R outperformed the VTC5 for the first 1000mAh at 35 amps.

Samsung 25R and LG HE2 are rated 20 amps continuous vs the VTC's at 30 amps. When they are tested at over 20 amps I'm pretty sure they are cooled. They go up to around 200 deg F at 20a. VTC3, 4 and 5 get just as hot at 30a but they run cooler at 20a.

35 amps is a 20a batteries burst rating. Kind of like running a VTCx at 60a. Not the safest thing to be doing
