samsung 25r vs efest purp 35a 2800mah

[genelbc]

Given what everyone say that 25r's are top of the line and efest rewraps and lies about their bats. My 25r's suck in comparison to the purple efest 35a 2800mah. The efest last roughly twice as long no matter what watts im running. I also find it quite interestimg that the efest were half the price of the 25r's.

Anyone else care to weigh in on this?

You found Efests for $3?

In my testing the 25R lasted about 15% longer, and ran about 7°C cooler, than that Efest. The Efest tested as a decent 20A battery but certainly not 35A. Have you checked to make sure your 25R's are genuine? Were the 25R's and the Efests purchased at the same time?

I wish i found for 3$. The efest were 7 and the 25 r were 14. Purchased about 2 weeks apart. The 25r are the newer of the 2. From everything i can tell they are genuine. They are the blue ones if that makes a difference. As for the amps i cant test that im just speaking from what i have experienced over the last week of switching between the 2.

I've seen the 25R's going for about $6 so that's where I got my $3 price for the Efests.
Here are some close-ups of a genuine blue 25R you could check yours against, if you wanted to...



If you're getting much better life out of the Efests than the 25R's then I say stick with the Efests. Any testing that has been done doesn't matter if you feel the Efest is better. I recommend staying below 65W or above about 0.2 ohms when using the Efest though as it's a 20A battery.

$14? Where are you getting batteries? They're $5.50 from illumn, $6.79 from RTD...

I have noticed a few different shades of Purple on efest, like a softer vs. a darker Purple. Mean anything?
