I have asked for another update on listing the cooling unit body separately, hope to hear something soon.
My OG Roffu is now just over 2 years old and the puff counter has just reached 10,000.
I did find out the puff counter does not advance by simply turning it on as my counter was on 09995, and I wanted a 10,000 pic and tried to advance the counter for the pic...3 sessions later the counter was still on 09995...it only went up after I puffed on it.
I ran the test using 2x 6-minute sessions at 190c/375f as before but left my silicone armor sleeve. It must have skewed the test as I got 1 extra (11 in total) 6-minute session with the old battery compared to 2 years ago!
I have never looked after this battery, always runs to dead flat and is charged straight after use, so I was surprised to see the internal resistance is still only 45m/ohm (this is less than when brand new
) with a capacity of 2563mAh.
I just rerun the test without the silicone sleeve and let the unit cool between every second session and I still managed 8x 6-minute sessions from the old battery. I also let the battery cool before charging and my Nitecore SC4 charger says the internal resistance is only 51m/ohm with a capacity of 2430mAh...this test,
OG test from 2 years ago,
So overall I am more than happy with how well this 18650 battery is holding up and the Roffu is still chugging away nicely too.
