So I ran across this battery from EBL 18J Lithium Ion rechargeable 18650 3000mAh / 11,100mWh with 3.7V constant voltage output.
Seriously, check out this graphic found on their official website 7 days ago (but since replaced)
Now I KNOW this is all too good to be true.... UNLESS .... This is obviously made with some sort of reverse engineered technology.... or they're only testing with like a 0.01A parasitic drain....... Cannot find anything on how they came up with their specs for this battery btw...
Sometime in the last 5 days, EBL replaced all the website graphics from the dark background to a light blue background.... though Amazon still shows the original graphics.
Gone is the spiffy straight line graph with an almost perfect drop at 0.1% capacity... but still claiming 3.7V constant voltage discharge in the new graphic.
Would be a heck of a deal if they lived up to the hype at about $9 each..... so I decided to check them out for myself.
Interesting note: batteries say... well, see for yourself:
"Can only be charged by compatible EBL USB cable"
"pre-charged battery"... one was, one was not. Using a 30W USB fast phone charger that I use with my Xtar VC4SL charger, and the included Y split USB micro charging cable, one of them took about 4 minutes for the LED to change to blue indicating fully charged, the other one took about an hour and ten minutes +/- 2 minutes
Also, this is supposed to charge by USB-C according to the NEW graphic.... though the old graphic clearly showed batteries with Micro USB ports like I received.
Sadly.... Even at just 0.2A discharge, it's failing miserably.
And how about this graph.... WAIT A MINUTE.... that's not a laser straight line at 3.7V......
EDIT: I only discharged to 3.0V, but only showed 1964mAh discharge capacity, no where near the claimed 3000mAh
