Samsung 26F 18650 2600mAh 3.7V Lithium Ion (Li-Ion) Unprotected Flat Top Battery
September 26, 2017
The order went smooth ordered over the holiday so did not go out right away but I do not mind everyone needs to take off on a holiday. They came packed well and all voltages were right on just 4 out of 56 were .003 off which is no problem
Pros
- authentic, packed well, came fast even though I ordered on holiday
Cons
- None will buy some more

too long in length
August 30, 2017
I bought these to replace my currently in use 18650 2600 mah 3.7v batteries. The part # is identical to my old one but yet it is not the correct length. What's the point of "matching" up the part numbers if they are different sizes. Waste of time & money!

Great quality batteries

Bought them for a powerwall. I tested these batteries and they have exactly the stated capacity as described. Hope they can last a long time and keep their charge.
