4 Pack Samsung High Drain 25R 20A 2500mAh 3.6V Rechargeable Flat Top Batteries (Green)

True advertised capacity for these cells unlike some fake chinese cells.Tested capacity at 2600 to 2800 mAh with internal resistance of 20 to 36.Cells I received have a production date is Mon Oct 02 2017.These also come in a 4 cell holder plastic box to protect them.

I bought these to replace my 2 year old LG HE2 batteries (which have the same 20A discharge and 2500mah capacity ratings as these "Samsung" batteries). After two years of use they just didn't hold a charge as long as they used to. These batteries don't hold a charge nearly as long as my used up old LG HE2's. I highly suspect that these are counterfeit and are not genuine Samsung.

Very long lasting 18650 batteries. I’ve tried many other brands and these are the best so far. I’d say these are right are par with what the Tesla Model S uses in their car. Very happy with purchase. Would buy again.

With batteries there are only two possibilities. They either meet your expectations or they don't. These are good flat top 18650s.

These are not bad but I wish they lasted longer.

Nice batteries

Don’t hold charge as long as the cheap ones I have

Great 18650s for my vase mod.
