The 18650 batteries are equipped at both ends with a nickel-plated S.S. protector ensuring high impact resistance, good electrical conductivity and oxidation resistance. To prevent against abrasion the cells are coated with a durable metallic film, as well as the circuit board being coated with tough plastic. The innovative anode was designed to resist high temperatures, while the microporous barrier protects the delicate internal components.

Early Impressions
I have not had the product long enough to do a thorough review. The product came in a timely fashon. It was packaged well in a blister package single unit. The battery looks robust, and appears to be well made. There are allot of options out there, and lets face it, looks sell. I bought this battery based on performance and product history. It seemed to take a charge well without excessive heat generated, No noticeable change in product dimensions. Thats as far as I can go with my review. It looks like it will perform well, but time will tell.As a general rule of thumb, I buy name brand products when my safety depends on it. Kind of like buying ammo, Go with the best track record. I generally read reviews.

Good Cell, Great Value on Sale
If you're like me, new to these new high tech power flashlights and cells, and remember the days of NiCad short shelf life, leakage, and poor cycle life, then you're skeptical about paying too much for cells you don't know will last. Fortunately there are enthusiasts who test and use these cells and lights extensively and share their results. Even then, even when we're convinced and more comfortable with the capability and endurance of ICR, IMR, and primary Lithium cells, we're still skeptical about brands. Certainly what it takes to design, and, more importantly to make these cells requires expertise, equipment, processes, and controls that few manufacturers have mastered around the world. That being the case, it is less likely that major name branded cells will suffer from poor lot to lot variance in capacity, current handling, shelf life, service life, and cycle life. We might tread cautiously with brands whose name we don't recognize, but we can depend that cells branded with the flashlight maker's name will both fit and function in their lights. So that's the first step, and that's what I did in buying a second Nitecore 18650 2600mAH cell to match that included in Nitecore's combo HC30 Kit. Fit and finish of the cell is fine. Charged with no issues in the Combo Kit's i2 charger. Works, delivering the power of the HC30 light. Amazing power potential for all manner of technology gear. I chose the 2600mAH again from the fear of the bleeding edge... I'd rather have two 2600mAH at a sale price than a 3600mAH at a higher price despite the potential of run time difference. Now if I used a light on high for hours a day, I'd likely have chosen differently. Still, in this point in time it is possible that even Nitecore's and more likely other branded cells of high capacity might actually not fit. Especially when starting out, buying the same one that was originally included is only being wise. And watching buyer feedback about what fit and what didn't in what, or what fit but didn't work in this or that is only wise. I intend to try an Xtar's cell next unless name branded cells go on sale for less.
ProsSame cell bundled with Nitecore Combo Deals - gives confidence in fit and function Light manufacturer's name branded cell - gives confidence in capacity, current carrying, shelf life, service life, and cycle life Charged up fine in combo i2 charger; works perfectly fine in HC30 Headlamp Adequate capacity for a reasonable run time at mid range brightness and infrequent use
ConsA premium price compared to cells not branded with light manufacturers' names

Adequate Capacity for Most Needs
Giving a review for this cell shortly after purchase doesn't give the whole picture. Nonetheless, this was bought for a Nitecore HC30 Headlamp. It is the same cell sold with their combo, so I was not concerned it wouldn't fit. My use for the HC30 ranges from that of weekend-outing headlamp, for which this capacity gives more than adequate runtime at the lower lumen levels of campsite and late night walks, to that of just-in-case outdoor use, where either the Turbo Mode or the Strobe would be used quite briefly. In these roles the 2600mAH capacity is just fine, and the cell fits perfectly into the HC30 without concerns that might be realized by a much higher capacity cell from Nitecore or another brand.

I have 2 Lights that take #18650 batteries that are rechargable. I had been looking for less expensive alternatives than the ones that came with the lights. These seem to be the ticket in price and performance, time will tell if I made the right choise.
ProsWell packaged ( came with plastic cases ).
ConsTime will tell if they hold up to use

Works fine
I have six Nitecore 2300 mah 18650 batteries, but these 2600 mah 18650s came along with an i2 charger when I bought the EC4S. The 2600s obviously take a little longer to charge, but they also last a little longer as well. The length listed on the specs is 69.6mm for the 2600 and 68.8mm for the 2300. Without a caliper, they appear the same length when stood up side by side. I use the 2600s in the EC4S and they work fine. I'm happy with the batteries.

Beside wear and tear, it gets the job done.
I usually would have gone with a bigger capacity (mAh) but I got it with a combo deal, but I don't mind it. I have currently charged this sucker so many time through out 2 plus years and there is no sign of rapid in discharged or delay charging. Everyday after a work I go home and I throw my battery (ies) onto the charger every night so my batteries are at 100% or so. So I can safely say my batteries has probably surpassed over 500 charges.
