18350 Rechargeable Battery IMREN 3.7V 15A Discharge high Drain Li-ion Button Top Lithium Battery for Solar Garden Lights,Flashlight(4PCS)

I have several small 'tactical' flashlights that require 18350 batteries. Since I carry the flashlights in my bag, I do use them a lot, and it is nice to have quality batteries on hand as spares. These batteries have a button top, so be sure your device can handle that.I've tested these batteries, and found they do meet/exceed the stated ratings (these tested at 900mAh). I've used other IMREN branded items before, and they're always top quality.

It's tough to find legit lithium rechargable batteries around here. Lots of overstated capacities and rewrapped old cells. Thankfully that is not the case with these Imren 18350's.Everything checks out fine. Each cell measures over 90% of stated capacity which is much better than many others. That's within the margin of error of my charger so I will say these are legit. Internal resistance on average measures around 70 milliohms which is about normal for an 18350 in my experience.Tested one out in my FFL P03 flashlight and it's working fine. It steps up into turbo and holds as expected so the battery is providing adequate current. It's not pulling the full claimed 15A CDR, but I doubt there are many 18350 flashlights on the market that would.Overall no complaints, it appears to be a fairly good deal on a set of four quality 18350 batteries. Just keep in mind that they are button top style, make sure your device is compatible with them and doesn't require flat top.

The charger that I use (Nitecore UMS4) said that two of the four batteries have a charge status of "poor", which is disappointing. The charger manual says that poor indicates that the battery's internal resistance is higher than 250 megaohms, which means they will self-discharge faster than they should.

I will use these to make a battery pack for a radio I have. I used 18650 ones in the past but these will be a better size. I'll update the review with how well they last once I've had a chance to use them.

The media could not be loaded. I ran these 18 350 batteries through my opus charger/analyzer and instead of the labeled 800 MAH I got 723 MAH.The other thing I noticed there was a sticker on the box that the batteries came in which is now covered with a plain white sticker. And the sticker that was underneath clearly said Imren 18350 which tells me that they likely had to cover that either because they're not an authorized dealer? and they also had to change the listing to be certain not to post the Imren name.

Not a dud in the box! Don't laugh, it's not uncommon to receive a new battery that throws up a warning flag on my charger. All of these charged perfectly and powered my devices without issue. The price is fair because I believe these are decent quality. If I get a year out of my rechargeable cells I'm happy, hopefully these will make it but I have no reason to suspect they won't.They come in a typical plastic case and the battery's build quality feels a step above the norm. Physical sizing is exact for the part number. I'm going to be working these pretty hard and I'll update this review should any ungainly behavior arise.

Shorter than other cr123s but still work on some of my flashlights. Charge well and good capacity

All four batteries came fully charged, I tested each one at 3.8 volts out of the box. Since I got these to use in projects I have yet to build, I can't report on their longevity, but I tested one with some led's and it worked well and long. I have confidence these will be a part of my battery inventory for a while.
