Somehow, I haven't been writing many reviews of AliExpress products lately, but I just had to write one about this item. It all started when, on August 25, I ordered a whole bunch of little things (probably like many others did)—some for myself and some for friends who'd asked me to. The packages have started arriving recently. I'll probably write about some of the other things I ordered too, since a few of them are interesting. But for now, here's a review and complaint.

Many of you are probably familiar with this situation: at the worst possible moment, your camera (and plenty of other devices) says, “Battery depleted”—and it doesn’t care that you only have a couple of shots left to take. Batteries usually come in genuine and clone versions; this review is about the latter.

Yes, you read that right: I’ve already reviewed these batteries, including putting them to use. But this review is different from the previous one. I’ll also answer some questions that readers often ask about products received for review. Anyway, if you’re interested, the rest is as always below the fold.

While working on one of my long-running projects, which I started late last year, I needed some batteries. I had the idea of adding a backup power source to the device I'm building. So I decided to order these batteries and take a look at what they were like. So, we'll be testing 18650 batteries with a claimed capacity of 2800 mAh. Anyway, more after the jump.

And so, my brief run of bad luck in experiments with various batteries has come to an end. As usual, I ordered the battery for a specific purpose, but read on to find out what it was and about the battery itself.

This story began when an acquaintance brought me a cordless drill for repair. He bought it on sale when a store was closing. The warranty has expired, and it won't work. When I opened it up, I found that one of the batteries had died. Then batteries for power tools showed up on the ChinaBay website—yes, that's exactly what they were called: Battery for Power Tool. I couldn't just pass them by, so I ordered one for testing. Read on for the rest of the story, the test results, and how I put it to use.

This time I decided to experiment again with batteries in a less common size. Read on to find out what I got (and didn't get) in the end.

Just recently, TrustFire came up in one of my battery reviews. I had just received some batteries from this very brand, and they were 18650s. This review won't be very long, but it may be useful. As always, the rest is after the jump.

At work, we have quite a few portable radios, powered by Ni-MH batteries. They charge them any old way, so the batteries fail quickly. Lithium batteries were ordered as replacements. If you're interested, read on after the break.

I have an ESR meter built using a circuit designed by GO, a fellow member of the pro-radio forum. I’m sure some of you use this meter too. I use it all the time, but when it runs on a 9V battery with the display backlight on, it drains batteries pretty quickly, so I decided to order a pair of rechargeable batteries for it. Details after the jump.
