I was sent some more interesting cells to test. One type is basically nothing special, but a pair of high-current tabless cells really caught my interest. I definitely haven't had anything like these before, so I think this will be useful.

This is the third part of my review of various batteries. Today we're looking at completely different cells: a different size, manufacturer, and chemistry. But in my opinion, cells like these are just as much in demand today as the ones covered previously.

Continuing the previous comprehensive review, this time with a pair of 21700 batteries: one is geared more toward high current, the other toward high capacity.

Not long ago, one of my readers got in touch again and asked me to test some batteries. Why not? I find it interesting, and it’s useful for you, so I agreed. Today is part one: 18650 cells from the same manufacturer, the well-known EVE.

Sometimes, when looking at tool batteries, I wondered why no one had combined one with a power bank. Yes, I’d come across adapters that offered a similar feature, though only in one direction: discharging. But recently I saw something in the TPcell store that really caught my interest: a battery with a built-in power bank.

Na-ion batteries based on a relatively new chemistry (though that depends on how you look at it) have finally made their way to me. I bought them specifically for a review and to satisfy my own curiosity, and now I can share the results of some tests with you. I think you'll find them interesting.

Well, is it time for a tasty battery review? Meet the 4695-size lithium batteries. I hope you find this interesting.

The second test subjects from the batch I received—and this time, these are batteries I hadn't tested before. On top of that, they're simply more interesting than the previous ones.

I recently received three types of batteries to test, and decided it would be useful to share the results and my thoughts on them.

Some time ago, my new 230 Ah CALB batteries finally arrived. They were sent directly by the manufacturer, so I tested them as best I could, and today I’ll show you what they’re like.

A new drill driver has shown up at my place—or rather, not exactly new, more like not very old. And it didn’t just show up; I brought it home myself. Anyway, I decided to buy an extra battery for it, and today I’ll tell you how that turned out.

More batteries sent to me by a blog reader. This time, though, we're looking at the very common 32700 form factor. I've had batteries of this size before, with various capacities, so I'll not only show you the new ones but also compare them with the previous ones.

These are the third batteries I've received from a reader, and this time they're from the relatively well-known BAK. Sure, they're not Samsung or Murata, but BAK is still a recognizable name.

The second set of batteries from a group shipment sent by one of my readers. This time they’re some no-name (at least to me) Gotion/Guoxuan cells, but as it turns out, they’re actually quite interesting.

It's been a while since I wrote a review. I've been pretty swamped lately with work on new electronic loads. But a little while ago, one of my readers sent me several different types of batteries to test, and today I'm reviewing the first ones.

I recently posted a review of LG HE2 batteries, but as I mentioned then, someone sent me a couple more batteries to test. Many thanks to him for that, since battery reviews are very useful.

One of my readers contacted me asking me to investigate and possibly help determine whether the batteries he received from Nkon were genuine. In this case, they were LG ICR18650-HE2 2500mAh batteries.

As luck would have it, I got my hands on one of the new batteries from Molicel. It’s a very interesting cell, primarily because it combines relatively high capacity with a high rated discharge current. Inspection, tests, comparisons, conclusions—the usual.
