Electronics and technology blog    /    Materials for May 2022 year

I’ll try to add updates here about what’s happening in Kharkiv. I may also add material from previous days.

More batteries, and this time they’re also Sanyo cells from a teardown, but in the more compact 14500 size. The results are pretty good too, which is to be expected from branded batteries.

More batteries, this time from the well-known Sanyo brand. What makes them especially interesting is that I bought them from Nkon as Reclaimed. People often ask me whether it’s worth buying batteries like these from Nkon, since they can be quite a bargain. This review answers that question.

I've been asked about testing BAK batteries more than once, and I even had one of this company's products. But recently, circumstances worked out so that I got my hands on a few more batteries, and there was another BAK in the batch, which naturally caught my interest.

As it happened, a battery for an e-reader from the well-known Kindle brand ended up in my hands, and I decided to test it. I was especially interested because not only had I bought it on AliExpress, but it had also been sitting in a box for a couple of years.
