Suspicions crept in even at the moment the package was https://jiji.com.gh/computers-and-laptops/hp-probook-640 handed over to the SDEK office: it was too square and practical inside. In the process of charging, an indication of the process is visible through a specially trained
Charging is impossible without the nasty blue LED 🙂 Let’s look further: it looks like an ordinary "Krona", the case is made of white thin plastic, weight is 28 grams (kosher Varta weighs 45g.). I reassured the seller with the promise of a review with dismemberment, which I actually do. Even the cheapest salt batteries have a film. I’m pulling out the giblets. The inscription “USB rechargeable lithium battery” and a caring microUSB pointer with an arrow in the direction of the bottom hint at the unusualness. The quick-witted reader has already realized that we were short of voltage and something is wrong here. The review is actually spontaneous, the seller sent these batteries instead of the usual lithium 14500 (AA) format for installation in a people’s nosoder for a dollar. At the end of the charge, the voltage at the terminals is 8.5v, when turned off, it drops to 8.4v. While you are making tea, you can read about the younger brother Ni-MH Palo 6F22 9V 300mah I remove the film, pick it up and open the lid, two current-carrying bars are visible inside. The seller simply throws the batteries into an ordinary bag of bubble wrap, and with chaotic
kicks movements at the post office, the open terminals of different batteries can short circuit with each other. And as it turned out – not good at all.
Batteries do not have individual packaging or at least stickers on the terminals – this is not good. Opening a dispute, photo video and a quick full refund. UPD By popular demand, I figured out the protection of the cells, painted the diagram and added a high-resolution photo. Inside is a package of two lithium cells and a charge/protection board. On the top side, everything is expected, below is the same recharging socket.
