I've been using this toner regularly, and it has made a noticeable difference in my skin. It helps remove excess oil, minimizes the appearance of pores, and leaves my face feeling clean and refreshed without over-drying.

Ensure your device is switched off before installation. Press down on the Spring S2 terminals to slide the battery directly into the standard 4R25 lantern housing compartment, matching positive and negative alignments. To recharge, connect the provided cable to the integrated Type-C port on the battery and plug it into a standard mobile phone adapter or compatible battery charger.
Generic Lithium Iron Phosphate cells, integrated Battery Management System circuit board, steel alloy top spring terminals, and a durable polymer outer protective housing case.
Wonderful deal! I have 4 dogs and these work just like the originals.
Our Cable Box lit up saying it had to have a new battery, and inside indicated 12V 7-8A.So this was just the ticket to slide into place as a reasonable replacement.The one I took out was installed 21 years ago... so I'm hoping that this one will be able to hold out and last at least 10 or 15? . .Works Well! Discharging and recharging over its usable lifetime, I'm sure it's crafted for some basic longevity, but I guess only time will tell where things stand after a decade or two...At any rate, it slid into place as an easy replacement and I put a label on it to say when it was latest. Let's see who finds it in what shape hopefully plenty of years down the road.
Works as it should thank you
Nice battery
Acquired in Dec 25' for $23.99. I wanted to replace 15+ year worn backup battery in the original Verison FIOS wall mount DC power supply. It's is right for in the housing perfectly fine as you'd expect. If I'm lucky, it'll last for the remaining useful life for this set of hardware.
