9V USB қайта зарядталатын батарея 9V 1200mAh 6F22 литий-ионды батарея Мультиметрлік металл детекторы электр гитараға арналған USB батареялары

Looks very good. I think it's great, 9V block for charging with much more power than a battery or a normal rechargeable battery. I'll install it in my multimeter or one of my smoke detectors, then it will last forever.

Not as described, it is not 9 volts. I am attaching comparison photos with a regular battery. It's a shame to sell electronic waste. It is because of such producers that our planet suffers. I DO NOT RECOMMEND !!!

I received 4 batteries, according to the order. All 4 show 0 (zero) volts when measuring. I return After charging all ac show 8.4v

Super fast and super good goods with good quality and very good packaging. Still needs to be tested. Are packaged separately again. Very happy to be with you again.
