The batteries perform well but the charger was cheaply made. After the first round of charging, I have to wiggle the cord and leave it “just so” for it to charge.To be fair, I wasn’t expecting a quality charged and batteries at this price point

Plug and Play. Just plug in the USB cord to a power supply or computer, put in the batteries, and the RED light will change to GREEN when the batteries are fully charged. Works well.

This battery saved my phone. The original battery that came with my phone went from 100% to 80% within 2 minutes! It was horrible. But this Taeozi battery has breathed new life into my phone and now I don't have to worry about it draining within minutes. Very happy with this purchase!

We got this battery after a previous one from a different manufacturer failed after 3 days. With the previous battery, the phone started having issues after three days. This one has lasted three weeks in extreme heat (95+) plus in the car during work. The reason for 3 stars for battery life is due to the fact that yesterday, the battery did not last as long as it normally does, The same thing was happening to my significant other's phone too so it is something to keep an eye on.

My husbands battery was swollen and wouldn't hold a charge. We bought this battery and it works like the original one. Love it!!

As the LG V20 ages, it gets harder and harder to find support for it. As the last "Hero" phone with a replaceable battery, it is hard to give up the phone for those of us that like the option. Mine was dying, the battery I had was not holding a charge, or charging completely. As LG has stopped supporting it, no manufacturer option was there. A battery bought on EBay was a dud. Enter the Taeozi 3300. I took a flier on this based on the user reviews. I am EXTREMELY pleased. It fit perfect. I did the suggested "run it down to zero, charge it to 100 completely" three times as the manufacturer suggested. This battery has improved nearly everything and lasts all day. It is so much better. I do have one problem: My charge time is slow. It takes an awful long time to get it fully charged. The only reason it is not 5 stars. But it saved my phone. May buy a second one just to keep as a spare.Update: This battery is fantastic. Better than the original. Has held up long term very well.
