    EEMB Are High Quality It Seems
  

*by T***E on Reviewed in the United States on February 2, 2022*

Previously bought an EEMB for my MecArmy SGN3 flashlight 7mos ago and it still gives full run times...12+ hrs on low. The original and a cheapy, about $5, didn't last 5mos. This one went into a VanTrue N1 Pro to replace the original. These definitely seem to be a quality battery.

    Perfect fit to repair Old Shark dash cam
  

*by S***N on Reviewed in the United States on February 24, 2021*

The battery failed in my 5-year-old Old Shark dash cam. After prying it apart (you need to remove a couple of screws too, one hidden under an inspection label) I saw that the old lithium polymer battery was puffy. Bad, bad, bad. This new battery arrived in a day. Perfect size. I was planning on cutting off the connector because the battery is soldered to the circuit board. Instead, I carefully cut the plastic tab holding each connector pin inside the connector housing and extracted the pin. I soldered these pins directly to the circuit board. They stiffen the wires so they won't accidentally short out.
