Review: got this for a dash cam - I got this for a dash cam. My dash cam had 3 wires, one of which I am sure is just for the battery management. This battery only had two wires which is not unusual. I just connected those two wires with solder and left the 3rd wire off. I would like to make a disclaimer that I am not an electrical expert nor am I suggesting anyone do what I did. But my camera works now.
Review: Funciono perfecto y buena calidad.

### ⭐⭐⭐⭐ For MecArmy SGN3 Flashlight
*by T***E on July 28, 2021*

The light uses a 602030, but couldn't find one made by EEMB in that size. I'm hoping this, supposedly certified battery from EEMB, works better than the original and a cheapy replacement that I paid about $5 for on ebay. Neither one lasted very long. This 502030 250mAh battery ran for 13 plus hours on low mode. For anyone wanting to replace their MecArmy SGN3 battery, here's how to do it. I'll try and get back with an update in 6 months or so. The battery number(602030) is on the battery. To take it apart 1. Remove rubber on/off button cover, it comes out from the top 2. Pull out micro usb cover and don't try to remove it completely as that can't be done until the inner circuit board and battery are removed. 3. Use a utility blade to work the front section away from the main body, while making sure the micro usb port doesn't get hung up on the cutout of main body 4. Slowly work out the front section and battery. Do not pull the battery out by pulling on the wires that go to the circuit board. That's it. Just be careful when putting in a new battery as you don't want to short it out. I used heat-shrink insulation tubing to cover my connections. Solder/insulate 1 wire at a time to prevent a short. Don't mess with the battery or circuit board wire connection points. Cut in between at some point and solder the connections. Hope this helps.
