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.

For MecArmy SGN3 Flashlight
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.

This is the battery you need for Vantrue N2 Pro
Buy the reverse polarity because it's 1 dollar cheaper and you're gonna cut off the connector anyways. Youtube tutorial on battery replacement on this 8 dollar battery is much easier than buying a new dashcam for 100 bucks. Absolutely perfect and holds charge like brand new.

Do not buy!
your iPhone will hate this battery and you will pay the price! It comes up in the settings as being non-recognizable, which would be fine, except for the fact that it continuously overheat and quickly discharges. I honestly don't know if that's due to an intrinsic hardware, flaw, or simply because Apple makes it happen. Either way, if you put this battery in your phone you'll be miserable just like me...

Pay attention to the connector and Polarity!
Just as advertised! Little did I know the connector would be too large for the SkyRC GPS unit! So I had to alter it. It has 0.02mAh larger capacity than the stock battery, but squeezed in nicely after I changed the connector to the right size. The battery arrived @ 3.63V, and charged up nicely.

It works fine
So I purchased these batteries to replace the batteries in my Vantrue N2 dashcam. Vantrue does not back its product and have poor quality control in its design. They are the most expensive too. I'm not sure how they get so many 5 stars. I'm guessing they are using bots and/or paid scammers to provide false ratings which is a problem on Amazon which they are trying hard to address. These batteries are soldiered onto the circuit boards. The new replacements worked. I can't say if they last long or perform well. All I can say is that they worked and the device is up an running again. Keep in mind when shopping for replacement chargeable batteries of any type, you need to stay away for made in China batteries. These are probably from China but in my case, my performance needs were low compared to most applications. The batteries I used here were needed to allow time for the dashcam computer to shutoff properly so that the current video would close gracefully to avoid corruption. It is also needed for the sentry park mode when the car is off.

Exactly what I needed, great for wifi remote
I used this to replace the rather short-lived native battery in my Auvipal wireless remote. That was a 200mAh, 3.7-volt battery slightly thicker than this higher-amperage battery. The remote was not hard to crack open, and soldering in this replacement battery was quite straightforward. Because of its higher current, it performs better than the original.

Funktioniert einwandfrei mit Bosch Intuvia Power Pack 400. Habe das Teil in den Bediencomputer eingelötet, weil der alte Akku tiefenentleert war.

可搬用プリアンプの電源に、電池2で、+3.7V、ー3.7Vとして使用。チャージポンプのICで作る方法もありますが、こちらの方が取り出せる電流が段違いなので安定感あり。音も強さがある気がします。 組み込んだ状態でのバッテリ充電は少し、接続の工夫が必要。スイッチで切り替えてます。
