Excellent match for Golf GPS
Met all the requirements to replace a 2017 vintage battery of the same type! Works excellent, charges and holds charge. Gave extended life to this old device!

Poor charge
I ordered this as a replacement for my son’s magic track car. Specificly chose this for the longer battery life. It has been charged over night since getting it and charge lasts 10 secs before the car doesn’t work again. This keeps happening. Don’t know if I should send it back or buy a new car all together.

Perfect fit for my dash cam. Had to cut connector because it was a soldering job.

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...

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.

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.

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.
