This 3.7V can replace an identical 3.2V battery.
I got this 3.7V to replace an obsolete 3.2Vwhich otherwise is just the same (size and looks). I charge it with a simple USB cable that plugs into the battery and my computer. I use it to power a small electric plane (which took the 3.2V) and the plane works perfectly.

Took a few charges to retain full capacity
Replacement for dashcam battery. Quick delivery but appeared to take a few charges to reach reliable full capacity. Good value overall

Good replacement for Nexbase dashcam
Purchased to replace the battery in my Nexbase dashcam (apparently obsolete after 4 years but hey they kindly (!!) offered me 15% off a new one....). Perfect fit and working well so far, even if it lasts a couple of years it's much cheaper than buying a new dashcam ;-)

Works as it should, good price.
Works perfectly, I had to cut off the connector as the wires needed to be soldered on the public, plenty of wire to do this, works as it should, good vfm.

Dash cam Battery LP550230
This is a genuine battery replacement. The battery I had needed to be replaced as the original one blew up. This type is used for a dash cam. I seen this on Amazon and thought let me buy.I saved money and best thing is that I didn’t need to buy a new dash camera. I’m so glad as this type has no faults, and fits perfectly. The current is spot on and the battery size is the same. I would definitely recommend this seller as the item was packed and shipped out promptly. Thank you💯

Wrong size
Wrong size of battery. Despite the numbers matching. Can't return as not allowed to send back batteries. Has to bin it.

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。
