Got to use as a replacement battery in hair trimmer
Have a good quality cordless hair trimmer I have used for years. The battery had reached it's end of life and would no longer hold a charge. Though the oem battery was held on place with tabs on both terminals , I was easily able to clip those connections and replace those connections with the leads on this battery. Worked perfectly. Now my clippers run like new.

Check wiring polarity before using!
Not a big deal, but the polarity of the wires inserted into the plug was the opposite of what I expected. The positive/negative wires were flipped from all the other similar batteries I own, and also from the devices I have that use the battery. I had to cut the wires from the plug, which made this a pain to use. I'll survive.

Bought for sprayer
I bought this for a sprayer that I thought the battery was dead but there was a defect it the controller and not battery. So I use this now for LED's and it works fine. The wires a little smaller than I wanted but they arent "flimsy"

It Works
I got this to replace the battery in a rechargeable camera light. The battery came with about 30% charge, which can indicate it has been sitting quite some time after being manufactured. So far, it has served its job and worked fine without issue.There is a concern with the thickness of the wires as this battery has the ability to put out far more amps than the wires can handle safely.Overall: When buying any generic lithium battery, one should know the basics of Watt's law and the power needs of the device / project. I personally would not trust this with more than 5A, but would recommend it for light duty applications at the price point.

Little larger than the battery in my RC Boat but made it run longer
This battery was a good upgrade for my RC boat and made it run for longer. However, it was bigger than the original battery, so it didn't fit as well, but if you're like me, this will make a good hobby project in combination with some drone motors or something. It does come with a charger.
