Quality weighted batteries!

You could tell the quality in this battery straight away the weight is heavier than cheaper none brand ones I bought and this holds the charge way better. I say cheaper this was about the same price as the other one... tge quality was just a cheaper knock off china tat.Highly recomend this company and there batteries and will defo be using them for every purchase in tge future! I'm just happy that I have finally found a company and I dont have to keep searching throuvh the minefield of pot luck.

Does not fit Acaia scales as descrbed

Bought this as the specs matched the battery in my Acaia coffee scales and the description said it was suitable for them, but the connector is the wrong size; the Acaia use a smaller connector. I swapped the connector over from the old battery was a bit of a hassle. Otherwise the battery seems good, no issues with it so far. A relatively cheap way to get your scales working again.

Check the polarity (I had to swap pins in the plug)

I'm glad I checked the polarity of the connector before I connected it to my Arduino microcontroller boards as they were reversed. The battery was delivered as described as described in the product listing but three of my boards (genuine Arduino and an Adafruit) all had the same polarity. I managed to pull the pins out of the plug and swap them. I was going to but a charger but I don't know what the standard is for these batteries. Do RC applications use a different polarity vs Microcontroller applications?

Works as intended. Very grateful it was sold here

I have a bluetooth wireless mechanical keyboard for years. I love it but recently, the old battery bloated and died. I removed the battery and took a while to find replacement.It works as soon as I plugged in the battery. And now my love for my keyboard is back. Thank you.
