Great replacement battery.
Great replacement of the battery in an old car hands free Bluetooth speaker found in storage after years which was no longer charging or powering up. Had to snip away the wire connector plug to allow for direct soldering to circuit board but this was straight forward using snips. The battery arrived precharged at 70% level confirmed once connected to Bluetooth and offers a higher maH to the OEM battery replaced. Size and fit are great as expected.

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.

Lead never again
Charges faster the lead weight a fraction of lead holds way more charge than lead. I'm never going back I have 3 bat packs for my wheelchair the other 2 will get changed to lithium so happy for the change. More charging cycles just better in everyway

Perfect replacement for a NUX Mighty Plug Pro
A great battery to replace a failed (blown/inflated) battery on a MUX Mighty Plug Pro. Just snip the connector off (without shorting the battery out!) and solder the wires to the contact points after removing the old one! It is slightly smaller than the original in length, however the battery that comes in the NUX from the factory is a custom battery, so an exact replacement is not commercially available. Very happy!

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?
