Using for my outside driveway sensors.
These batteries were what I needed for my outside sensors. The end fitting did not fit so I cut the old battery end fittings off and spliced them to the new batteries. They are working perfectly.

Nice fit to Anki Cosmo
I have used this battery to update Anki Cosmo robot as described various guides which used 503040 600 mAh. 603040 fits perfect and 800 mAh is much better for endurance - kids tests Cosmo for 2 hours and still very well changed, so I may assume resulting runtime will be 2.5 - 3 hours.

The Results Were Extremely Impressive !
Bought one sometime ago for an HMDX Bluetooth speaker. The original battery was a 500mAh rating. It died from sitting there not being charged. Put this one in, charged it completely. Been running it for hours in the cold 32°F temperature. It seems to just keep going. I play the device full volume and it doesn't quit. Perfect fit. Easy to replace. Bought a second one for another HMDX speaker, and will look for other devices that need replacement batteries.

Replacement battery for Garmin Edge 520
Use it to replace my battery in a Garmin Edge 520, perfect fit, and a bit more capacity then the original battery 800mAh vs 600mAh. The battery used about 30% on a 2,5 hour ride with 80% backlight on and Bluetooth connection.
