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.
